Foeniculum vulgare Mill commonly called fennel has been used in traditional medicine for a wide range of ailments related
to digestive, endocrine, reproductive, and respiratory systems. Additionally, it is also used as a galactagogue agent for lactating
mothers. e review aims to gather the fragmented information available in the literature regarding morphology, ethnomedicinal
applications, phytochemistry, pharmacology, and toxicology of Foeniculum vulgare. It also compiles available scientic evidence
for the ethnobotanical claims and to identify gaps required to be lled by future research. Findings based on their traditional
uses and scientic evaluation indicates that Foeniculum vulgare remains to be the most widely used herbal plant. It has been used
for more than forty types of disorders. Phytochemical studies have shown the presence of numerous valuable compounds, such
as volatile compounds, avonoids, phenolic compounds, fatty acids, and amino acids. Compiled data indicate their ecacy in
several in vitro and in vivo pharmacological properties such as antimicrobial, antiviral, anti-inammatory, antimutagenic, antinoci-
ceptive, antipyretic, antispasmodic, antithrombotic, apoptotic, cardiovascular, chemomodulatory, antitumor, hepatoprotective,
hypoglycemic, hypolipidemic, and memory enhancing property. Foeniculum vulgare has emerged as a good source of traditional
medicine and it provides a noteworthy basis in pharmaceutical biology for the development/formulation of new drugs and future
clinical uses.
1. Introduction
Foeniculum vulgare is the oldest valid name within the genus
Foeniculum for the plant designated by Karsten as Foeniculum
Foeniculutn. However, according to the international rules
of nomenclature, the binomial name Foeniculum vulgare was
not validly published by Hill in his reference []forthereason
that he did not consistently adopt the binomial system of
nomenclature. In accordance with the international rules as
adopted at Cambridge, the name Foeniculum vulgare must
be accredited to Philip Miller, who rst validly published
it in the eighth edition of his “Gardeners Dictionary” in
.Fromthenon,thenameofthisplantiswrittenas
Foeniculum vulgare Mill. It is a medicinal plant belonging
totheUmbelliferae(Apiaceae)family,knownandusedby
humans since antiquity, due to its avor. It was cultivated in
almost every country []. It is universally known as Fennel
and is known by more than names (Tabl e ). It is a
traditional and popular herb with a long history of use as
a medicine. A series of studies showed that F. vu l gare eec-
tively controls numerous infectious disorders of bacterial,
fungal, viral, mycobacterium, and protozoal origin [–]. It
has antioxidant, antitumor, chemopreventive, cytoprotective,
hepatoprotective, hypoglycemic, and oestrogenic activities
[–]. Some of the publications stated that F. v u lgare has
a special kind of memory-enhancing eect and can reduce
stress []. Animal experiments and limited clinical trials
suggest that chronic use of F. v u l gare is not harmful. Fennel
maybe consumed daily, in the raw form as salads and snacks,
stewed, boiled, grilled, or baked in several dishes and even
used in the preparation of herbal teas or spirits. A diet
with desired quantity of fennel could bring potential health

increased interests in improvement of agricultural yield of
fennel due to its medicinal properties and essential oil content
has encouraged cultivation of the plant on large scale.
Research on F. vulg a r e with current technology has been
conductedallovertheworld.Alltheavailableliteratureon
F. vu l g are was compiled from electronic databases such as
Academic Journals (including high impact, nonimpact, and
nonindexed journals), Ethnobotany, Google Scholar, Scopus

a total of claims appeared in the literature on various
aspects of F. v u lga r e . It is important to note that about
% of reports ( articles) were collected from recent three
years, that is, to (Figure ). Some of the earlier
published reviews of this plant included medicinal properties
and phytochemistry [–], but few of them appear in all
these reviews. However, there is a need for an inclusive
review that bridges the gaps between traditional uses of
fennel and its in vitro studies. e present review attempts
to collate the available information on the botany, nation-
wise common vernacular names, cultivation (propagation),
nutritive value, and traditional/contemporary as well as allied
applications, phytochemistry, pharmacology, and toxicity of
F. vu l g are. We hope that this review may provide scientic
basis that explains the ethnophytopharmacological role of
F. vu l g are in order to facilitate and guide future research.
In particular, we aimed to answer the following questions.
() What information is available on the traditional uses,
botany, phytochemistry, and toxicity of F. vul g are?()What
pharmacological studies were performed on this plant and
how do they validate its traditional uses? () What is the
future for F. vu l g are?

