ABSTRACT
The whole world facing COVID-19 pandemic, so there has been a lot of interest in ways to boosting our
immune system, and thus build a first line of defence against the deadly virus. Since ancient times,
medicinal plants, herbs and spices were well known for their medicinal properties. Therefore, the medicinal
plants and herbs playing a critical role to boosting our immunity during the COVID-19 pandemic. it is also
very important to consume supplements in the form of immune nutrients such as vitamin A, C, E, D, B-
complex, Zinc and copper that will support your body to fight against the pathogens. This paper presents an
analysis of popular immune-boosting medicinal plants and herbs.
Keywords: Medicinal herbs, Medicinal plants, COVID-19, Coronavirus, Immunity, SARS-CoV-2,
Immunity booster.
INTRODUCTION
Covid-19 attacks people with low immune systems and people especially people of under and over ages.
The immune system is built on beneficial live bacteria that lives in the gut which protect the human body
from various diseases. When the immune system response is low, weak, or damaged, it becomes an open
invitation for infections such as coronavirus or other diseases like diabetes, heart disease, or cancer.1 In this
article we discussing about various medicinally important plants and herbs which can serve as boon in the
fight against COVID-19 e.g. Garlic (Allium sativum), Margosa neem (Azadirachta indica), Tulsi (Ocimum
sanctum), Giloy (Tinospora Cordifolia), clove (Syzygium aromaticum), ginseng (Panaxquinquefolius L.),
Betel vine (Piper betel), Black paper (Piper nigrum), Black cumin (Black cumin L.), Ashwagandha
(Withania somnifera), Licorice astragalus (Astragalus glycyphyllos), turmeric (Curcuma domestica),
elderberry (Sambucus nigra), Giloy (Tinospora Cordifolia)etc. These plants are known to be rich in
antioxidants, vitamins, proteins, carbohydrates, dietary fibers, amino acids, minerals, steroids, alkaloids,
antiviral, antibacterial phytochemicals which will help in rejuvenating the immune system and also helps in

IMMUNITY
The immune system protects our body from diseases and infections (invading pathogenic microorganisms)
and cancer. It's the bodily system that produces the immune response to defend your body from foreign
substances, cells, and tissues. The immune system includes various parts of the body including the thymus,
spleen, lymph nodes, special deposits of lymphoid tissue (such as those in the gastrointestinal tract and
bone marrow), macrophages, lymphocytes including the B cells and T cells, and antibodies.1 Immunity, the
state of protection from infectious disease has both a less specific or innate and a more specific or adaptive
component. Therefore, the immune system has two components: innate and adaptive immunity. The innate
immunity is present in all metazoans, while the adaptive immunity only occurs in vertebrates.
Innate Immunity
This provides the first line of defence against infection. It is a rapid response (minutes); it is not specific to
a particular pathogen. It has no memory and does not confer long-lasting immunity to the host. It has 4
main components and is found in all classes of plant and animal life.2 The innate immune system is made
of defences against infection that can be activated immediately once a pathogen attacks. The innate immune
system is essentially made up of barriers that aim to keep viruses, bacteria, parasites, and other foreign
particles out of your body or limit their ability to spread and move throughout the body. The innate immune
system includes:
Physical Barriers
Such as skin, the gastrointestinal tract, the respiratory tract, the nasopharynx, cilia, eyelashes and other
body hair.

Defense Mechanisms
Such as secretions, mucous, bile, gastric acid, saliva, tears, and sweat.
