Sea buckthorn (Hippophae rhamnoides L.) is in the focus of interest mainly for its positive
effects on health of both human and animal organisms. The whole plant of sea buckthorn and
especially its berries are a source of a large number of different bioactive compounds. The
greatest attention has been drawn to its high content of vitamins, minerals, natural antioxidants,
n-3 and n-6 fatty acids, and proteins. Sea buckthorn is valued for its antioxidant, cardioprotective,
antiatherogenic, antidiabetic, hepatoprotective, anti-carcinogenic, immunomodulatory, antiviral,
antibacterial, anti-inammatory and vasorelaxant effects. Due to these and other positive effects,
the plant is included in both human and animal nutrition, in the latter case to increase the
biological value of animal products. This review summarises the botanical characteristics of sea
buckthorn, lists the bio-active substances contained in individual parts of the plant, their effects
in the prevention of a number of different diseases and their possible utilisation in human and
animal nutrition.
Bioactive substances, therapeutic effects, functional food, nutrients
For humankind, vegetation is a source of basic nutrients, raw materials for industrial
use as well as many bioactive substances. Plants with exceptional properties and a wide
range of application include, beside others, the sea buckthorn (Hippophae rhamnoides
L.). Its Latin name is derived from the words “hippo”, meaning horse, and “phaos”, which
is gloss or are (Michel et al. 2012). Thus the compound may be translated as a shining
horse (Li and Beverid ge 2003), or more freely as a glossy coat (Val íček and Havelk a
Botanical characteristics
Sea buckthorn (Hippophae rhamnoides L.) is included in the Elaeagnaceae family
ezníček and Plšek 2008). It is a family of eudicots of the Rosales order. The family
includes around 100 species in three genera mostly found in the moderate geographical
latitudes of the Northern hemisphere. Seaberries are classied in the plant taxonomy into
six species and 12 subspecies (Bal et al. 2011). Sea buckthorn is native to Central Asia
ez níček and P ek 2008) and North-Western Europe. At present, it is also grown in
Canada and the USA (Yang and Ka llio 2001). Seaberries grown in the Czech Republic
mainly include sea buckthorn and Russian silverberry.
Seaberries are shrubs or small trees mostly no more than 3 to 4 m high (Michel et al.
2012). They are trees with alternate, often silver-gray, simple leaves and blossom without
crown. Seaberry branches are often covered with numerous rigid thorns (Řezníček and
Plšek 2008). Seaberries are dioecious and anemophilous. Male plants have ower buds ×
2–3 bigger than female plants. Flowers do not produce nectar and therefore, pollination by
insects is not possible; the only possibility is wind pollination (Li and Beveridge 2003).

Sea buckthorn has narrow lanceolate alternate leaves (Řezníček and Plšek 2008;
Michel et al. 2012). The top of the leaf is dark green. The bottom of the leaf is green with
silver-gray tone. The silver-gray colouring is caused by the presence of trichomes that are
only found on the bottom of leaves (Li and Beveridge 2003).
Seaberries naturally grow in higher altitudes at about 2000 to 3600 metres above sea
level. They are highly resistant to temperature extremes, well tolerating temperatures in
the range of –45 to +43 °C. They typically grow on riverbanks and on the sunny side of
steep slopes (Dhyani et al. 2007). Seaberries well tolerate drought, high levels of soil
salinity, and acid soils (Khan et al. 2010). Their root system is well organised. The roots
bear bulbils of dove egg size containing bacteria binding nitrogen in soil (Valíček and
Havelka 2008), as well as other essential components (Li and Beveridge 2003). The
roots are strong and that is why seaberries are often used to protect the soil against erosion
or in recultivation processes (Kumar and Sagar 2007).
Berries as well as other parts of sea buckthorn represent a rich source of biologically
active compounds. For this reason the plant has been in the centre of attention virtually
world-wide. The chemical and nutritional composition of sea buckhorn berries as well as
the content of bioactive compounds depend on many factors. The most important factors
include different subspecies, origin, climate conditions, time of harvesting, and methods of
processing (Bal et al. 2011).
Berries and seed of sea buckthorn
The numerous fruits are dark yellow, orange or red when ripe, oval shaped and 6–9 mm
long. The fruit consists of a seed wrapped in soft, juicy and eshy tissue – the pulp. The
seed is 2.8 to 4.2 mm long, dark brown, ellipse-shaped and glossy on the surface (Michel
et al. 2012).
The chemical composition of berries depends on the variety, climate conditions, fruit
size, ripeness and the processing method (Leskinen et al. 2010). Sea buckthorn and
especially its berries provide a rich source of many minerals, including, but not limited to
Ca, P, Fe, and K. Sea buckthorn has a large content of vitamin C, several-fold compared
to other fruits (Christaki 2012). The vitamin C content in sea buckthorn ranges between
360 and 2500 mg/100 g (Bal et al. 2011). The plant is a valuable source of the vitamin B
group, mainly B1 (thiamine) and B2 (riboavin) (Christaki 2012). Other vitamins rich
in sea buckthorn include, for example, vitamin E (Michel et al. 2012), vitamins A and K
(Bekker and Glushenkova 2001; Fatima et al. 2012). The berries provide a good source
of carotenoids, mainly ß-caroten, lycopene, lutein, and zeaxantin (Michel et al. 2012). The
saccharide content is also high. The most common carbohydrates are glucose, fructose,
and xylose. All parts of the plant contain many different proteins, mainly albumins and
globulins (Li and Beveridge 2003). Sea buckthorn is a source of organic acids, mainly
malic acid, quinic acid, oxalic acid, citric acid, and tartaric acid. Sea buckthorn is a good
source of avonoids too, mainly quercetin, kaempferol, myricetin, and isorhamnetin, and
an important source of tocopherols (Fatima et al. 2012).
The pulp
The pulp of sea buckthorn contains mainly α-, ß- and γ-carotens, glycopene, and zeaxantin.
