For Immediate Release
Austin,
TX (September 12, 2003)
On
September 10, the Food and Drug Administration (FDA) issued a Consumer Advisory
regarding the agency’s concerns about some cases of poisoning related to the
substitution of the toxic Japanese star anise for the safe Chinese star anise.
The
following day many news outlets reported the story. Unfortunately, many
consumers, reporters, and even natural foods and grocery industry members have
become confused over FDA’s actions and the ensuing publicity, incorrectly suspecting
problems with all commercially manufactured herbal teas containing star anise.
Chinese
star anise (scientific name Illicium
verum) is a safe and flavorful component of some popular herbal tea blends,
and it is also a
flavor component of spice mixes used in food products. It has the same
star-shape as Japanese star anise (Illicium
anisatum), but the Japanese species contains some toxic compounds. The
herbal tea industry has long used the safe Chinese star anise, not the Japanese
material. Chinese star anise is recognized as safe for food use by the FDA, as
acknowledged in FDA’s advisory.
Because
the two plants’ star-shaped seedpods look so much alike, the herbal tea
industry many years ago developed laboratory techniques to be able to
distinguish the safe Chinese star anise from the unsafe Japanese star anise.
In-house quality control laboratories at herb tea companies in the U.S. employ
microscopic analytical techniques as well as chemical tests to ensure that the
herbal material they receive is the proper, safe herb before it is processed
into herbal teas released to the commercial market. Several authoritative
reference books and European pharmacopeias have published analytical methods to
help make the proper distinctions.
“Herbal
teas sold by reputable companies in the United States are quite safe,” said
Mark Blumenthal, founder and Executive Director of the American Botanical
Council (ABC). “People in the herb industry have known about the problem with
the two kinds of star anise for many years and have developed quality assurance
programs to ensure that commercial herb teas use the safe Chinese star anise.”
The
cases of poisoning with Japanese star anise that the FDA cited were not related
to herbal teas produced by reputable tea companies, Blumenthal added. Most of
the poisoning cases probably involved cases where consumers purchased the toxic
Japanese star anise in bulk and made their own teas. Japanese star anise has
been sold for many years for its use as an ingredient in potpourris because of
its shape and fragrance. It is not intended for internal use.
ABC
also pointed out that the public should not confuse star anise with anise,
sometimes called aniseseed (Pimpinella
anisum), a member of the carrot family. Anise is a safe, commonly used food
flavoring that is also generally recognized as safe by the FDA. Because of its
licorice-like taste, anise oil is the main ingredient used in making “licorice”
candies in the U.S.
