"Detention Without Physical Examination of Bulk/Finished Dietary Supplements Products Containing Aristolochic Acid"

Reason for Alert

The botanical Aristolochia spp. and other plants in the Aristolochiaceae family are widely used as ingredients in traditional Chinese herbal medicines and other traditional medicines. These products may often be labeled for drug use (e.g., claims that they are intended for use in the diagnosis, cure, mitigation, treatment, or prevention of diseases), although there are no approved new drug applications (NDAs). Some products containing botanicals in this family may also be labeled as dietary supplements or may not be labeled in accordance with the requirements for any specific FDA-regulated product. Plants in the Aristolochiaceae family contain aristolochic acid, which is a substance known to result in serious adverse health effects when taken orally by humans or animals. Several outbreaks of renal failure in recent years have been attributed to the use of Chinese herbal medicines that were later shown to contain aristolochic acid. In each instance, the source of aristolochic acid was determined to be an aristolochia spp. plant that was used in the product for one of two reasons: (1) the plant ingredient that was listed on the label was mis-identified; or (2) the identity of the plant ingredient or product was confused with an aristolchia-containing ingredient or product because the traditional Chinese names were misinterpreted or similar. *** Aristolochic acid is a potent carcinogen and nephrotoxin. Its nephrotoxic potential has been demonstrated in animals and humans in case reports and in at least one human clinical study. *** Products that contain a large amount of aristolochic acid have been documented to result in the rapid onset of acute toxicity symptoms. However, a product containing a small amount of aristolochic acid could be used for years with no apparent adverse effects until serious, irreversible effects, such as renal damage, has occurred. In sum, products containing aristolochic acid cause renal damage and can cause or contribute to renal failure. There are analytical methods available to examine suspect raw material and finished product for the presence of aristolochic acid. *** products that contain Aristolochia spp. or other botanicals that contain aristolochic acid should be evaluated in order to establish that the product is free of aristolochic acid. ***Note: Charge statement revised on 04/23/2019.

If the product labeling does not include disease claims but the district has determined through other means (e.g.,conversation with the importer, letter from the importer, etc.) that the product is intended for disease use, then use the drug misbranding charge. In this instance please contact the Deputy Chief Counsel For Litigation, to further discuss the circumstances and evidence of the importation and whether or not a new drug charge would also be appropriate. In addition, the appropriate food charges (see below) should be included. If the product does not appear to be a drug, only food adulteration charges should be used. If the products appear to be finished products labeled as dietary supplements, charges under section 402(a)(1), section 402(f)(1)(A), and section 402(f)(1)(D) should be used. If the product is a bulk dietary ingredient (e.g., root, powder, extract) charges under section 402(a)(1) and section 402(f)(1)(A) should be used. A product labeled as a dietary supplement may be released when a firm is able to provide analytical evidence that it is free of aristolochic acid. Only certificates of analysis or other evidentiary documents that rely on liquid chromatography-mass spectrometry analytical determination of aristolochic acid content should be accepted as a basis to release detained product. For questions or issues concerning science, science policy, sample collection, analysis, preparation, or analytical methodology, contact the Office of Regulatory Science at 301 796-6600. All requests for removal from detention without physical examination should be address to DIOP 301-796-0356.