General Immune Responses
such as inflammation, complement, and non-specific cellular responses. The inflammatory response
actively brings immune cells to the site of an infection by increasing blood flow to the area. Complement is
an immune response that marks pathogens for destruction and makes holes in the cell membrane of the
pathogen.3
Adaptive Immunity
This provides a specific immune response directed at an invading pathogen. Following exposure to a
foreign organism there is an initial effector response that eliminates or neutralizes a pathogen. Later re-
exposure to the same foreign organism induces a memory response with a more rapid immune reaction that
eliminates the pathogen and prevents disease. This response is found only in vertebrates.4
Adaptive immunity is an immunity that occurs after exposure to an antigen either from a pathogen or a
vaccination. This part of the immune system is activated when the innate immune response is insufficient to
control an infection. In fact, without information from the innate immune system, the adaptive response
could not be mobilized. There are two types of adaptive responses: the cell-mediated immune response,
which is carried out by T cells, and the humoral immune response, which is controlled by activated B cells
and antibodies. Activated T cells and B cells that are specific to molecular structures on the pathogen
proliferate and attack the invading pathogen. Their attack can kill pathogens directly or secrete antibodies
that enhance the phagocytosis of pathogens and disrupt the infection. Adaptive immunity also involves a
memory to provide the host with long-term protection from reinfection with the same type of pathogen; on
re-exposure, this memory will facilitate an efficient and quick response.5
Natural immunity
Antibodies generated due to a normal infection. Includes antibodies provided by mother through their
colostrum, the initial breastmilk. Only protects for short time, but when infant is most vulnerable.
Artificial immunity
Antibodies generated by receiving antigen in a vaccine/serum rather than a normal infection. Generally
does not last as long as when generate antibodies from a natural infection.
Active immunity
Immunity derived from antibodies generated by own body. Generated in response to normal infection or in
response to vaccine antigens.
Passive immunity
Immunity derived from antibodies from another body, such as given through mother's milk or artificial
means (antivenom antibodies). Generally does not last as long as active immunity as antibodies are not
supplied by the body. The diagram below summarizes these divisions of immunity.6-7

Medicinal plants are considered as rich resources of ingredients which can be used in drug development
pharmacopoeial, non- pharmacopoeial or synthetic drugs. There are many benefits of Herbal Medicine like
easier to obtain than prescription medicine, Stabilizes hormones and metabolism, Natural healing, Strength
in immune system. According to the World Health Organisation, around 80% of the world’s population
uses herbal medicines for primary health care, particularly across Europe and South Asia. Research
indicates that many of these herbs not only have anti-inflammatory properties, they also help build up the
body’s natural immunity. And unlike allopathic medicines like antibiotics, which can have serious side
effects, most of these herbs and spices are relatively safe.
Medicinal Plants and Herbs
Sambucus nigra (Elderberry)
Elderberry, scientific name Sambucus nigra, is an intense purple berry and widely present in Europe and
Western Asia. It has been in use for many years due to its enormous health benefits. Chemically it is rich in
polyphenolic compound (Anthocyanins, Flavonols, Phenolic acid), terpenes, carbohydrate (mainly glucose
and fructose), citric acid, malic acid and lectins and other essential nutrients.2 Liquid elderberry extract is
characterized by antiviral action in vitro against influenza, as well as respiratory bacterial pathogens. There
is preclinical evidence that elderberry (Sambucus nigra L. (Adoxaceae)) inhibits the replication and viral
attachment of the human coronavirus NL63 (HCoV-NL63), which di_ers from COVID-19 but also belongs
to coronaviruses. Elderberry is the most effective means of preventing or combating coronavirus infections
at an early stage.8 One cup of elderberries contains 106 calories.9 However, their nutrient values in per 100
grams are as ~870 mg Vitamin A, 34.10 mg Vitamin C, 391.33 mg Potassium, 28.06 mg Calcium, 1.86 mg
Iron, 217 mg Sodium as well as some amount of other minerals, folic acid, amino acids, dietary fibers are
also present. This fruit is enriched with flavonoids having antioxidant and anti-inflammatory properties that
help protecting the healthy cells from the attack of harmful free radicals thus have implications in skin care,
boosting immune system which will supports the body to fight against flu, cold and other respiratory
infections.10
Allium sativum (Garlic, Lahsun)
Garlic has potent anti-oxidant properties, and helps in reducing stress and high blood pressure. It also helps
to enhance thiamine (vitamin B1) absorption in the body and prevents beriberi. The antiviral property may
be helpful in reducing the severity of colds, flu or COVID-19 infection. Hence, Garlic boosts the immune
system and helps in fighting against viruses and other diseases. It has Allicin which is board spectrum
antibiotics.11 It is reported to enhance immune health by stimulating protective white blood cells like NK
cells and macrophages.12 In an in vitro study13, Allium sativum L. (Amaryllidaceae) extract inhibited
influenza A (H1N1) virus by inhibiting the synthesis of viral nucleoproteins and polymerase activity. The
paper recommended a decoction of Allium cepa L. (Amaryllidaceae) for colds .8,14 It is always best to chop
or crush garlic before consuming it, because it works better when in contact with oxygen. Garlic is used to
add flavour to almost every form of cuisine across the world.2
Zingiber officinalis (Ginger)
Zanjabeel or Adrak is also known as Zingiber officinale Roscoe. Among other, it’s also a very important
medicinal plant which belongs to the family of Zingiberaceae. Ginger is well known for its anti-
inflammatory, antifungal, and anti-cancer properties. In traditional medicine, ginger has been extensively
used for curing colds and coughs, nausea, asthma, travel sickness, morning sickness, arthritis,
gastrointestinal complaints and even depression. Consume it as ginger tea, which involves crushing ginger
and boiling it with tea leaves and water. Powdered ginger mixed with pulverized cloves, cardamom and
caraway has been used for digestive ailments since ancient times.
