Unauthorized herbal treatments pose risks: Health Canada

Tuesday, January 9, 2007 | 02:03 PM ET

Certain unauthorized natural health products marketed to treat erectile dysfunction and for weight loss contain undeclared pharmaceutical ingredients that should only be taken under medical supervision, says Health Canada.

Sold as sexual enhancement drugs, Kang Da, along with four other unlabelled products, could lead to sudden vision loss, increased heart rate, decreased blood pressure, penile tissue damage, permanent loss of potency, urinary tract infections, indigestion, headaches and dizziness, Health Canada said in a release issued Monday.

Similarly, Qing Zhi and another unlabelled weight-loss products contain sibutramine, a prescription drug to curb appetite. Use of these unauthorized products could cause vision problems, increased heart rate and blood pressure.

The products are not authorized for sale in Canada but may have been purchased online or brought into the country by travellers.

Consumers should stop using the products immediately and consult a health professional or Health Canada at (613) 957-2991, or toll free at 1-866-225-0709.
