Warning about ingesting teas and health products containing Star Anise, Health Canada

As a precautionary measure, Health Canada is advising Canadian consumers not to ingest herbal teas or health products containing the herb "star anise" unless they are confident that it is Chinese star anise (Illicium verum Hook. f).

Consumers should verify that their product contains Chinese star anise. Otherwise, consumers should avoid using the following products:

-- blended herbal teas containing the herb "star anise"

-- bulk star anise for the purpose of brewing teas

-- therapeutic and natural health products (such as medicinal herbal teas or homeopathic medicines) containing star anise

There have been reports in the U.S. and Europe of adverse reactions associated with consumption of blended teas containing "star anise" and with the consumption of teas brewed solely from "star anise." In some of the cases, herbal tea was being used as a treatment for infant colic. Adverse reactions ranged from mild nausea to convulsions and seizures, and in all cases, symptoms were temporary. To date, there have been no reports of adverse reactions in Canada associated with products containing star anise, nor evidence that any foods or health products sold in Canada, contain toxic varieties of star anise.

Consumers who ingest one of the potentially toxic varieties of star anise may suffer an adverse reaction and should consult a physician if this occurs.

There is more than one type of star anise. Chinese star anise does not represent a health and safety concern and has a long history of safe use in foods. The dried seed pods of Chinese star anise can be found in certain spice mixtures and cooking pastes used in foods, in some herbal tea blends, and in certain therapeutic and natural health products. Other species of star anise, such as Japanese star anise, are used for decorative and aromatic purposes but are not considered safe for human consumption and can be toxic if enough is ingested.

It is important to note that this advisory does not apply to an unrelated herb commonly known as 'anise' (Pimpinella anisum). Anise does not represent a health and safety concern in foods and has a long history of safe use.

With respect to health products containing star anise, Health Canada is requesting evidence from the manufacturers of these products to show that the star anise ingredient is the correct variety (Chinese star anise) and that it does not pose a risk to health. Health Canada will keep Canadians informed of any developments related to this issue.

For natural health products, consumers and health care professionals may report any adverse reactions by contacting Health Canada toll-free by telephone (866) 234-2345 or fax (866) 678-6789.

For foods, any adverse reactions suspected as being associated with star anise may be reported to the Canadian Food Inspection Agency's Food Safety Concern Line. Call the Canadian Food Inspection Agency's general toll-free number 1-800-442-2342 to obtain the Concern Line number for your province.

Consumers who identify that they have the toxic species of star anise should return the product to the point of purchase. Retailers should contact the Health Products and Food Branch Inspectorate at 1-800-267-9675 if they have any questions about disposal of the product.

Is too much soy bad for men?

While soy may be beneficial to women in a variety of ways, research in monkeys suggests that it could have an adverse effect on the behavior of men, according to researchers from Wake Forest University Baptist Medical Center. Reporting in the current issue of the scientific journal Hormones and Behavior, the researchers found that in male monkeys, "long-term consumption of a diet rich in soy isoflavones can have marked influences on patterns of aggression and social behavior." Isoflavones are a naturally occurring plant estrogen in soy protein. "Although considerable attention has been directed at the potentially beneficial effects of isoflavones in reducing the risk of various cancers, osteoporosis, cardiovascular disease and postmenopausal symptoms, less effort has been invested in characterizing neurobehavioral effects," according to the study.

Research news from the Friedman School of Nutrition Science and Policy at Tufts University

Vitamin E to Prevent the Common Cold? Each year, millions of people are mildly bothered by the common cold, but among elderly individuals the common cold can be much more debilitating. A groundbreaking study by Simin Nikbin Meydani, DVM, PhD, of the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University, and colleagues, published in the Journal of the American Medical Association (JAMA), found that vitamin E may protect against the common cold among elderly individuals residing in nursing homes. "Our study found that those taking the vitamin E supplement pills were 20 percent less likely to suffer from respiratory infections and that vitamin E supplementation reduced the incidence of common colds by about 22 percent," said Meydani, professor at the Friedman School of Nutrition Science and Policy. "Older individuals are at greater risk for respiratory tract infections, including the common cold," she continued. "Colds occur more frequ...
