Health Canada recently updated its report of adverse reactions to some of the more common herbal products, including Echinacea, ginko and St. John’s Wort. According to the report, some people have reported experiencing rashes after taking St. John’s Wort. St. John’s Wort is an herbal treatment for major depression and is available over the counter in the U.S.

Ginseng is another common herb readily available in the U.S. Ginseng is a stimulant taken orally to treat type II diabetes and sexual dysfunction in men. Ginseng also can be found in some popular energy drinks and foods. Studies show that ginseng has been linked to at least one occurrence of Stevens Johnson Syndrome (SJS), a severe adverse reaction to medication.

SJS usually begins with a fever and sore throat and progresses to rashes that cover the skin and mucous membranes. As the condition progresses, the rashes can blister over and cause the skin to fall off in sheets. The mouth and eyes also can blister, which can lead to dehydration, infection and serious eye problems and even blindness.

The International Journal of Pediatric Dentistry also reports that a 10-year-old Indian boy developed severe mouth and eye ulcers and was subsequently diagnosed with SJS after taking an “herbal medication of plant origin” prescribed by a traditional healer for treatment of a fever. According to the book, traditional therapy with herbal preparation (Ayurvedic medicine) is not uncommon in India.

Doctors advise those who experience symptoms of SJS to go immediately to the emergency room.
