Synopsis

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

Knotgrass (Polygonum aviculare) has a long history of use in traditional medicine systems, particularly in Europe and Asia, for a variety of ailments, including infections. Historical sources suggest knotgrass was employed as a remedy for respiratory tract infections, diarrhea, and other conditions possibly linked to underlying viral causes. The use of knotgrass in folk medicine for "cooling" fevers and treating flu-like symptoms likely contributed to its reputation as a plant with antiviral potential. However, the evidence for its efficacy against viral infections is primarily anecdotal and based on traditional herbal practices rather than modern scientific studies.

Limited in vitro research has explored the antimicrobial effects of knotgrass, but studies specifically addressing antiviral activity are scarce and inconclusive. The plant contains flavonoids, tannins, and phenolic compounds, which are known to have some general antimicrobial and antioxidant properties, but direct evidence supporting effectiveness against viral infections in humans is lacking. Therefore, while knotgrass has traditionally been used to support health during infections, there is currently insufficient scientific validation for its use specifically against viral infections. Most current recommendations for its use in this context are based on traditional knowledge rather than robust clinical research.
