Hairy Fig (Ficus hirta) has a long history of use in traditional medicine systems, particularly in Chinese and Southeast Asian herbal practices. Traditionally, parts of the plant, such as the root and fruit, have been used to treat various ailments, including infections and inflammatory conditions. In the context of viral infections, Hairy Fig is often included in herbal formulas believed to "clear heat" and "detoxify" the body, which are traditional concepts loosely associated with fighting infections. However, there is limited direct scientific evidence supporting the antiviral properties of Hairy Fig. Some laboratory studies have identified that extracts from related Ficus species may have weak antiviral or immunomodulatory activity, but robust, peer-reviewed research specifically on Ficus hirta and its efficacy against viral infections in humans is lacking. Most of the support for its use in treating viral infections comes from its persistent use in traditional medicine rather than from clinical trials or pharmacological studies. In summary, the use of Hairy Fig for viral infections is justified primarily by traditional knowledge, with little scientific validation available at present. Its evidence rating remains low due to the lack of rigorous clinical studies, but its historical use in traditional medicine is well documented.
