Oregano is a popular herb in the mint family that’s known for its impressive medicinal qualities. Its plant compounds, which include carvacrol, offer antiviral properties.
In a test-tube study, both oregano oil and isolated carvacrol reduced the activity of murine norovirus (MNV) within 15 minutes of exposure (1Trusted Source).
MNV is highly contagious and the primary cause of stomach flu in humans. It is very similar to human norovirus and used in scientific studies because human norovirus is notoriously difficult to grow in laboratory settings (2Trusted Source).
Oregano oil and carvacrol have also been shown to exhibit antiviral activity against herpes simplex virus type-1 (HSV-1); rotavirus, a common cause of diarrhea in infants and children; and respiratory syncytial virus (RSV), which causes respiratory infections (3Trusted Source, 4Trusted Source, 5Trusted Source).
Also a member of the mint family, sage is an aromatic herb that has long been used in traditional medicine to treat viral infections (6Trusted Source).
Test-tube research indicates that this herb may fight human immunodeficiency virus type 1 (HIV-1), which can lead to AIDS. In one study, sage extract significantly inhibited HIV activity by preventing the virus from entering target cells (8Trusted Source).
Many types of basil, including the sweet and holy varieties, may fight certain viral infections.
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 (12Trusted Source).
Fennel is a licorice-flavored plant that may fight certain viruses.
A test-tube study showed that fennel extract exhibited strong antiviral effects against herpes viruses and parainfluenza type-3 (PI-3), which causes respiratory infections in cattle (13Trusted Source).
What’s more, trans-anethole, the main component of fennel essential oil, has demonstrated powerful antiviral effects against herpes viruses (14Trusted Source).

Garlic is a popular natural remedy for a wide array of conditions, including viral infections.
In a study in 23 adults with warts caused by human papillomavirus (HPV), applying garlic extract to affected areas twice daily eliminated the warts in all of them after 1–2 weeks (16, 17Trusted Source).
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).
Animal and test-tube studies indicate that garlic enhances immune system response by stimulating protective immune cells, which may safeguard against viral infections (19Trusted Source).
garlic extract have great potential as antibacterial agent against the nine multidrug resistance bacteria strains examined. Therefore, Togolese garlic may be a promising alternative that could replace antibiotics used in the treatment of urinary tract infections, especially in pregnant women whose use conventional antibiotics that will have repercussions on the health of mother and child. There is a continuous need for the development of new strategies for treatment of UTIs and further investigations are necessary to appreciate in vivo effect of garlic for develop garlic medical use, and promote them. https://www.preprints.org/manuscript/201809.0077/v1

Peppermint is known to have powerful antiviral qualities and commonly added to teas, extracts, and tinctures meant to naturally treat viral infections.
In a test-tube study, peppermint-leaf extract exhibited potent antiviral activity against respiratory syncytial virus (RSV) and significantly decreased levels of inflammatory compounds (25Trusted Source).
Rosemary is frequently used in cooking but likewise has therapeutic applications due to its numerous plant compounds, including oleanolic acid (26Trusted Source).
Rosmarinus officinalis L. (rosemary) is a medicinal plant native to the Mediterranean region and cultivated around the world. Besides the therapeutic purpose, it is commonly used as a condiment and food preservative. R. officinalis L. is constituted by bioactive molecules, the phytocompounds, responsible for implement several pharmacological activities, such as anti-inflammatory, antioxidant, antimicrobial, antiproliferative, antitumor and protective, inhibitory and attenuating activities.

Echinacea is one of the most popularly used ingredients in herbal medicine due to its impressive health-promoting properties. Many parts of the plant, including its flowers, leaves, and roots, are used for natural remedies.
Several test-tube studies suggest that certain varieties of echinacea, including E. pallida, E. angustifolia, and E. purpurea, are particularly effective at fighting viral infections like herpes and influenza (31Trusted Source).
Notably, E. purpurea is thought to have immune-boosting effects as well, making it particularly useful for treating viral infections (30Trusted Source).
Sambucus is a family of plants also called elder. Elderberries are made into a variety of products, such as elixirs and pills, that are used to naturally treat viral infections like the flu and common cold. A study in mice determined that concentrated elderberry juice suppressed influenza virus replication and stimulated immune system response (32Trusted Source).
What’s more, in a review of 4 studies in 180 people, elderberry supplements were found to substantially reduce upper respiratory symptoms caused by viral infections (33Trusted Source).
Licorice has been used in traditional Chinese medicine and other natural practices for centuries.
