The FDA is warning that dozens of tejocote root weight-loss supplements sold online do not contain tejocote root at all. Instead, testing found the toxic plant yellow oleander, which the FDA says can cause severe or even fatal heart, nerve, and digestive reactions. This is information, not medical advice; anyone with symptoms after using one of these products should contact a clinician or poison control right away.
What did the FDA actually find?
The agency confirmed that more than 20 branded products marketed as tejocote root contained yellow oleander seed instead, according to an alert the FDA says was most recently updated on March 11, 2026. Named products include Chupa Panza, SiluetaYa Mexican Tejocote Roots, VidaSlim, Alipotec ELV, Green ELV Nutrition's Elv Control Herbal Supplement, and more than a dozen similarly labeled brands sold through Amazon, eBay, Etsy, and standalone sites like Vidaslim.com and Alipotecus.com.
How serious is the risk?
The FDA says it has received adverse event reports tied to these products, including at least one serious case linked to the Green ELV Nutrition brand. Yellow oleander contains compounds that affect the heart's electrical rhythm, and the FDA's guidance for anyone who has used one of the flagged products is direct: stop using it, dispose of it, and call 911 or a poison control center if symptoms appear.
Why does this keep happening in the supplement business?
Weight-loss supplements don't require FDA approval before they reach store shelves or marketplaces. Per the NIH Office of Dietary Supplements, manufacturers themselves are responsible for their products' safety and for accurate labeling, and the agency notes that some labels have historically failed to disclose everything a product actually contains. Enforcement tends to happen after products are already on the market and problems surface. The FTC, which polices supplement advertising claims alongside the FDA, says it has filed more than 120 cases over the past decade challenging unsubstantiated health claims for supplements, an indication of how often marketing outpaces what a product can actually deliver or, in cases like this one, what it actually is.
What should shoppers do now?
Anyone who bought a tejocote root product from the brands or retailers named in the FDA alert should stop using it immediately and check the product name and seller against the agency's list before assuming it's safe. Because these products were sold through open online marketplaces rather than a single storefront, a listing can reappear under a slightly different name even after it's flagged.
The bottom line
The FDA says more than 20 tejocote root weight-loss products actually contained the toxic plant yellow oleander, not the advertised ingredient, with reports of serious adverse effects. If you have one of the named products, stop using it and dispose of it, and contact a clinician or poison control if you've taken it and feel unwell.
