The takeaway

The FDA has expanded its warning about tejocote-root weight-loss supplements contaminated with yellow oleander, a poisonous plant that can cause severe or fatal heart, neurological, and digestive symptoms. Three products — Easy Forte Natural Fiber and two Niwali Tejocote items — were added September 17, bringing the warning list past a dozen products. The agency urges consumers to stop use and call a doctor or 911 for symptoms.

The FDA has widened its warning about tejocote-root weight-loss supplements that testing found contaminated with yellow oleander, a poisonous plant that can trigger severe or fatal heart, neurological, and digestive problems.

What's new

On September 17, the agency added three more products to its warning list: Easy Forte Natural Fiber, sold through Amazon by Comercializadora Naturista del Bajio, and Niwali Tejocote Pieces and Niwali Tejocote Capsules, sold by Global Mix Inc. through eBay and Everymarket.com. They join more than a dozen other tejocote-root products the FDA has flagged this year, including Slim Elixir, D Magic Plus, B. Magi, Chupa Panza, SiluetaYa Mexican Tejocote Roots, VidaSlim, and ALIPOTEC ELV Mexican Tejocote Root.

Why it's dangerous

Tejocote root itself is a traditional Mexican fruit used in some folk remedies, but FDA testing found that some products marketed as tejocote actually contain yellow oleander (Cascabela thevetia), a toxic plant that closely resembles it. The FDA says yellow oleander can cause neurological, gastrointestinal, and cardiovascular effects "that may be severe, or even fatal," including nausea, vomiting, dizziness, diarrhea, abdominal pain, and dangerous changes in heart rhythm.

What the FDA wants consumers to do

  • Stop using any tejocote-root weight-loss product and dispose of it.
  • Contact a healthcare provider if you've taken one, even without symptoms.
  • Call 911 or go to an emergency room right away for serious symptoms such as an irregular heartbeat, severe vomiting, or dizziness.
  • Contact a poison control center for additional guidance.

Refunds

Consumers who bought recalled Niwali products can seek a refund where the company has made one available; other listed products may not currently offer a refund process.

Because many of these products are sold through third-party marketplace listings rather than one central retailer, the FDA has cautioned that its warning list may not capture every product containing the toxin, and testing of additional supplements is continuing.