Vitamin B group is mainly represented by B1 (thiamine), B2 (riboavin), B6 (pyridoxine),
vitamin PP (nicotinamine, niacin, vitamin B3), and folic acid necessary for nucleic acid
synthesis. The vitamin C content depends on the variety and natural conditions. Plants
growing in Central Asia contain 150–200 mg/100 g, and Alpine plants contain around
800 mg/100 g. The berries do not contain ascorbinase for ascorbic acidolysis, thus vitamin
C is well preserved in dry fruit and in products (Valíček and Havelka 2008). The peel of
the stem and fruits contains 5-hydroxytryptamine, which is found rarely in plants (Kumar
et al. 2011). This substance (5-hydroxytryptamine) is used for treatment of post-shock
Sea buckthorn leaves
The leaves contain a remarkable quantity of nutrients and bioactive substances, mainly
phenolic. They contain on average 3.8% of saccharides, 0.2% of protopectin, 1% of
organic acids, 170 mg/100 g of catechin, polyphenols, carotenoid lycopene, bioavonoids,
and coumarins. The leaves also contain a signicant concentration of vitamin C (up to
370 mg/100 g) and tannins (8%) (Valíček and Havelka 2008).
Sea buckthorn oils
Two oil types may be extracted from the sea buckthorn, either from the pulp or from the
seeds. The pulp contains 4–13% of oil, and dry pulp contains about 20–25% of oil (Zeb
2006; Valíček and Havelka 2008). Sea buckthorn is a good source of mainly unsaturated
fatty acids (Christaki 2012). The pulp oil contains 180–240 mg of carotenoids in 100 g,
of them 40–100 mg in form of caroten, 110–330 mg of vitamin E and unsaturated fatty
acids, mainly linoleic and linolenic acids. Specic types of acids include ursolic acid and
oleanolic acid, with anti-inammatory, wound healing, toning and blood pressure reducing
effects (Valíček and Havelka 2008). The pulp oil contains the highest concentration of
palmitoleic acid (16:1, n-7), up to 43% (Fatima et al. 2012).
Sea buckthorn seeds contain 8–20% oil (Kumar et al. 2011). The oil content is mainly
affected by the harvest time, size, and colour of berries (Yang and Kallio 2002). Seed
oil mainly includes unsaturated fatty acids – 90% (linoleic 47 mg, linolenic 18 mg, oleic
16 mg) and saturated palmitic acid (Valíček and Havelka 2008). Seed oil is the only oil
with the linoleic acid to linolenic acid ratio of 1:1 (Yang and Kallio 2002; Cenkowski
et al. 2006; Kumar et al. 2011).
Oil pressed from sea buckthorn seeds is mainly rich in essential fatty acids such as
linoleic acid (18:2, n-6), making up to 42% of the total fatty acid, and α-linolenic acid
(18:3, n-3), up to nearly 39% of the total fatty acid content. Sea buckthorn is also a good
source of oleic acid (18:1) (Christaki 2012). In addition to the above, the oil also contains
other n-3 and n-6 as well as n-7 and n-9 fatty acids, which are present in lower quantities
(Solcan et al. 2013).
Selected major effects on health of organisms
The sea buckthorn berries have been used for centuries by inhabitants of Europe, Central
and South-Eastern Asia in traditional medicine for treatment of different diseases as well as
for disease prevention (Li and Beveridge 2003; Michel et al. 2012). In China sea berries
have been used in traditional medicine for centuries (Li and Beveridge 2003).
At present, sea buckthorn has become popular especially for its positive effects on
the human organism. Sea buckthorn is valued for its antioxidant, cardioprotective,
antiatherogenic, antidiabetic, hepatoprotective, anti-carcinogenic, immunomodulating,
antiviral, antibacterial, anti-inammatory and vasodilating effects (Table 1). It also reduces
occurrence of stomach ulcers, supports wound healing, accelerates treatment of skin
disorders and reduces pain (Suryakumar and Gupta 2011; Christaki 2012; Michel et
al. 2012). Other important properties of sea buckthorn include its cytoprotective effects.
Sea buckthorn acts positively against asthma and pulmonary diseases (Upadhyay et al.
2010), against increased sebum secretion and affects platelet aggregation (Khan et al.
2010). Its antistress and adaptogenic activities have been conrmed (Michel et al. 2012).
Sea buckthorn also positively affects metabolic diseases (Bal et al. 2011), with the
ability to slow down ageing and protect against radiation-induced damage, accelerate the
healing of burns and frostbites, and reduce hair loss. Sea buckthorn also positively affects
mental functions, in particular reducing memory loss in elderly people. Its positive effects
have been utilised for acceleration of wound healing, especially in people after ear, nose
and throat operations where seaberry oil has been part of the treatment. The oil has also
been used for protection against solar radiation (Li and Beveridge 2003). Sea berry
products may be used in various drug forms from liquids via powder, patches, pastes, lms,
ointments and aerosols to suppositories (Li and Beveridge 2003).
Antioxidant effects and immunomodulating properties
Sea buckthorn contains many natural antioxidants in all of its parts. Its leaves, stems,
tubers, roots as well as blossom contain a high content of ascorbic acid (vitamin C), and
also carotenoids, polyphenols, avonoids, tocopherols, alkaloids, chlorophyll derivates,
amino acids and amines (Bal et al. 2011; Christaki 2012). Other natural antioxidants

Increased utilisation of vitamin A
present in sea buckthorn include sterols, tannins, vitamins, and minerals (Kumar et al.
Natural antioxidants inhibit or delay the oxidation of other molecules by inhibiting the
initiation or propagation of oxidizing chain reactions (Bal et al. 2011). Free radicals,
a product of cellular metabolism, can cause a number of diseases by exogenous chemical
or stress effects (cancer, diabetes mellitus, cardiovascular and nerve system disorders)
(Upadhyay et al. 2010; Kumar et al. 2013). Kim et al. (2011) evaluated the antioxidant and
alpha-glycosidase inhibitory effects from the extract, fractions, and isolated compounds of
sea buckthorn leaves The butanol fraction, which contained the highest amount of phenolic
compounds, showed higher radical-scavenging activity and also the most powerful alpha-
glycosidase inhibitory effect.
Flavonoids of sea buckthorn also provide antioxidant and anticarcinogenic effects. They
protect cells against oxidative damage, subsequent genetic mutations, and cancer (Gao et
al. 2000; Zeb 2006; Suryakumar and Gupta 2011). A potential chemopreventive effect
of sea buckthorn berries in mice was observed by Suryakumar and Gupta (2011). In
high-fat diet-induced obese mice sea buckthorn leaf tea proved their antioxidant effect and
effect of visceral obesity reduction (Lee et al. 2011).
Cardioprotective effects
Flavonoids contained in sea buckthorn as well as the unsaturated fatty acids contained
in sea berry oil are able to improve the function of the cardiovascular system (Zeb
2006; Suryakumar and Gupta 2011) and to prevent heart diseases (Christaki 2012).
