The Food and Drug Administration (FDA) has issued an urgent warning about weight loss supplements that contain a toxin that can trigger neurologic, gastrointestinal and cardiovascular problems and even death. The agency identified over two dozen products featuring yellow oleander, which is a poisonous plant native to Mexico and Central America. These products are sold on platforms like Amazon, Ebay, and "natural" websites. The FDA noted that some retailers have agreed to recall the toxic products. The latest addition to the FDA's list is Chupa Panza, sold by Naturista Reyes.
