* urinary tract infections in women : In one study, both the large-flowered willow herb (Epilobium angustifolium) and small-flowered willow herb E. parviflorum were found to reduce inflammatory prostaglandins in the carrageenin-induced rat paw edema test; in this study, E. angustifolia was found to be 5 times more powerful than E. parviflori. Antimicrobial screening of 13 phenolic substances and 29 extracts prepared from Finnish plant materials against selected microbes found that small flower willow herb (Epilobium angustifolium L.) was one of the most active plant extracts tested against bacteria.