Flavonoids show a favourable effect on the strength of heart muscle contraction and the
cardiac rhythm (Li and Beveridge 2003; Kumar et al. 2013). The effect of sea buckthorn
on cardiovascular functions and coronary microvessels in spontaneously hypertensive
stroke-prone rats was studied by Koyama et al. (2009). Experimental rats were fed
a feed enriched with sea buckthorn powder at the amount of 0.7 g/kg of feed for 60 days.
The effects included a signicant decrease of the mean arterial blood pressure, heart rate,
total plasma cholesterol, triglycerides and glycated haemoglobin in the rats. The arteriolar
capillary portions of microvessels expressing alkaline phosphatase decreased, but there was
a trend for an increase in the total capillary density. It was concluded that sea buckthorn
fruits improved the metabolic processes and reduced hypertensive stress on the ventricular
Another study focusing on the antihypertensive effect of total avonoids from sea
buckthorn seeds and mechanism of their action in long-term sucrose-fed rats by evaluating
its ability to regulate insulin and angiotensin II concentrations was done by Pang et al.
(2008). Feeding a high sucrose diet (HS: 77% kJ from carbohydrates, 16% from proteins,
6% from lipids) for 6 weeks resulted in a signicant increase of the systolic blood pressure
by 25.6%, plasmatic insulin concentrations by 114.24%, triglyceride contents by 82.14%,
and activated angiotensin II contents in the heart and the kidneys. Administration of a diet
enriched with sea buckthorn avonoids signicantly reduced the increased hypertension,
hyperinsulinaemia and dyslipidaemia. In addition, this diet (mainly at 150 mg/kg/day)
increased the blood concentration of circulating angiotensin II. The results showed that
the antihypertensive effect of the sea buckthorn enriched diet at least in part improved
insulin sensitivity and blocked the angiotensin II signal path. The study proved that a diet
with total avonoids extracted from sea buckthorn seed residues may be used for treatment
of hyperinsulinaemia in the non-diabetic state with cardiovascular diseases (Pang et al.
The most important avonoids are quercetin and isorhamnetin (Suryakumar and
Gupta 2011). The abovementioned effects are probably achieved by reduced blood glucose
concentrations, absorption of free radicals (Suomela et al. 2006), reduced susceptibility of
low-density lipoproteins to oxidation (Eccleston et al. 2002) and anti-hypertensive effect
(Wang et al. 2011).
Antiatherogenic effects
Sea buckthorn food supplementation has been proved to be able to reduce total cholesterol,
triglycerides and LDL-cholesterol, and increase HDL-cholesterol levels in comparison to
sea buckthorn-free diet (Yang and Kallio 2002; Suryakumar and Gupta 2011). Seed
oil is the most effective in this area (Christaki 2012). Basu et al. (2007) found that seed
oil of seaberries showed signicant antiatherogenic and cardioprotective effects in rabbits.
Antibacterial and antiviral effects
Antibiotic treatment of bacterial diseases is in many cases less effective and leaves
residues in animal products (e.g., bee products, etc.). It is therefore necessary to nd an
alternative, especially using natural ingredients (Kuzyšinová et al. 2014). The phenolic
compounds of sea buckthorn represent the main group of phytochemicals which exhibit
antibacterial and also antiviral effects. These compounds both suppress gram-negative
bacteria (Khan et al. 2010) and reduce gram-positive bacteria (Kumar and Sagar 2007).
A recent study involves a new phytochemical substance called hipporamin. It is a phenolic
compound from a nature source (Michel et al. 2012). Hipporamin positively suppresses
a wide spectrum of bacterial as well as viral diseases (Suryakumar and Gupta 2011).
Antimicrobial activities have also been reported for sea buckthorn berries (Puupponen-
Pimia et al. 2001), seeds (Chauhan et al. 2007) and leaves (Upadhyay et al. 2010).
Mic hel et al. (2012) report that the active agents contained in sea buckthorn manly inhibit
Bacillus cereus, Pseudomonas aeruginosa, Staphylococcus aureus, Yersinia enterocolitica
and Enterococus faecalis bacteria. These effects are mainly shown by extracts from sea
buckthorn leaves. Oil obtained by pressing is a very effective inhibitor of bacterial growth,
especially of Escherichia coli (Christaki 2012). Also Kaushal and Sharma (2011)
conrmed that sea buckthorn seed oil showed good antimicrobial properties (growth
inhibition zone diam. 4.0 mm) against Escherichia coli.
Sea buckthorn has also shown unique biological properties against viral diseases, anti-
viral activity against the inuenza virus and herpes virus. The suppressing effect on the
inuenza virus is provided by inhibition of viral neuraminidase present in the virus. Sea
buckthorn also positively inhibits HIV infections in cellular cultures (Shipu lina et al.
2005; Michel et al. 2012). J ain et al. (2008) suggest that the sea buckthorn leaf extract
has a signicant anti-Dengue activity and has a potential for the treatment of Dengue fever.
Anti-inammatory effects
In traditional medicine sea buckthorn has been used for treatment of stomach ulcers for its
effect on anti-inammatory mediators (Xing 2002). Oil and leaves support regeneration of
skin wounds and support treatment of skin disorders (Upadh yay et al. 2009). Palmitoleic
acid contained in sea buckthorn is a component of skin fat and thus represents a valuable
component of topical treatment of cellular tissue and wounds (Bal et al. 2011; Kumar et
al. 2011). Sea buckthorn leaves are able to protect irradiated mice against inammation
(Tiwari and Bala 2011). Li and Bever idge (2003) report that Russian cosmonauts used
sea buckthorn berries in their diet and oils in creams for protection against solar radiation.
Antidiabetic effects
Other positives of sea buckthorn include mitigation of the symptoms of diabetes mellitus.
This effect is caused by achieving reduced blood glucose concentrations by dietary
supplementation with sea buckthorn (Chr istak i 2012).
In diabetes, sea buckthorn not only affected the lowering of blood sugar including fasting
blood glucose and two h postprandial blood glucose, but also the treating of complications.
Sea buckthorn has been shown to be effective in cell cultures, animal studies, and clinical
practice. Although sea buckthorn has been shown to have positive effects in relieving
symptoms such as fatigue, dry mouth, and dry eye in non-diabetic diseases, it is still
unclear whether it has a therapeutic effect on the symptoms of diabetes. Studies have to be
conducted to test and verify the effect of sea buckthorn on symptoms in diabetic patients.
