What is Knotgrass?
Knotgrass (Polygonum aviculare) is a botanical extract derived from a common herbaceous plant. It is primarily used in dietary supplements formulated for urinary and kidney health. The extract contains various phytochemicals, including flavonoids and phenolic compounds, which contribute to its inclusion in herbal blends. Knotgrass is typically found in products marketed for urinary tract support and kidney function, often combined with other plant extracts to target these areas. Its use is favored in formulations aiming to provide botanical diversity and traditional herbal components.
