41 results about "Aristolochic acid" patented technology

Aristolochic acids (English: /əˌrɪstəˈloʊkɪk/) are a family of carcinogenic, mutagenic, and nephrotoxic phytochemicals commonly found in the flowering plant family Aristolochiaceae (birthworts). Aristolochic acid (AA) I is the most abundant one. The family Aristolochiaceae includes the genera Aristolochia and Asarum (wild ginger), which are commonly used in Chinese herbal medicine. Although these compounds are widely associated with kidney problems, liver and urothelial cancers, the use of AA-containing plants for medicinal purposes has a long history. The FDA has issued warnings regarding consumption of AA-containing supplements.