On the whole, sea buckthorn is a candidate for complementary therapy of diabetes (Wang
et al. 2011).
Anticarcinogenic activity
Favourable effects of sea buckthorn also include the anticarcinogenic activity (Mi chel
et al. 2012). Anticarcinogenic effects have mainly been reported for substances extracted
from sea buckthorn berries (Ch ristak i 2012). One of the main components contributing
to this effect is quercetin that induces apoptosis in cancer cells. The best effect has been
reported in relation to the treatment of patients with colon cancer, leukaemia, and prostatic
carcinoma (Pate l et al. 2012). Other studies suggest that sea buckthorn oil alleviates
haematological damage caused by chemotherapy, such as part of treatment of leukaemia
(Yan g and Kall io 2002). Therapeutic effects are ascribed to substances such as catechin,
gallocatechin, and epigallocatechin (Kha n et al. 2010). Sea buckthorn has also been
reported to favourably affect the inhibition of certain factors causing stomach cancer in
humans (Li and Bev eridge 2003).
Yasukawa et al. (2009) isolated and identied three phenolic compounds, (+)-catechin,
(+)-gallocatechin, and (-)-epigallocatechin and a tritepenoid, ursolic acid from the active
fraction of the 70% ethanol extract of sea buckthorn which exhibited a remarkable anti-
tumour activity.
Induction of the apoptotic activity and apoptotic morphological changes of the nucleus
including chromatin condensation were also observed in the HL-60 cells treated with some
of the avonols isolated from sea buckthorn such as quercetin, kaempherol, and myricetin
(Hibasami et al. 2005).
Hepatoprotective effects
The liver is often affected by a multitude of environmental pollutants and drugs, all
of which place a burden on this vital organ which can damage and weaken the liver and
eventually lead to hepatitis or cirrhosis (Zimmerman and Ishak 1994). Sea buckthorn has
shown numerous positive effects on liver protection and treatment of liver diseases (Barkat
et al. 2010). Hepatotoxins such as ethanol, carbon tetrachloride, and acetaminophen cause
various degrees of hepatocyte damage, degeneration, and subsequent death of hepatic cells
(Ramesbabu et al. 2011; Michel et al. 2012; Solcan et al. 2013). Substances contained
in sea buckthorn such as unsaturated fatty acids, α-tocopherol or ß-caroten protect hepatic
cells against damage by hepatotoxins (Ramesbabu et al. 2011). Flavonoids are mainly
responsible for protection against liver fattening (Li and Beveridge 2003). Sea buckthorn
might also contribute to prevention of liver brosis in the future (Suryakumar and Gupta
A trial focused on the effect of sea buckthorn on the toxicity of oxidized cholesterol
proved that sea buckthorn administered in the diet reduced plasma concentrations of alanine
transaminase (ALT), aspartate transaminase (AST), and alkalic phosphatase (ALP), which
indicates that the plant may have a protective effect against hepatotoxicity induced by
oxidized cholesterol (Yeh et al. 2012).
The hepatoprotective activity of sea buckthorn leaves and seed oil was evaluated using
carbon tetrachloride (CCl4) induced hepatic damage in animals (Geetha et al. 2008; Hsu
et al. 2009). The results showed that sea buckthorn leaf alcoholic extract as well as seed oil
ameliorated CCl4-induced liver injury as evidenced by both histological and biochemical
In a study by Maheshwari et al. (2011), some of the phenolic constituents of sea
buckthorn leaves, such as gallic acid, myricetin, quercetin, kaempferol, and isorhamnetin
were identied in the phenol rich fraction by reverse-phase high-performance liquid
chromatography (RP-HPLC). Oral administration of the phenol rich fraction at dose of
25–75 mg/kg body weight signicantly protected from CCl4 induced elevation in aspartate
aminotransferase, alanine aminotransferase, γ-glutamyl transpeptidase and bilirubin in
serum, enhancing hepatic antioxidants. These observations suggest that the phenol rich
fraction has a potent antioxidant activity and prevents against CCl4 induced oxidative
damage in the liver.
Immunomodulating effects
Sea buckthorn strengthens and accelerates the immune response of the organism (Mic hel
et al. 2012). It accelerates regeneration of mucous membranes in the gastrointestinal tract,
such as in the stomach, the large intestine, the urinary tract, and the oral cavity (Chr istaki
2012). The sea buckthorn components most contributing to the immunomodulating effect
include avonoids such as leucocyanidin and catechin in the rst place and then also
isorhamnetin, quercetin, and quassin. These substances strengthen the immune system of
the organism and increase resistance to illnesses (Li and Be verid g e 2003).
The immunoprotective effect of sea buckthorn fruit against immunodepression caused by
T-2 toxin was tested in broiler chicks (Ram asamy et al. 2010). The immunoprotective effect
of sea buckthorn and glucomanane was evaluated with the help of humoral immune reaction
against NCD (Newcastle disease virus), LaSota strain vaccine (haemoagglutination test),
immunoglobulin concentrations, phagocyte index and DTH (delayed-type hypersensitivity)
reaction against 2, 4-dinitrourobenzene (DNFB) between days 25 and 28 of the trial.
A signicant decrease of non-specic immunity was observed in the group receiving T-2
toxin, shown by the phagocyte index, DTH reaction, haemagglutination inhibition (HI)
titre and total serum Ig, in comparison with the healthy control group. The group fed sea
buckthorn and glucomanane showed a signicant increase of the HI titre and total serum
Ig. These birds also showed a signicant increase of the DTH reaction and non-specic
immune response. Sea buckthorn itself protected against the immunosuppressive effect
of T-2 toxin, but sea buckthorn in combination with glucomanane showed an additional
protective effect against T-2 toxicity.
According to Lav inia et al. (2009) essential oils extracted from sea buckthorn berries
improve the immune response in broilers. The skin of broiler chicks fed sea buckthorn
showed a higher degree of lymph-follicular reaction (Lonar e et al. 2009). Sea buckthorn
oil supports tissue regeneration, with consequent positive effects on mucous membranes
such as in the stomach (Erkko la and Yang 2003), the duodenum (La vinia et al. 2009),
the urogenital tract, and the oral cavity (Erk kola and Yang 2003).
