Polygonum cuspidatum root extract, also known as Japanese knotweed, Mexican bamboo, and, in Traditional Chinese Medicine as Hu Zhang, is a plant whose root is a good source of the potent polyphenolic antioxidant trans-resveratrol, which is considered the most bioavailable form of resveratrol. Polygonum cuspidatum root extract is used in traditional medicine to treat various disorders through the actions of resveratrol, a type of natural phenol with antioxidant, antimicrobial, and anti-inflammatory activity.

Due to its high concentration of resveratrol, Polygonum cuspidatum root extract is treated as an excellent ingredient to anti-aging skin care products. Resveratrol forms soluble molecules with certain metal ions, thereby inactivating them so they cannot produce free radicals. This action combined with its potent antioxidant capability makes resveratrol highly effective in preventing the harmful effects of free radicals that can lead to premature skin aging.