1.2. Botanical Description. Fennel is an ancient seasonal herb.
e fennel plant originated in the southern Mediterranean
region and through naturalization and cultivation it grows
wild throughout the Northern, Eastern, and Western hemi-
spheres, specically in Asia, North America, and Europe.
It is cultivated in elds and also grows wild. e herb was
well-known to the ancient Egyptians, Romans, Indians, and
Chinese. e Romans grew it for its aromatic seeds and
the edible eshy shoots are still a very common vegetable
in southern Italy []. Emperor Charlemagne was known
to have encouraged its cultivation in Central Europe. It is
an indispensable ingredient in modern French and Italian
cooking. All parts of the plant are aromatic and can be used
in many ways.

us, as a typical, seasonal fresh fruit, fennels are an
important constituent of the regional diet of Europe and other
regions. Dierent varieties of fennel parts are widely used in
many of the cooking dishes all over world (Table ). Shoots,
tender leaves, and stems are chewed and sucked due to their
exquisite aniseed avor. All these parts are also commonly
used as vegetables. ey are added raw to salads, stewed
with beans and chickpeas, used to stu sh for grilling,
and placed in soups and bread bouillons. Besides seasoning,
fennel is used to preserve food. Flowering stems, sugar, and
honey macerating in brandy produce a highly valorized spirit.
Herbal teas prepared with fresh tender or dried owering
stems are consumed chilled or hot, depending on the season.
F. vu l g are is famous for its essential oil. e characteristic
anise odour of F. vu l g are, which is due to its essential oil,
makes it an excellent avoring agent in baked goods, meat
and sh dishes, ice-cream, and alcoholic beverages. e
culinary uses of fennel are so diverse/widespread that it has
been exported from country to country for centuries [].
2. Traditional and Contemporary Uses
Foeniculum vulgare has been extensively used in traditional
medicine for a wide range of ailments. Fennel is used in
various traditional systems of medicine like in the Ayurveda,
Unani, Siddha, in the Indian, and Iranian traditional systems
of alternative and balancing medicine []. Its stem, fruit,
leaves, seeds, and whole plant itself are medicinally used
in dierent forms in the treatment of a variety of diseased
conditions. e preparation methods, uses, and application
of F. vu l g are are well documented in the common ethnob-
otanical literature [–]. Tab l e lists the ethnomedicinal
uses of F. vu l g are for dierent types of ailments in Bolivia,
Brazil, Ecuador, Ethiopia, India, Iran, Italy, Jordan, Mexico,
Pakistan,Portugal,Serbia,SouthAfrica,Spain,Turkey,and
USA [,,–]. It is used to treat simple ailments (e.g.,
cough/cold, cuts) to very complicated ailments (e.g., kidney
ailments, cancer). It also has a wide range of veterinary uses
([,]seeTable).F. v ul g are is used in many parts of the
worldforthetreatmentofanumberofdiseases,forexample,

rhoea, liver pain, mouth ulcer, and stomachache (Tab l e ).
In addition to its medicinal uses, aerial parts, namely,
leaf, stem, and fruit/seed of F. vu l g are , are extensively used as
galactagogues not only for increasing the quantity and quality
of milk but also for improving the milk ow of breastfeeding
mothers [,,,]. From ancient times, fennel seeds
have been used as an ingredient for removing any foul smell
of the mouth []. e natural light green dye obtained from
leaves is used in cosmetics, for coloring of textiles/wooden
materials and as food colorant. Yellow and brown color dyes
are obtained by combining the owers and leaves of fennel
[].InPortugal,Italy,Spain,andIndia,thestem,fruit,
leaves, seeds, and whole plant are used as a vegetable [,,
,,]. Sugar coated and uncoated fennel seeds are used
in mukhwas (Mouth freshener) (Figure (b)). In many parts
of India and Pakistan, roasted fennel seeds are consumed as
mukhwas (Mouth freshener). Mukhwasisacolorfulaer-
meal mouth freshener or digestive aid. It can be made of
various seeds and nuts but oen found with fennel seeds,
anise seeds, coconut, and sesame seeds. ey are sweet in
avor and highly aromatic due to the presence of sugar and
the addition of various essential oils. e seeds can be savory,
coated in sugar, and brightly colored.