Effects suppressing the occurrence of gastric and duodenal ulcers
Hexane extract from sea buckthorn acts positively against indomethacin, stress, and
ethanol which contribute to the development of gastric ulcers (Khan et al. 2010). The
extract also shows positive effects in the treatment of duodenal ulcers (Li and Beve ridge
Huff et al. (2012) studied the efcacy of a commercial product containing the berries
and pulp of sea buckthorn in the therapy and prevention of gastric ulcers in horses. The
mean score of non-glandular gastric ulcers signicantly (P < 0.05) increased in all the
horses after an intermittent feed deprivation. The number of glandular ulcers and their
severity were signicantly lower in horses fed sea buckthorn enriched feed compared to the
control group. Sea buckthorn was not effective in the therapy/prevention of natural equine
non-glandular ulcers, however, the glandular ulcer score was signicantly lower in the sea
buckthorn fed group after feed deprivation. Sea buckthorn may therefore be used in the
prevention of glandular ulcers in horses in case of intermittent feeding.
Dermatological effects
Substances contained in sea buckthorn prevent dermatological diseases such as atopic
eczema (Khan et al. 2010). Creams containing sea buckthorn extracts support treatment of
skin disorders such as melanosis, chloasma, xeroderma, and recurrent dermatitis (Li and
Bev eridg e 2003; Barka t et al. 2010).
Burnt sheep were administered sea buckthorn seed oil and in 6, 14 and 21 days after
the injury, the wound blood ow and epithelization were determined. After 14 days the
percentage of epithelization in the areas treated with sea buckthorn was higher than in the
untreated areas. The epithelization time was signicantly shorter compared to the untreated
areas (Ito et al. 2014).
Platelet aggregation
Positive effects on platelets are mainly shown by avonoids and fatty acids. Their main
function is suppression of platelet aggregation induced by collagen, probably by inhibition
of the thyrosine kinase activity (Patel et al. 2012). Another substance signicantly
contributing to platelet aggregation is sitosterol (Joh ansso n et al. 2000).
Thanks to the abovementioned favourable effects on the health of organisms, in the
future sea buckthorn and its products may be expected to be widely used in therapy and
prevention both in humans and animals.
Role of sea buckthorn in human and animal nutrition
Interest in utilisation of sea buckthorn products has been increasing recently in the area
of human as well as animal nutrition. Thanks to the functional properties and unique taste
of the berries they can be used for production of juice, bonbons, jelly, jam, alcoholic and
non-alcoholic beverages or dairy product avours (Gao et al. 2000; Bal et al. 2011). Oils
from the seeds and pulp may be used as ingredients in food supplements such as jelly, plant
capsules, or oral uids (Yan g and Kalil o 2002). They are also used in cosmetic products
such as shampoo (B a l et al. 2011). Leaves are used for production of extracts, teas or
cosmetics (Gua n et al. 2005).
Sto bdan et al. (2013) report that sea buckthorn is a rich source of nutrients and bioactive
substances. Juice made from the berries is rich in sugar, organic acids, amino acids,
essential fatty acids, phytosterol, avonoids, vitamins, and minerals. The juice contains
24 minerals and 18 different amino acids. Total phytosterol content is × 4–20 higher than
in soybean oil. Seeds represent a valuable source of oil with high level of oleic acid and the
1 : 1 ratio of n-3 and n-6 fatty acids. The oil absorbs ultraviolet light and promotes healthy
skin. The leaves contain many nutrients and bioactive substances such as carotenoids, free
and esteried sterols, triterpenols, and isoprenols.
Sea buckthorn has long been used in animal nutrition as an additive to feed mixtures
for its favourable effects on animal health. A positive effect on the quality of farm animal
products has been observed. Ancient Greeks used leaves and twigs of sea buckthorn for
feeding animals, with a positive effect on the weight gain and shinning coat, especially in
horses (Sur yakum ar and Gupt a 2011).
Kau shal and Sharm a (2011) report that seed cakes and sea buckthorn leaves
are rich in proteins and minerals and represent a benecial animal feed. Similarly
Bis was et al. (2010) consider sea buckthorn leaves, seed and berry residues a suitable
feed for farm animals and poultry, mainly in dry and cold regions. In poultry, sea
buckthorn positively affected the egg production and body weight of laying hens
(Wang 1997).
Although information about potential applications of sea buckthorn and its products in
animal nutrition and its potential positive impact on animal product quality is available,
further research studies and knowledge in this area may signicantly contribute to the
extension of the sea buckthorn application area.

Sciences in Brno IGA 1/2014/FVHE.

... mg/100 g) (Arimboor et al., 2006), but lower than Chinese Sinensis (200-2500 mg/ 100 g) (Bal et al., 2011). For leaves, Krejcarová et al. (2015) reported that the vitamin C content of Czech H. rhamnoides levels up to 370 mg/100 g which is higher than the present result. This variation in Vitamin C is mainly due to genotype, cultivar, and ripening stage and time of harvest. ...
... The total tannin content in the leaves (80.1 ± 2.63 mg TAE/g) was two-fold higher than berries (42 ± 0.65 mg TAE/g) as shown in Table 1. The total tannin content in the leaves was in agreement with the report of 80 mg/g by Krejcarová et al. (2015) and the range between 59 and 350 mg/g by Stobdan et al. (2011) for Indian H. rhamnoides. However, it was 11-fold higher than the values reported by Kuhkheil et al. (2017) for Iranian H. rhamnoides which ranges from 1.99 to 5.74 mg/g. ...
... These compounds were more noticeable in acetone, methanol, and aqueous extracts followed by ethyl acetate, chloroform, and hexane extracts. A similar finding was reported by Ahmad and Ali (2013) in that many phytochemicals were presented in Krejcarová et al. (2015) methanol extracts. Qualitative phytochemical screening of leaves extracts was better than berries extracts. ...
The physico-chemical, polyphenols, antioxidant and antibacterial properties of berries and mixture of male and female leaves of Hippophae salicifolia were investigated. The mineral, vitamin C, sugar, total protein, and total tannin contents of the berries and the leaves were evaluated. Further, the extracts of berries and mixture of leaves samples obtained by successive solvent extraction were investigated for their polyphenols, antioxidant and antibacterial properties. Total phenolic content was highest in leaves-methanol extract (157.97 ± 2.09 mg GAE/g) followed by berries-aqueous extract (48.45 ± 1.94 mg GAE/g), while total flavonoid was predominant in leaves-acetone extract (75.64 ± 3.21 mg QE/g) and berries-methanol extract (28.93 ± 2.08 mg QE/g). Gallic acid, caffeic acid, and rutin were the major polyphenols confirmed by HPLC analysis. Berries-aqueous and leaves-methanol extracts showed excellent global antioxidant score. Best antibacterial activity was observed by methanol extracts against eight different strains. Overall, the leaves and berries of Hippophae salicifolia collected from Northeast India exhibited good antioxidant and antibacterial activity and can be utilized by food and pharmaceutical sectors.

