Recalled tejocote weight-loss pills contain toxic yellow oleander plant

Global Mix Inc. recalled two of its Niwali-brand tejocote weight-loss products on September 21, 2026, after Food and Drug Administration testing found the capsules and pieces actually contained yellow oleander, a plant whose toxins can disrupt heart rhythm badly enough to kill. The recalled items are Niwali Tejocote Capsules, 90-count, lot RM500925, and Niwali Tejocote Pieces, a 90-day supply, lot RM400925, both expiring March 3, 2028.

The company, based in Middle Village, New York, distributed the products nationwide through eBay and Everymarket.com, though the FDA recall notice puts total sales at just five units, two capsule packages and three pieces packages. No illnesses had been reported as of the recall.

How a hawthorn root became a cardiac poison

Tejocote root comes from Crataegus mexicana, the Mexican hawthorn, and has a long history in Hispanic households as a home remedy for coughs and digestive complaints, according to a National Capital Poison Center overview of the supplement category. It has no proven weight-loss effect. The danger comes from what keeps turning up in its place: yellow oleander, or Thevetia peruviana, a plant the FDA’s recall notice warns is dangerous down to its roots: “All parts of the yellow oleander plant are known to contain cardiac glycosides, which are highly toxic to humans and animals.” The recall notice lists the possible symptoms in people who ingest it as nausea, vomiting, dizziness, diarrhea, abdominal pain, changes in heart rhythm and arrhythmia.

Cardiac glycosides work by interfering with the electrical signaling that keeps a heartbeat steady, the same broad mechanism behind prescription heart drugs like digoxin, except delivered in an unmeasured dose inside a supplement marketed as a diet aid rather than a cardiac medication under a doctor’s supervision. That mismatch between what a bottle promises and what a lab finds inside it is the recurring thread running through nearly every tejocote enforcement action the FDA has taken.

The scale of the substitution problem is not new, and it is not small. A 2023 report in the CDC’s Morbidity and Mortality Weekly Report tested ten products purchased as tejocote root and found nine of them contained toxic yellow oleander with no authentic tejocote at all. That report centered on a 23-month-old child who was hospitalized with a slowed heart rate, low blood pressure and an ECG pattern doctors described as consistent with cardenolide toxicity, treated with digoxin-specific antibody fragments because the plant’s glycosides mimic that heart medication closely enough to complicate diagnosis.

A widening FDA list and a brand that has recalled before

Niwali’s September products are not an isolated case even within the FDA’s own recent enforcement. The agency’s running warning list of yellow oleander-contaminated products has grown to 27 items sold under brand names including Niwali, Easy Forte, Slim Elixir, D Magic Plus, B. Magi, Chupa Panza, SdB Elite and VidaSlim, with additions made progressively since the CDC’s initial 2023 report triggered FDA testing of the category. Some of those other products carry their own separate hazards: D Magic Plus was found to contain the drug diclofenac, and B. Magi tested positive for phenolphthalein, a compound linked to increased cancer risk.

Global Mix Inc. specifically has been here before. The company recalled tejocote products under four brand names, Niwali, Eva Nutrition, Science of Alpha and NWL Nutra, in April 2024 after its own testing turned up yellow oleander, according to Medical Daily’s account of the company’s recall history. The new recall covers different lot codes discovered through FDA sampling collected June 19, 2026, roughly two years after the first incident, and the company has not publicly explained how the same brand ended up contaminated again.

What buyers of the recalled lots should do

Anyone holding Niwali Tejocote Capsules lot RM500925 or Niwali Tejocote Pieces lot RM400925 is being told to stop using them immediately. The FDA notice directs consumers with questions to Global Mix Inc.’s customer service line, and anyone who has experienced an adverse reaction after taking the products to report it through the FDA’s MedWatch program.

The CDC report’s broader recommendation extends past this single recall: clinicians treating unexplained bradycardia or arrhythmia should ask patients specifically about weight-loss supplement use, since a bottle labeled tejocote root offers no guarantee, based on the agency’s own testing, of what is actually inside.

That gap between label and contents is what makes online marketplaces a particular problem for this category. Unlike a pharmacy shelf, a listing on eBay or Everymarket carries no requirement that the seller verify what a third-party manufacturer put inside a capsule, and the FDA’s spot-testing model catches contamination only after products have already reached buyers. Five units is a small number in absolute terms, but the same substitution pattern has now surfaced twice under the same brand name in roughly two years, and 26 other products carrying different names have failed the same test.

What neither the company nor the FDA has said publicly is where in the supply chain the substitution keeps happening, whether at a supplier that mislabels the raw plant material or somewhere later in packaging, which leaves open the possibility that a third Niwali recall could follow the first two.
