This “all-natural blend of Chinese herbs” will get this year’s award for the most fraudulently labeled supplement.

FDA warns consumers and healthcare professionals that Que She, marketed as an herbal weight loss supplement, contains unlisted and active pharmaceutical ingredients that could harm consumers, especially those with cardiovascular conditions.

Que She is advertised online and in retail outlets as a “Slimming Factor Capsule” and as “an all-natural blend of Chinese herbs.” But the FDA analysis of Que She found that it contains:

  • Fenfluramine (Pondimin)
    • A stimulant drug
    • It was withdrawn from the US market in 1997 after studies demonstrated that it caused serious heart valve damage.
  • Propranolol (Inderal)
    • A prescription beta-blocker drug
    • Propranolol may pose a risk to people with bronchial asthma and certain heart conditions.
  • Sibutramine (Meridia)
    • A controlled substance and prescription weight loss drug
    • A recent study showed an association between sibutramine use and increased risk of heart attack and stroke in patients with a history of heart disease.
  • Ephedrine
    • A stimulant drug
    • Ephedrine is legally marketed over-the-counter for temporary relief of asthma.
    • It may pose a risk to people with certain cardiovascular conditions.

The bottom line?

People who purchased Que She should stop taking it immediately and consult a healthcare professional.

Healthcare professionals and patients are encouraged to report adverse events or side effects related to the use of this product to the FDA’s MedWatch Safety Information and Adverse Event Reporting Program.