... Hippophae rhamnoeides, also known as sea buckthorn, is a deciduous and resistant shrub with yellow and orange berries cultivated mainly in Europe and Asia [16]. Its fruits possess a high nutritional value, being rich in antioxidants (e.g., polyphenols, vitamins C and E, carotenoids) [17,18] and beneficial fatty acids [19]; however, recent studies also exhibit its important medicinal and therapeutic potential as well [20], including several bioactivities (antibacterial, reduce of hypertension and prevention of cardiovascular diseases, etc.) [21]. Hippophae sp. is a plant with an important economic value, since not only the berries, but also the roots, the leaves, and seed can be used as a source for a range of products [22]. ...

Agricultural pruning residues represent an emerging type of by-products very poorly attended so far, usually incinerated in the open fields where they are produced, this way provoking negative environmental effects and facilitating the loss of valuable resources. The present study examines the potential exploitation of Hippophae rhamnoeides (sea buckthorn) pruning, a poorly exploited substrate, the fruits of which have been widely used for dietary supplement production, and thus its cultivation has significantly grown. The study conducted dilute acid pretreatment followed by anaerobic digestion towards the production of biogas (methane). Initially, a parametric analysis was carried out to establish the optimum pretreatment conditions, enabling partially hemicellulose depolymerization from the original feedstock. It was found that the parameters of solids loading, and duration of pretreatment had a positive impact on hydrolysis, leading to maximum overall sugars yield of 19.00 ± 2.14% (per g of biomass) under 30% loading (w/v), 121 °C, 2% H3PO4, and 120-min hydrolysis conditions. However, higher temperature and acid concentration were not equally effective in enhancing hydrolysis yields under the conditions tested. Next, study of acid pretreatment with response surface methodology (RSM) and biochemical methane potential (BMP) assays were employed to evaluate the potential of the treated feedstock for biogas production. As a result of the high lignin content of the substrate, as well as possible toxicity and inhibition phenomena due to the acid hydrolysis conditions, the maximum BMP yield obtained from the tests was equal to the yield of the untreated substrate (225.30 mL CH4/g VSadded). Concerning the tested factors, even if none of them alone exhibited statistically significant differences in the results, the combination of acid concentration and time seems to have considerably affected the obtained yields. Graphical abstract
... Sea buckthorn (Hippophae rhamnoides L.) has been used for several years in different forms, mainly in human nutrition, as a health supplement, due to the content of bioactive substances. It has been examined in recent years as a supplement to animal nutrition (Krejcarová et al., 2015). The reason for this is the assumption that the products of animals fed on Sea buckthorn will be enriched with valuable bioactive substances. ...

Effect of partial replacing of wheat by sea buckthorn (Hippophae rhamnoides L.) fruit residues in broiler diets on performance and skin pigmentation
The effects of ultrahigh-temperature sterilization (UHT) on the volatile components and chemical composition of sea buckthorn pulp (SBP) were evaluated firstly. UHT had significant effects on the volatiles of SBP (mainly occurring at 140 °C for 2 s and 4 s), in which 140 °C for 2 s resulted in a decrease of 3.48% and 14.60% in total volatiles and esters, and an increase of 6.73% in alcohols, while alcohols contents sharply decreased by 6.90% at 140 °C for 4 s. Moreover, 140 °C for 2 s and 4 s decreased the amino acid content by 35.39% and 29.75%, respectively, while UHT significantly promoted the increase of fatty acids, but only a small increase at 140 °C for 4 s. The speculation is that a large number of volatiles were formed during the 140 °C for 2 s and 4 s, mainly from amino acid reactions and lipid oxidation.
Sea buckthorn (Hippophae rhamnoides L.) is a unique and valuable plant and has recently gained worldwide attention mainly for its medicinal and nutritional potential. It is a thorny bush with yellow-orange pearl shaped fruits and has a high content of vitamins, minerals, natural antioxidants and omega-3,6 fatty acids.Doses of 2 mg/ml, 4 mg/ml and 6 mg/mlof aqueous extract of plant berry powder were evaluated against Gram positive and Gram negative microbes by usingdisc diffusion and agar well diffusion method. The zone of inhibition was compared with the standard drugs vancomycin andKanamycin(30 µg/ml). It was concluded that the aqueous extract of berry powder has antibacterial activity, which may be used to preventvarious diseases and can be incorporated in human and animal diet.

Plants have served for centuries as sources of compounds useful for human health such as antioxidant, anti-diabetic and antitumor agents. They are also rich in nutrients that improve the human diet. Growing demands for these compounds make it important to seek new sources for them. Hippophae rhamnoides L. is known as a plant with health-promoting properties. In this study we investigated the chemical composition and biological properties of bioactive components of ethanol extracts from leaves and twigs of H. rhamnoides L. Chemical components such as the total content of phenolic compounds, vitamins and amino acids and the antioxidant activities of these compounds in cellular and cell-free systems were assessed. The results suggest that the studied extracts are rich in bioactive compounds with potent antioxidant properties. Cytotoxicity and hemotoxicity assays showed that the extracts had low toxicity on human cells over the range of concentrations tested. Interaction with human serum albumin was investigated and conformational changes were observed. Our results indicate that leaf and twig extracts of H. rhamnoides L. should be considered as a non-toxic source of bioactive compounds which may be of interest to the food, pharmaceutical and cosmetic industries.

