• Balance a fragile yin.
• Treat weak bones and premature graying of hair
• Protection of skin against UVB damage^[1]

When taken internally, P. multiflorum also has a laxative effect.

P. multiflorum contains stilbene glycosides similar to resveratrol and with superior antioxidant activity.^[2]

Resveratrol is extracted from P. multiflorum's close relative, Japanese knotweed (P.Cuspidatum). Resveratrol has been suggested to extend lifespan by a variety of mechanisms.
