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. ***
GUIDANCE: *** Districts may detain without physical examination bulk
or finished dietary supplements or drugs, or bulk or
finished products of other commodity types that are
identified as being composed, in whole or in part, of any
Aristolochia spp. And those species of Asarum, Cocculus,
and Thottea listed in Attachment A. ***
*** Products identified using the traditional Chinese
Herbal Medicine names of "fang ji," "guang fang ji," "guang
mu tong," or other names noted in Attachment B, may also be
detained without physical examination. ***
Products from the firms identified in *** Attachment C ***
may also be detained without physical examination.
If product labeling includes claims for the diagnosis,
cure, mitigation, treatment, or prevention of disease, use
the new drug charge and the misbranding drug charge. 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, (301) 827-
1138, 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 Division of Field Science at (301)
827-7605.
For questions or issues concerning declared ingredient
names, please contact Sal Evola, Office of Compliance,
