American Botanical Council Clarifies Safety Issue on Star Anise Tea
On September 10, the U.S. 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 (Illicium
anisatum L., Illiciaceae) for the safe Chinese star anise (I. verum
Hook. f.).
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 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, 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 FDA, as acknowledged in FDA’s advisory.
Because the two species’ star-shaped seedpods look so
much alike, the herbal tea industry many years ago developed laboratory techniques
to distinguish between them. In-house quality control laboratories at herb tea
companies in the United States 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. "The herb industry has known about the
problem with the two kinds of star anise for many years and has 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 L., Apiaceae),
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 United States.
