The protophyte of Polygonum is regarded as rhizome and root of Polygonum cuspidatum Sieb. et Zucc., perennial herbaceous, being one of the Chinese medicinal herbs most in use in ancient China. Resveratrol can lower levels of the amyloid-beta peptides that cause the plaques in the brain leading to Alzheimer's disease. Resveratrol may also be effective in fighting other human amyloid-related diseases such as Huntington's, Parkinson's and prion diseases.