The present study presents the use of photochemiluminescence assay (PCL) and 2,2 diphenyl-1-picryl-hydrazyl (DPPH), 2,2′-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid (ABTS), the ferric reducing antioxidant power (FRAP), and cupric ion reducing antioxidant capacity (CUPRAC) methods for the measurement of lipid-soluble antioxidant capacity (ACL) of 14 different byproducts obtained from the vegetable oil industry (flour, meals, and groats). The research showed that the analyzed samples contain significant amounts of phenolic compounds between 1.54 and 74.85 mg gallic acid per gram of byproduct. Grape seed flour extract had the highest content of total phenolic compounds, 74.85 mg GAE/g, while the lowest level was obtained for the sunflower groats, 1.54 mg GAE/g. DPPH values varied between 7.58 and 7182.53 mg Trolox/g of byproduct, and the highest antioxidant capacity corresponded to the grape seed flour (7182.53 mg Trolox/g), followed by walnut flour (1257.49 mg Trolox/g) and rapeseed meals (647.29 mg Trolox/g). Values of ABTS assay of analyzed samples were between 0 and 3500.52 mg Trolox/g of byproduct. Grape seed flour had the highest value of ABTS (3500.52 mg Trolox/g), followed by walnut flower (1423.98) and sea buckthorn flour (419.46). The highest values for FRAP method were represented by grape seed flour (4716.75 mg Trolox/g), followed by sunflower meals (1350.86 mg Trolox/g) and rapeseed flour (1034.92 mg Trolox/g). For CUPRAC assay, grape seed flour (5936.76 mg Trolox/g) and walnut flour (1202.75 mg Trolox/g) showed the highest antioxidant activity. To assess which method of determining antioxidant activity is most appropriate for the byproducts analyzed, relative antioxidant capacity index (RACI) was calculated. Depending on the RACI value of the analyzed byproducts, the rank of antioxidant capacity ranged from −209.46 (walnut flour) to 184.20 (grape seed flour). The most sensitive methods in developing RACI were FRAP (r = 0.5795) and DPPH (r = 0.5766), followed by CUPRAC (r = 0.5578) and ABTS (r = 0.4449), respectively. Strong positive correlations between the antioxidant capacity of lipid-soluble compounds measured by PCL and other methods used for determining antioxidant activity were found (r > 0.9). Analyses have shown that the different types of byproducts obtained from the vegetable oil industry have a high antioxidant activity rich in phenolic compounds, and thus their use in bakery products can improve their nutritional quality.
The development of resource-saving technologies for obtaining pure sea buckthorn oil and its compositions with other vegetable oils from dried crushed sea buckthorn cake is an urgent task. Sea buckthorn oil and its mixtures are obtained by extraction and simultaneous heat exposure, electrophysical methods of the process intensifying being considered in this case. Currently, there are no reliable data on the thermo- and electrophysical properties of dried crushed sea buckthorn cake at atmospheric pressure in the literature. Therefore, experimental studies of the thermo- and electrophysical properties of dried crushed sea buckthorn cake in a wide range of changes in state parameters are of great importance for solving theoretical and practical problems. The nature of the change in the specific heat, thermal conductivity and thermal diffusivity in the temperature range 20 ... 80 ° C and humidity 7.0 ... 17.5% was determined to be linear. In this case, the specific heat and the coefficient of thermal conductivity increase with increasing temperature while the coefficient of thermal diffusivity decreases. The nonlinear dependence of the dielectric loss coefficient on moisture was found to be due to a variety of forms of moisture binding in the sea buckthorn cake particles. It is obvious that with an increase in the cake temperature and humidity, the dielectric loss coefficient monotonically nonlinearly increases in the range of 0.46 ... 9.72. Empirical equations that make it possible to reliably determine the value of the specific mass heat capacity, thermal conductivity coefficients, thermal diffusivity and dielectric losses of dried crushed sea buckthorn cake from temperature and humidity in the range of 7.0 ... 17% with respect to absolutely dry matter were obtained as a result of studies of thermo- and electrophysical properties..
Hippophae rhamnoides L. (Elaeagnaceae Juss.) is a valuable multipurpose plant with vast secondary area which covers many regions of Europe, Asia and North America. When introduced in new places, it often exhibit invasive properties. In Primorsky Krai (Russian Federation) sea buckthorn is detected in 139 settlements where it grows mainly in household plots and is used as medicinal and food plant. Easily forming numerous root suckers, sea buckthorn often create more or less dense thickets. Six places were found in Primorsky Krai where Hippophae rhamnoides actively reproduces vegetatively. These places are disturbed areas and sea buckthorn cultivation plots. The plant don’t penetrate into natural phytocoenoses which allows regarded it as epecophyte.

Hippophae rhamnoides, also known as sea buckthorn is an ancient plant with modern virtues, due to its nutritional and medicinal value. Sea buckthorn is a spiny bush with long and narrow leaves, and orange-yellow berries. It is cold resistant, and native to Europe and Asia. All parts of Hippophae e.g. berries, leaves, and seed or pulp oils contain many bioactive compounds. They are a rich source of natural antioxidants such as ascorbic acid, tocopherols, carotenoids, fla-vonoids, while they contain proteins, vitamins (especially vitamin C), minerals, lipids (mainly unsaturated fatty acids), sugars, organic acids and phytosterols. Animal and human studies suggest that sea buckthorn may have various beneficial effects: cardioprotective, anti-atherogenic, antioxidant, anti-cancer, immunomodulatory, anti-bacterial, antiviral, wound healing and anti-inflammatory. Hippophae could also be used in human and animal nutrition. Therefore, it would be worthwhile to perform more scientific research on this medicinal plant and to promote its large-scale utilization.

This study presents nutritional and antimicrobial characteristics of seabuckthorn seed oil, extracted from berries of Hippophae salicifolia (4.3-4.9%) and H. rhamnoides (4.75-5.25%). Physicochemical analysis of seed oil gave: acid value, 4.0-4.7 mg KOH/g; saponification value, 184.3-230.2 mg KOH/g; peroxide value, 17.5-18.3 meq/kg; and unsaponifiable matter, 0.60-0.78%. The oil contained oleic acid (31.8-37.0%), linoleic acid (25.8-27.9%) and linolenic acid (14.1-17.8%), and thus showed predominance of unsaturated fatty acids (82.6-83.5% w/w) comprising of both polyunsaturated fatty acids (39.9-45.8% w/w) and monounsaturated fatty acids (36.9-43.6% w/w). Seeds of both species contained vitamin E (27.0-30.0 μg/g). Seed oil exhibited good antimicrobial property (growth inhibition zone diam, 4.0 mm) against Escherichia coli. Thus, owing to high content of linolenic acid and vitamin E and good antimicrobial property, seed oil can be exploited in pharmaceutical, cosmetic and nutraceutical preparations. Seed cake was rich in proteins and minerals and can be used as animal feed.

