Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Birch polypore (Fomitopsis betulina, formerly Piptoporus betulinus) has a long history of traditional use, particularly in European folk medicine, for supporting the body during infections, including those of viral origin. Historical texts and ethnobotanical records describe its use as a tea or tincture for general immune support and to help with various infections, although these sources do not specify viral infections in the modern sense. Its traditional use is partly justified by its content of bioactive compounds such as polysaccharides and triterpenoids, which are known in other fungi to have immune-modulating and antimicrobial properties.

Scientific studies regarding its antiviral properties are limited. Some in vitro research indicates extracts of F. betulina may exhibit activity against certain viruses, such as the influenza virus, but these findings are preliminary and mostly laboratory-based. No robust clinical trials in humans have validated its efficacy for treating or preventing viral infections. Therefore, while traditional use is well documented and there is some suggestion from laboratory studies of potential antiviral effects, the overall level of evidence remains low.

In summary, Birch polypore is used for infection and immune support based on traditional practices rather than strong scientific validation, and any antiviral effects are not well established in clinical contexts.
