11 Antiviral Herbs to Boost Your Immune System and Fight Viruses
Whether it’s the common cold, flu, Ebola virus, or coronavirus, the question remains the same: how can I boost my immune system? Our body’s natural defense mechanism works tirelessly to protect us from pathogens, but sometimes it needs a little extra support. One of the best ways to bolster your immune system is by using herbs. These natural antiviral powerhouses not only add an extra layer of protection but also make your meals flavorful. Ready to dive in? Let’s explore 11 antiviral herbs to boost your immune system and fight viruses.
1. Echinacea
Echinacea, a native North American coneflower, is generally classified as an herb. Many of its chemical constituents are effective immune system stimulators, providing significant therapeutic value. According to a meta-analysis published in The Lancet Infectious Diseases, echinacea reduces the chances of catching a common cold by 58%—pretty incredible, right? It also shortens the duration of a cold by almost 1.4 days. Echinacea works by stimulating the immune response and blocking viral proteins. While generally safe, it’s essential to consult your physician before taking it, especially if you are pregnant, breastfeeding, or have a serious medical condition.

Elderberries are rich in minerals and vitamins like potassium, vitamin A, B6, and C. One cup of elderberry provides 52 milligrams of vitamin C, explaining its immune-boosting prowess. When taken at the onset of illness, elderberry helps reduce the duration and severity of symptoms. Studies show that elderberry increases inflammatory cytokine production, crucial for regulating the body’s infection response. However, some parts of the elderberry plant can be toxic, so it’s vital to prepare and harvest it correctly.
3. Andrographis
Andrographis is a potent herb known for its antiviral, anti-inflammatory, antioxidant, and anti-cancer properties. A study published in the Asian Pacific Journal of Tropical Disease (APJTD) indicates that compounds in this herb stimulate the immune response and prevent viruses from binding to cells. Andrographalide, an active ingredient in andrographis, is known to cure malaria and the influenza virus. It is commercially available in capsules or tincture forms and is generally considered safe. If you experience stomach upset, try reducing the dose and avoid taking it on an empty stomach.
4. Garlic
Garlic, a well-known kitchen ingredient, is packed with health benefits, including immune function enhancement. It helps the immune system fight germs due to a compound called allicin. Allicin boosts the response of white blood cells when they encounter viruses. Studies have shown that adding garlic to your diet can reduce the risk of viral infections and lessen the severity of illnesses if you do get sick.
5. Astragalus Root
Astragalus is a potent herb for supporting immune health. It functions as an immune stimulant and modulator. A study published in the Journal of Animal Science and Biotechnology indicates that astragalus reduces viral replication and promotes early immune response. It also benefits the immune system by affecting the gut microbiome, where 70% of our immune system resides. You can consume it by making tea, adding it to soups, or taking it in capsule form.

6. Turkey Tail
Coriolus, often referred to as turkey tail due to its color and striped pattern, has been used for centuries for its antiviral, antimicrobial, and anti-tumor properties. It contains protein-bound polysaccharides (PSP and PSK) that stimulate the immune system, reduce inflammation, and prevent diseases. It also positively affects the gut microbiome, increasing the population of good bacteria. Studies have found that beneficial gut bacteria are linked to enhanced immunity and lower cancer risk. Add turkey tail to your soups, sauces, broths, or stews for a tasty medicinal boost.
7. Reishi
Known as the “mushroom of immortality,” reishi supports immune function with its 35% beta-glucan content, a soluble fiber that enhances immune response. It improves immunity by interacting with gut microbiota and enhancing cell functionality. According to a study published in the Journal of Ethnopharmacology, reishi boosts immunity by stimulating cytokine production. It is commonly available in dried or powder form and used in tea, rice, or porridge. While you can find reishi extracts in capsule form, consuming whole food is always better.
8. Olive Leaf
We all know how great olives are, but their leaves also offer numerous benefits. Oleuropein, an antioxidant in olive leaves, has antiviral, antibacterial, and anti-inflammatory properties. Studies indicate that olive leaf extracts enhance immunity by stimulating cytokine production, increasing lymphocyte cells. Olive leaf extracts are available in capsules, soft gels, and tinctures. You can also make tea from fresh olive leaves, an excellent replacement for high-caffeine drinks.
9. Licorice Root
Licorice root is a powerhouse of selenium, zinc, magnesium, potassium, iron, and various phytonutrients that boost your immune system naturally. A study published in the Journal BMC Complementary and Alternative Medicine shows that licorice polysaccharides improve health conditions by stimulating cytokine and lymphocyte production. It also has anti-tumor properties. You can consume licorice by preparing tea, using its powder in food, or taking it as a supplement. It’s also great for digestive issues or respiratory problems. Although licorice is generally safe, it’s better to discuss it with your physician before taking it as a supplement.
10. Oregano
Oregano, a flowering plant from the mint family, is commonly used to flavor food but offers much more. A study published in the Brazilian Journal of Microbiology shows that carvacrol, the main active ingredient in oregano oil, can inhibit various human viruses. If you are allergic to mint or lavender, avoid oregano, as you may also be allergic to it.
11. Sage
Sage is commonly used for its distinct taste and aroma, but it also has antimicrobial properties that help ward off infections and support the immune system. Rosmarinic acid, a phenolic compound in sage, maintains immune system balance and is particularly beneficial for autoimmune diseases. A study published in the Journal Pharmacognosy Research indicates that sage enhances pathogen recognition and antioxidant defense. Available in fresh, dried, or tea form, sage can be added to your diet as a garnish for soups or broths.
