The herbal weight loss supplement Que She, advertised as “Slimming Factor Capsule” and as “an all-natural blend of Chinese herbs,” widely distributed on Internet sites such as the Bouncing Bear Botanicals website and at retail outlets such as Sacred Journey in Lawrence, Kansas, has been found to contain ingredients that can cause serious harm to consumers, according to an analysis conducted by the Food and Drug Administration (FDA).
The active pharmaceutical ingredients include fenfluramine, a stimulant drug withdrawn from the U.S. market in 1997 after studies demonstrated that it caused serious heart valve damage; propranolol, a prescription beta blocker drug that can pose a risk to people with bronchial asthma and certain heart conditions; sibutramine, a controlled substance and prescription weight loss drug that was the subject of a recent study whose preliminary findings showed an association between sibutramine use and increased risk of heart attack and stroke in patients who have a history of heart disease; and ephedrine, a stimulant drug that is legally marketed over-the-counter for temporary relief of asthma but can pose a risk to people with certain cardiovascular conditions.
In recent years, the FDA has recalled dozens of dietary supplements for weight loss because they contain undeclared ingredients that could be harmful to consumers.
Consumers who have purchased Que She should stop taking the product immediately and consult a health care professional. Any adverse events with this or any other drug should be reported to the FDA MedWatch Adverse Event Reporting Program at www.FDA.gov/MedWatch.