Immunomodulatory (boost up the immune system of the patients which further prevent load of infection).15
Ginger is beneficial in to fight respiratory problems (relieve congestion associated with the common cold),

strength immunity (due to high level of anti-oxidant), Relieve stress (due to combination of the strong
aroma and healing property), improve blood circulation (due to presence of vitamin, minerals and amino
acids in ginger it can help restore and improve blood circulation and prevent fat from deposition in arteries
helping to prevent heart from Cardiac Vascular Disorder.16
Tinospora cordifolia (Giloy, Guduchi)
Giloy or Guduchi, scientific name Tinospora cordifolia, is a plant being used from centuries for its
medicinal values. Many studies have reported the hypolipidemic, hypoglycemic, hepatoprotective,
antibacterial, anti-inflammatory, antiosteoporotic, antiobesity, anticarcinogenic and antimutagenic
properties of giloy.17 Guduchi or Giloy herb is suggested to contain various diterpene compound and
polysaccharides including arabinogalactan polysaccharide. These polysaccharides and terpenoids are
immunomodulating and adaptogenic in nature. Various studies on Giloy herbal extract revealed that it
could cause imperative enhancement in IgG antibodies in the serum and activation of macrophages,
induction of cell regulated immunity and humoral immunity.18
Ocimum sanctum (Holy Basil, Tulsi)
Tulsi, also called as holy, basil. Many in-vitro and in-vivo reports on animals and humans have proven its
therapeutic potential as Antioxidant, anti-aging, anticancer, antiviral, antimicrobial properties,
immunomodulatory activity, immunomodulatory activity, antipyretic activity, anti-arthritic activity,
treatment of gum ulcers, kidney problems, earache, menstrual irregularities, arthritis, anorexia and malaria
and used as a haemostypticin childbirth etc.19 Interestingly, the role of tulsi for scientific evidence against
COVID-19 has also been elucidated.18
Curcuma domestica (Turmeric, Haldi)
Turmeric, scientific name Curcuma domestica is a perennial herb and belongs to the family Zingiberaceae.
The “Indian saffron” is a yellow orange spice and medicinal herb that has been used for thousands of years.
Turmeric contains a bioactive compound known as curcumin, which acts as an anti-inflammatory agent.
