Anything vaguely labeled as "detoxes" or "cleanses". Take for example the Teamie cleanse teas. They are usually full of unhealthy diuretics and laxatives to encourage weight loss. They have been linked to drug induced liver damage and aren't regulated by the FDA. The worst part is they are receiving huge endorsements from celebrities. It's pretty easy to tell by the advertisement that the claims are pseudoscience bullshit, but they marketed as health products. Call me crazy but something that can lead to high heart rate/ blood pressure, and vomiting, all just so you can shit your brains out and lose some water weight isn't really a "health" product.
