FDA Yellow Oleander Supplement Warning: Products to Avoid and What to Do

• The FDA added three products to its yellow oleander safety alert on September 17, 2026: Niwali Tejocote Pieces, Niwali Tejocote Capsules, and Easy Forte Natural Fiber.
• Stop using any product listed in the FDA alert, dispose of it safely, and contact a health care provider if you have taken it—even if the exposure happened some time ago.
• Serious symptoms require emergency help. U.S. consumers can contact Poison Control, while Canadian consumers should contact local poison services and report suspected supplement reactions to Health Canada.

What the FDA warning says

The U.S. Food and Drug Administration updated its safety alert on September 17, 2026, after testing found toxic yellow oleander in three more dietary supplements. The products were sold as Niwali Tejocote Pieces, Niwali Tejocote Capsules, and Easy Forte Natural Fiber.

Yellow oleander is a poisonous plant. The FDA says it can cause neurologic, gastrointestinal, and cardiovascular effects that may be severe or fatal. The agency has found the ingredient in products labeled as tejocote root, Brazil seed, or related botanical weight-loss products, and its investigation is still ongoing.

This is not a routine quality issue or a warning about ordinary tejocote foods. FDA testing found that certain products contained yellow oleander instead of, or in addition to, the ingredients shown on the label.

Products added on September 17, 2026

These are additions to a larger FDA alert. The agency’s list also includes other products marketed as tejocote root, Mexican tejocote, Brazil seed, or similar weight-loss supplements. Because the FDA continues to test products, the list may change.

Do not rely only on the brand name or the marketplace listing. Compare the product, packaging, seller, and product photos with the FDA’s current alert before deciding whether a supplement is affected.

What consumers should do now

1. Stop using the product. Do not take another serving, even if you feel well or the product was purchased months ago.
2. Keep the package if it is safe to do so. The label, lot information, seller details, and remaining product may help a health professional or agency identify what was taken. Do not handle loose plant material unnecessarily.
3. Contact a health care provider if you took an affected product. The FDA specifically advises people to seek medical advice even when the product was not used recently.
4. Get emergency help for serious symptoms. Call 911 in the United States or 911 in Canada if someone collapses, has trouble breathing, has a seizure, cannot be awakened, or develops severe or rapidly worsening symptoms.
5. Report the product or suspected reaction. Reporting can help regulators identify additional products that may contain undeclared yellow oleander.

Do not try to make yourself vomit or treat a possible poisoning with home remedies. Poison specialists can advise you based on the product, amount, timing, age, symptoms, and other health information.

Yellow oleander poisoning symptoms

Yellow oleander contains cardiac glycosides, substances that can affect the heart and nervous system. Possible effects include nausea, vomiting, diarrhea, abdominal pain, dizziness, weakness, confusion, changes in heart rhythm, and other cardiovascular or neurologic problems.

Symptoms can vary by product and amount, and a person may not know how much yellow oleander was present. That is why feeling fine immediately after taking a product does not prove that there is no risk. If you suspect exposure, contact a poison centre or health care professional promptly rather than waiting for symptoms to appear.

For U.S. consumers, Poison Control is available online and by phone at 1-800-222-1222. In Canada, call 911 for an emergency and contact your provincial or territorial poison centre for urgent poisoning advice.

How to report the supplement

United States

U.S. consumers can report a suspected adverse event or product problem through the FDA Safety Reporting Portal. Include the product name, seller or website, purchase date if known, lot number, photographs of the label, and a description of any symptoms. You may report as a guest, and you do not need to wait for a confirmed diagnosis before reporting a concern.

Canada

The September 17, 2026 warning is from the U.S. FDA, but Canadians who bought one of these products online or experienced a reaction can still take practical safety steps: stop using the product, seek medical or poison-centre advice when needed, and report a suspected reaction to Health Canada through the Canada Vigilance process for natural health products.

Health Canada advises consumers to provide the product label, ingredients, lot number, expiry date, and details about the reaction when available. The Canadian report does not replace urgent medical care.

Why marketplace purchases need extra caution

The FDA’s table shows that some affected products were sold through major online marketplaces, third-party sellers, independent websites, and social-commerce channels. A listing’s presence on a familiar platform does not guarantee that the contents match the label or that the seller has completed independent safety testing.

Be especially cautious with products promoted for rapid weight loss and sold under names such as tejocote root, Raiz de Tejocote, Mexican hawthorn, or Brazil seed. The FDA says it is investigating additional botanical products, including some that are not labeled as tejocote.

Do not purchase a replacement from another seller simply because the packaging looks different. Check the FDA safety alert and product database for updates, and speak with a qualified health professional before starting a weight-loss supplement.

What happens next

The FDA says its investigation is continuing and that more products may be added when testing identifies yellow oleander. The agency is also working with third-party platforms and monitoring adverse-event reports, complaints, and other information.

As of September 19, 2026, the FDA has not announced a single end date for the investigation. Consumers should treat the agency’s online safety alert as the current source for additions, recall status, and product photos.