American foulbrood is a dangerous world-wide spread disease of honey bees caused by the Paenibacillus larvae bacterium. Antibiotic treatments are less effective and leave residues in bee products. It is therefore necessary to find an alternative, especially using natural ingredients such as plant essential oils, probiotics, fatty or organic acids. Two strains of P. larvae were used for this study: CCM 4488, a strain from the Czech collection of micro-organisms and a Slovak field strain which was isolated from infected bee combs and characterized on the basis of biochemical properties. Plant essential oils of sage (Salvia officinalis), anise (Pimpinella anisum), oregano (Origanum vulgare), caraway (Carum carvi), thyme (Thymus vulgaris), rosemary (Rosmarinum officinalis), clove (Syzygium aromaticum), camomile (Chamomilla recutita) and fennel (Foeniculum vulgare) were used for the testing of the inhibitory activity against P. larvae. Essential oils at amounts of 5 μl and 10 μl were applied to sterile discs on MYPGP agar; inhibition zone diameters were measured after 24-h incubation at 37 °C. The strongest inhibitory activity against both P. larvae strains was noted in case of the essential oils from oregano, thyme and clove; essential oils from camomile, rosemary and fennel showed no or weak antibacterial activity. Medium strong inhibition activity was recorded in case of previously untested essential oil from Carum carvi. There was a difference in sensitivity of both tested strains to essential oils. Our study confirmed that some essential oils can be used in the prevention of American foulbrood but further experiments aimed at their influence on physiological intestinal microflora of honey bees must be performed.

Hippophae rhamnoides L. (Elaeagnaceae) also known as seabuckthorn, is a thorny, deciduous, temperate bush plant native to European and Asian countries. In India, it is widely distributed at high altitude, cold arid condition of Ladakh (Leh and Kargil), Himachal Pradesh, Sikkim and Arunachal Pradesh. H. rhamnoides has been used for the treatment of several diseases in traditional medicine in various countries throughout world. In Ladakh, the Sowa Rigpa system (Amchi System of medicine) has been using the plant parts in different herbal formulations. However, more scientific data is needed to support the various health claims. The various in vivo study of seabuckthorn oil reported to have anti-inflammatory, antioxidant, antimicrobial, anti-ulcer properties and hepatoprotective. Seabuckthorn oil is a unique source of high valued oils emphasizing its potential as a dietary and medicinal supplement and has become noted for its generally high levels of nutritionally and medicinally important components. The major unsaturated fatty acids were linolenic acid (omega-3) (20-23%), linoleic acid (omega-6) (40-43%), oleic acid (omega-9) (19-22%) and palmitoleic acid (1-3%) while the major saturated fatty acid contents were palmitic acid (7-9%), stearic acid (3-4%) in seed oil. Seabuckthorn pulp oil contains approximately 65% combined of the monounsaturated fatty acid and the saturated fatty acid. Both the seed and pulp oils are rich in Vitamin-E and β-Sitosterol. In addition, the pulp oil contains especially high levels of carotenoids. This ancient plant with its powerful and healing synergies has much to contribute to the livelihoods of high mountain people by utilizing this kind of hidden treasure of the Himalayas. In this review discusses on traditional use, phy to chemistry and pharmacological data of the seabuckthorn oil.
It was previously reported that essential oils from aromatic plants have an antimicrobial activity against many bacterial pathogens [13]. We have conducted an in vivo experiment to study the effect of some aromatic plants and in particular to investigate the effect of oils extracted from these plants at the immune level and duodenal morphology. During the experiment 90 chicken broilers were divided in three experimental groups: control group (C), group 1 (G1) and group 2 (G2). The chicken broilers from group G1 had received feed with 0.05% incorporated oils extracted from savory (Satureja hortenis), mint (Mentha piperita) and sea-buckthorn (Hippophae rhamnoides). Group G2 received a premix of plants (savory, mint and sea-buckthorn) during daily feeding. The control group (C) received normal feed with no supplements. The amount of lysozyme detected at group G1 was doubled (28.55 mcg/cm 3) compared to G2 (13.2 mcg/cm 3) and the control (11.42 mcg/cm 3). The incorporation of extracted oils in food resulted in a powerful stimulation of intestinal mucous membrane, manifested by development of intestinal villi, the hypertrophy of villi, hyperplasic hypertrophy of capillary network and the stimulation of leukocytes infiltration. The muscular hypertrophic processes and leukocyte infiltration are visible in the endomesium and perimesium of the muscular tunic. Microscopical images of the G2 group taken from the duodenum sections suggest the stimulation of angiogenesis. The processes are however of smaller intensity in the G1 group. This work shows that essential oils extracted from plants improve the immune response and also are able to cause changes of the duodenal mucosa with beneficial effects for the animal.
The present study undertaken to study the cellular immune response in seabuckihorn fed White Leghorn broiler chickens which was evaluated by OTH reaction. Both the SBT fed groups showed higher DTH reaction recorded at 24 hr post challenge as compared to control group. Histopathological investigation revealed higher degree of lymphofollicular reaction in the challenged skin of birds from both SBT fed groups.
A study is performed on sea buckthorn oil and health of mucous membranes. Mucous membranes are constantly under the challenges of genetic deficiencies, disease, stress, ageing, side effects of medical treatments and environmental factors such as air and water pollutes. It is reported that clinical trials with larger number of patients are justified to more accurately pinpoint the conditions which may benefit from treatment with sea buckthorn oils.
Hippophae rhamnoides Linn., commonly known as sea buckthorn (family: Elaeagnaceae), grows wild in Asia and Europe. As one kind of Chinese traditional medicine, H. rhamnoides Linn. berry was effective in treating wounds, inflammation, mucous-membrane-related disorders and diseases such as cough, sputum, cancer and bacterial problem. In diabetes, H. rhamnoides Linn. affected not only the lowering of the blood sugar including fasting blood glucose and 2 h postprandial blood glucose, but also in treating the complications. H. rhamnoides Linn. had been shown to be effective in cell cultures, animal studies, and clinical practice. Although, H. rhamnoides Linn. had been shown to have positive effects in relieving symptoms, such as fatigue, dry mouth and dry eye in non-diabetic disease, whether it has the therapeutic effect on diabetes symptoms was still unclear. Studies have to be conducted to test and verify the effect of H. rhamnoides Linn. on symptoms in diabetes patients. On the whole, H. rhamnoides Linn. is a candidate for complementary diabetes therapy.