Commonly used in India for curries and other dishes, it can also be consumed as a decoction (kadha) made
from grated ginger, tulsi and turmeric once daily to improve immunity as recommended by AYUSH. It is
one of the most well researched spice, explored for its therapeutic properties. The main phytochemical
includes diarylheptanoids such as curcumin. Curcumin is very helpful in addressing such issues and
enhancing the immunity system. Previous finding has proven that it has therapeutic potential as antifungal,
antiviral, antioxidant, anti-inflammatory, cardiovascular and anti-diabetic effects, gastrointestinal effects,
anticancer effect, antimicrobial activity, hepatoprotective and renoprotective effects, photo-protector
activity and in the treatment of inflammatory and edematic disorders and alzheimer disease.20
Syzygium aromaticum (Clove, Laung)
Clove, scientific name Syzygium aromaticum. The consuming whole cloves can help boost the immune
systemperfectly. Clove essential oil may have Nutritional Therapeutic Potential effects due to its various
effects, which includes antimicrobial, anti-fungal, anti-viral, an-ti-inflammatory, cytotoxic, analgesic,
anesthetic activities, very potent as antioxidants, and inhibits post binding en-try of severe acute respiratory
syndrome (SARS) coronavi-rus into cells. Besides, anti-platelet activities; prevent the formation of a
thrombus or a blood clotting. Therefore, essential oil of cloves may be considered the most candi-dates to
combat the coronavirus and protecting against sudden death seen in some patients infected by Coro-navirus
(COID 19), resulting from embolism associated with hypercoagulable formation. Clove Oil should only be
diffused in well-ventilated places, and diffusing treat-ments shouldn’t exceed more than 60 minutes each
time.21

Withania somnifera (Ashwagandha)
It is a small shrub with pale green flowers, simple leaves, and red berries. More commonly known as
ashwagandha, Indian ginseng. Most of the benefits from Ashwagandha are from the root and the leaves.
The leaves are most commonly used in teas preparation. The root can be taken in many ways but it's most
commonly dried, powdered, and taken as a supplement these days. The extract of Ashwagandha can reduce
blood sugar levels, cortisol levels, symptoms of depression, and inflammation. It helps increase strength,
muscle mass, and improve brain function as well. Ashwagandha improves the body's defense against
disease by improving the cell-mediated immunity. It also possesses potent antioxidant properties that help
protect against cellular damage caused by free radicals. It also shown inhibitory properties against many
cancers, (breast, colon, prostate, colon, ovarian, lung, brain), along with their mechanism of actions and
pathways involved.22,23 Ashwagandha extracts, has shown a strong effect related to immune health and
stress reduction.24
Planax quinquefolius (Ginseng)
Ginseng is a plant in the family Araliaceae and the genus Panax with the formal name of Panax ginseng C.
A. Meyer and the treasure of traditional herbal medicine resources as the “King of Herbs.” 2526 Acute
respiratory tract infection induced by COVID-19, influenza or chronic diseases causes the horrible threat to
human health in the whole world. Based on the effect of benefiting Qi, ginseng can strengthen human
immunity against acute respiratory tract infection.27
Fenugreek is a well-known herb in the Ayurvedic system of medicine which acts a natural anti-oxidant and
strengthens immune system. It is not only used as an herb (dried or fresh leaves), spice(seeds), vegetable
(fresh leaves) but also as a condiment in artificial flavoring of maple syrup or in the production of
steroids.28
Nutraceuticals and Herbal Extracts29
Vitamins.
A daily intake of 20-50 μg of vitamin D was recently recommended for obese individuals, healthcare
workers and smokers in order to enhance their resistance to COVID-19 infection.
Dietary minerals
Selenium
The importance of selenium for optimal immune function.
Zinc
Elderly individuals are often deficient in zinc, which is essential for immune function.
Iron
The strict regulation of serum iron concentration could thus provide favorable clinical outcomes for patients
with COVID-19.
N-acetyl-cysteine (NAC)
NAC, which is derived from the naturally occurring amino acid, cysteine, is most commonly prescribed to
patients suffering from various respiratory complications.
Probiotics
Nutritional supplementation with probiotics has been reported to be beneficial for patients suffering from
respiratory tract infections.
Omega-3 fatty acids
omega-3 fatty acids have proven to be effective in reducing airway inflammation and bronchoconstriction,
have also exhibited efficacy against viral infections (102,103), their potential for use against COVID-19
warrants further investigation

β-glucans
β-glucans, which are potent activators of immune cells, β-glucans can help to reduce morbidity and
mortality associated with COVID-19.
CONCLUSION
Medicinal plants and herbs are better alternatives to treat several diseases. During the COVID-19 pandemic
in december 2019 when no proper allopathethic medicine was available to treat COVID-19, various
traditional medicinal plants and herbs have been used as medicines and resulted in positive health effects
among COVID-19 patients. In the present review, we have discussed the possible potential uses of
medicinal plants and herbs to boosting immunity against these viruses and also prevent or even treat
COVID-19 infections.
