| On April 9, 2001, the FDA released a public advisory warning the public
that botanicals containing Aristolochia, Bragantia, or Asarum
may contain aristocholic acid. The FDA also lists specific products that
were shown to have aristolochic acid during sample testing of 34 products
listing Aristolochia spp. or an ingredient that can be inadvertently
substituted with Aristolochia spp. The warning was released in light
of information relating to the association of aristocholic acid exposure
and urethral cancer in a two patients in France, the identification of
two cases of end stage kidney failure in two individuals using botanicals
containing aristolochic acid in the United States, and the discovery of
aristolochic acid containing botanicals available in the United States.
