Some research suggests that ginger is effective in avian influenza, RSV, and feline calicivirus (FCV). Ginger contains phenolic compounds such as gingerols and zingerone that helps to prevent the growth of the virus. 

A study found that fresh ginger stimulated mucosal cells to release a type of cytokine that contributes to counteracting a viral infection. Another clinical trial that involved 60 volunteers with confirmed hepatitis indicated that ginger extract may decrease the activity of hepatitis C viruses. 

It is recommended to use fresh or powdered organic ginger and add it to hot drinks as a tea or other recipes. Of course you can also get more concentrated doses of ginger in supplement form.

For example, one test-tube study found that sweet basil extracts, including compounds like apigenin and ursolic acid, exhibited potent effects against herpes viruses, hepatitis B, and enterovirus (11Trusted Source).

Holy basil, also known as tulsi, has been shown to increase immunity, which may help fight viral infections.

In a 4-week study in 24 healthy adults, supplementing with 300 mg of holy basil extract significantly increased levels of helper T cells and natural killer cells, both of which are immune cells that help protect and defend your body from viral infections


Garlic has been prized for its medicinal properties for thousands of years. The compounds allicin and alliion are responsible for this common plant’s reputation as a triple threat. Garlic is anti-viral, anti-bacterial and anti-fungal and it is especially effective against viruses if chewed raw.

Additionally, older test-tube studies note that garlic may have antiviral activity against influenza A and B, HIV, HSV-1, viral pneumonia, and rhinovirus, which causes the common cold. However, current research is lacking (18Trusted Source).
