Epilobium parviflorum Schreb. - (Onagraceae) - has been used for a long time as a medicinal plant for the treatment of various prostate symptoms, like prostate adenoma and associated disorders. Epilobii herba, willow herb, has not been officially recognized by any of European pharmacopoeias. Epilobii herba contains various pharmacologically-useful compounds, such as polyphenols, among which are the flavonoids: quercitrin, rutin, isoquercitrin, isomyricitrin and myricitrin. The total polyphenol and flavonoid contents were determined in crude willow herb drugs. A high linear correlation was observed between the total phenolic content and the reducing power of the samples. Epilobii herba showed marked activity as a radical scavenger, indicating that it has effective activities as hydrogen donors and primary antioxidants to react with lipid radicals.
