Aristolochic acids are a family of carcinogenic, mutagenic, and nephrotoxic compounds commonly found in the plant family Aristolochiaceae, including Aristolochia and Asarum (wild ginger), which are commonly used in Chinese herbal medicine.[1][2] Aristolochic acid I is the most abundant of the aristolochic acids and is found in almost all Aristolochia species.[3] Aristolochic acids are often accompanied by aristolactams.[4]

Aristolochic acids are slightly soluble in water, have a melting point between 281 and 286 degrees celsius,[5] and have a bitter flavor.[6]

Toxicity[edit]

Aristolochic acids are hypothesized to be causative agents in Balkan endemic nephropathy;[7][8][9] and a related—possibly identical—condition known as "Chinese herbs nephropathy".[10] Exposure to aristolochic acid is associated with a high incidence of uroepithelial tumorigenesis,[11] and is linked to urothelial cancer.[12][13]

In April 2001, the Food and Drug Administration issued a consumer health alert warning against consuming botanical products, sold as "traditional medicines" or as ingredients in dietary supplements, containing aristolochic acid.[14] The agency warned that consumption of aristolochic acid-containing products was associated with "permanent kidney damage, sometimes resulting in kidney failure that has required kidney dialysis or kidney transplantation. In addition, some patients have developed certain types of cancers, most often occurring in the urinary tract."[14]

In August 2013, two studies identified an aristolochic acid mutational signature in upper urinary tract cancer patients from Taiwan.[15][16] The carcinogenic effect is found to be the most potent found thus far, exceeding the amount of mutations in smoking-induced lung cancer and UV-exposed melanoma. Exposure to aristolochic acid may also cause certain types of liver cancer.[15]
