The Food and Drug Administration expanded its urgent warning about weight loss supplements containing a deadly toxin masquerading as natural ingredients, threatening consumers with heart problems, neurological damage, and potential death.

Toxic Plant Substituted for Labeled Ingredients

Federal investigators determined that products marketed as containing tejocote root or Brazil seed actually contain yellow oleander, a poisonous plant native to Mexico and Central America. The FDA investigation, ongoing since 2023, has identified over two dozen contaminated products sold through major retailers, including Amazon and eBay. Yellow oleander causes severe abdominal pain, vomiting, diarrhea, cardiac abnormalities, and death. The agency warns consumers who purchased these supplements to seek immediate medical attention, even if consumption occurred weeks or months ago.

The latest product added to the FDA’s warning list is Chupa Panza, sold by Naturista Reyes through multiple business entities including Suerte Y Salud LLC and La Tia Mana LLC. eBay removed the listing last week following FDA notification. However, the agency noted that not all retailers cooperated with voluntary recalls, leaving potentially dangerous products available through various online platforms and natural health websites. The FDA classifies yellow oleander as a toxic substance of serious concern to public health officials.

False Marketing Promises Target Weight Loss Seekers

These contaminated supplements promised weight loss, appetite suppression, fat burning, and detoxification benefits with little scientific evidence supporting such claims. Tejocote root, legitimately derived from a hawthorn tree native to mountainous regions of Mexico and Guatemala, has traditional uses in Mexican medicine for respiratory and digestive health. The fraudulent products exploit consumer trust in natural remedies while substituting deadly ingredients.

Emergency Action Required for Consumers

The FDA urges anyone experiencing serious side effects from these products to call 911 or seek emergency medical help immediately. Symptoms requiring urgent attention include severe abdominal pain, persistent vomiting or diarrhea, irregular heartbeat, or cardiac abnormalities. The agency recommends contacting healthcare providers even without current symptoms if these supplements were consumed previously. The ongoing investigation highlights risks associated with unregulated dietary supplements and the importance of purchasing health products only from verified, reputable sources with proper quality control measures and accurate ingredient labeling.
