Best Antiviral Herbs to Boost the Immune System and Fight Infection

Herbs have been used for treating various kinds of illnesses and infections since time immemorial. Commonly found in the kitchen, herbs have excellent antiviral properties.

Due to their concentration of potent plant compounds, herbs have several antiviral and antibacterial properties and are favored by natural medicine practitioners. The development of viruses in the body can be inhibited by antiviral herbs. You can use them to treat infections because they are absolutely safe and generally cause no or few side effects.

The immune system is the body’s protection against viral pathogens. It can be bolstered by many antiviral herbs. Apart from combating viral infections, antiviral herbs also improve the immune system and function as natural flu treatments. They also have a number of cardiovascular, metabolic, and anti-inflammatory benefits.

 Doctor's Advice:

"Incorporating a variety of herbs and spices regularly into a healthy diet has a very low risk of harm and a reasonable chance of helping our immune system fight off infections," says Deborah Ann Ballard, M.D., M.P.H., Internal Medicine Doctor at Duke Integrative Medicine.


Here are 11 herbs that have potent antiviral properties.

  1. Elderberry 

    Elderberry fights diseases such as measles, herpes, and viral or bacterial infections effectively. Elderberry can be used as a natural treatment for A and B influenza, according to a report published in the Journal of Traditional and Complementary Medicine. 

    Studies have supported the protective effects of elderberries. It has been shown that these berries promote immune function by signaling molecules that control immune responses and inflammation to increase cytokine production.

    Elderberry is typically sold as a syrup or as dried berries. You can make your own syrup at home by combining dried elderberries, raw honey, and boiling water. The flower can also be used to make a natural tea. Any part of the elderberry plant, such as buds, bark, roots, or leaves, may be used for fantastic health advantages.

  2. Echinacea

    The regular use of echinacea contributes to a stronger immune system and better overall health. Echinacea phytochemicals have the potential to reduce tumors and virus infections. The active compounds in this plant prevent bacteria and viruses from entering healthy cells. Therefore, the use of echinacea greatly decreases the chances of infections of any kind.

  3. Oregano

    Oregano is an herb that belongs to the mint family and is well known for its exceptional therapeutic characteristics. It contains plant compounds like carvacrol that have antiviral properties. 

    The antiviral effects of oregano oil and carvacrol can counteract herpes simplex infection type 1 (HSV-1), rotavirus (a typical cause of diarrhea in infants and children), and respiratory syncytial virus (RSV), which triggers respiratory diseases.

  4. Sage

    Sage, another member of the mint family, is a fragrant herb that has been used to treat viral infections in ancient and Ayurvedic medicine. 

    The antiviral impacts of sage are primarily attributed to two compounds, called safficinolide and sage one. These are mainly found in the leaves and stem of the plant. 

  5. Calendula

    This antiviral herb has high levels of flavonoids, which are plant-based antioxidants that protect cells from free radical damage. Calendula also fights bacteria, inflammation, and viruses. It’s made into tinctures, ointments, and washes to cure infections, burns, and wounds, and to quickly heal cuts. Calendula ear drops are also used in infants to prevent ear infections.

  6. Garlic

    Garlic is a common natural remedy that’s used for a wide variety of disorders, including viral infections. Experiments have shown that garlic is extremely efficient in destroying several microorganisms that are responsible for both common and rare infections, including tuberculosis, pneumonia, thrush, and herpes.

    Garlic can be used to treat eye and ear infections because of its antiviral effects. Raw garlic has many other health advantages, including the ability to minimize cancer risk, control hypertension, improve cardiovascular health, and combat hair loss.

  7. Quercetin

    A naturally occurring polyphenol and flavonoid, quercetin is best known for its strong anti-inflammatory and immune-enhancing capabilities. Many foods contain this major antioxidant, such as red onion, fruit, elderberry, and green tea.

    Quercetin has long been admired for its antioxidant potential. Its phenolic properties allow it to neutralize the damage caused by free radicals via the donation of a hydrogen atom.

  8. Olive Leaf  

    The olive leaf also has antiviral properties that can help cure the common cold and harmful infections, including candida, meningitis, influenza, chronic fatigue syndrome, hepatitis B, malaria, tuberculosis, and gonorrhea. It also treats dental, ear, and urinary tract infections, and is a natural treatment for shingles.

    Olive leaf extracts effectively fight against a number of disease-causing microbes, including some influenza-causing viruses and other respiratory infections. Invading organisms are destroyed by the powerful compounds found in olive leaves, and viruses are prevented from reproducing and causing an infection. Furthermore, a study undertaken at the New York University School of Medicine found that certain HIV-1 infection-associated effects were reversed by olive leaf extracts.

  9. Ginseng

    Ginseng is present in the roots of plants in the Panax genus, which occurs in East Asian and American varieties. It has been shown to be particularly effective in combating viruses and has long been used in traditional Chinese medicine.

    Ginsenoside compounds have antiviral effects against hepatitis B, norovirus, and coxsackievirus, which are associated with several serious illnesses, including meningoencephalitis, a brain infection.

  10. Vitamin C

    One of the best immune system boosters of all is vitamin C. A lack of vitamin C can make you more vulnerable to illness. Oranges, grapefruits, tangerines, tomatoes, bell peppers, lettuce, kale, and broccoli are foods that are rich in vitamin C. Vitamin C is one of the most popular hair, skin, and nails vitamins.

    The daily consumption of vitamin C is essential for good health because it is not produced or processed by your body. The good news is that vitamin C is present in so many foods that, unless a doctor recommends it, most people don't need to take a vitamin C supplement.

  11. Vitamin B6

    To promote metabolic processes in the immune system, vitamin B6 is essential. Chicken and cold-water fish such as salmon and tuna contain vitamin B6. This vitamin is also present in chickpeas, which are the main ingredient in hummus, and green vegetables.

    B vitamins (including B12 and B6) are essential for a healthy immune response. However, many adults are deficient in them. Vitamin B12 supplements are widely available. Before you start taking supplements, consult your doctor.


    Since ancient times, herbs have been used as natural remedies.

    These include common kitchen herbs, such as basil, sage, and oregano, as well as lesser-known herbs, such as astragalus and Sambucus.

    They have powerful antiviral effects against numerous viruses that cause infections in humans.

    By incorporating them into your favorite recipes or making them into teas, it is easy to add these powerful herbs to your diet.