fennels. e hexane extracts of fennel were analyzed by GC-
MS and compounds were identied from these extracts;
the major compounds were identied as ,-benzenediol, -
methoxycyclohexene, o-cymene, sorbic acid, -hydroxy--
methyl--cyclopenten--one, estragole, limonene--ol, and
-methyl--cyclopenten--one []. Diao et al. [] identify
a total of components by GC and GC/MS from fennel
oil, representing .% of the total amount. Trans-Anethole
(.%), a phenylpropanoid, was found to be the main
component, followed by estragole (.%) with limonene
(.%), fenchone (.%), and others as minor components.
3.2. Flavonoids. Flavonoids are generally considered as an
important category of antioxidants in the human diet.
Flavonoids are abundant in the plants of Apiaceae family. It
has been reported that the presence of avonol glycosides
in fennel species is related to its morphological hetero-
geneity and variation. Total avonoid content of hydroal-
coholicextractsisabout12.3 ± 0.18mg/g. Flavonoids like
eriodictyol--rutinoside, quercetin--rutinoside, and ros-
marinicacidhavebeenisolatedfromF. v u lga r e [].
Amongst the avonoids present in F. vu l g are,themostpreva-
lent are quercetin--glucuronide, isoquercitrin, quercetin-
-arabinoside, kaempferol--glucuronide and kaempferol--
arabinoside, and isorhamnetin glucoside []. Quercetin--
O-galactoside, kaempferol--O-rutinoside, and kaempferol-
-O-glucoside have also been reported to occur in the aque-
ous extract of F. vu l g are []. e avonoids like isorham-
netin -O-𝛼-rhamnoside, quercetin, and kaempferol were
also isolated from the ethyl acetate extract, whereas quercetin
-O-rutinoside, kaempferol -O-rutinoside, and quercetin
-O-𝛽-glucoside were isolated from the methanol extract.
ese avonoids exhibit remarkable antinociceptive and anti-
inammatoryactivity[]. Further, quercetin, rutin, and
isoquercitrinwerereportedtohavetheimmunomodulatory
activities [].
3.3. Phenolic Compounds. ere has been a growing interest
in phenolic components of fruits and vegetables, which may
promote human health or lower the risk of disease. Aqueous
extract of fennel fruits are rich in phenolic compounds.
Many of them have antioxidant activities and hepatopro-
tective properties. e phenolic compounds present in F.
vulgare are considered to be associated with the prevention
of diseases possibly induced by oxidative stress such as
cardiovascular diseases, cancer, and inammation. ese
phenolic compounds have received tremendous attention
among nutritionists, food scientists, and consumers due
to their role in human health. Fennel has been reported
to contain hydroxyl cinnamic acid derivatives, avonoid
glycosides, and avonoid aglycones []. e methanolic
extract of fennel seeds contains rosmarinic acid, chlorogenic
acids as major phenolic compounds (.% and .%, resp.),
and quercetin and apigenin as the major avonoids (.% and
.%, resp.). Also, the total phenolic compounds in fennel
methanol extract were higher than the avonoid compounds
[]. F. vu l g are has been reported to contain phenolic acids
like -O-caeoylquinic acid, -O-caeoylquinic acid, -O-
caeoylquinic acid, ,-O-di-caeoylquinic acid, ,-O-di-
caeoylquinic acid, and ,-O-di-caeoylquinic acid [].
TwocompoundsAandBwereisolatedandcharacter-
ized for the rst time from the wild fennel and identi-
ed as ,-dihydroxyphenethylalchohol--O-caeoyl-𝛽-D-
glucopyranoside and ,-binaringenin, respectively. e
total phenolic and avonoid contents of wild fennel (.% and
.% resp.) were less as compared to cultivated fennel (.%
and .%, resp.) [].
4. Pharmacological Activities
Foeniculum vulgare is ocially noted in Ay u r vedic Pharma-
copoeia as an important part of polyherbal formulations in
the treatment of dierent diseases and disorders. A number
of biological-pharmacological studies have been undertaken
to evaluate the indigenous uses of F. vu l g are. Few extracts of F.
vulgare andisolatedcompoundshavebeenevaluatedforsev-
eral activities, namely, antiaging, antiallergic, anticolitic, anti-
hirsutism, anti-inammatory, antimicrobial and antiviral,
antimutagenic, antinociceptive, antipyretic, antispasmodic,
