Tejocote supplements sold online at Amazon, Etsy may contain fatal poison: FDA

Tejocote weight-loss supplements sold through online through Amazon or Etsy could contain a highly toxic substance, the U.S. Food and Drug Administration is warning.

FDA tests revealed that capsules labeled as tejocote instead contained yellow oleander, a poisonous plant native to Mexico and Central America.

The FDA found yellow oleander in nine different products labeled as tejocote agency said. Those products were purchased through Amazon, Etsy, and online natural food or supplement retailers.

According to the FDA warning, the adulterated products included Alipotec Tejocote Root, Nutraholics ELV Tejocote Root, ELV Nutraholics Mexican Tejocote Root, ELVPOTEC Tejocote Root, Science of Alpha Mexican Tejocote Root, Niwali Raiz de Tejocote, Alipotec Tejocote Root, Tejocotex and ELV Alipotec Raiz de Tejocote, the FDA said.

"Ingestion of yellow oleander can cause neurologic, gastrointestinal and cardiovascular adverse health effects that may be severe, or even fatal," the FDA said in its official warning. Symptoms may include nausea, vomiting, dizziness, diarrhea, abdominal pain, and heart rhythm problems, the agency noted.

Tejocote, also known as Mexican hawthorn root, has been promoted through social media for weight loss, according to the U.S. Centers for Disease Control and Prevention.

Concerns about the supplement arose in September 2022 after a 23-month-old New Jersey toddler developed nausea, vomiting, slowed heart rate and low blood pressure after getting into the mom's tejocote capsules, according to a CDC report issued in September 2023.

The New Jersey Poison Information and Education System subsequently purchased 10 different tejocote products online and found that nine of the 10 contained yellow oleander, the CDC report said.

The FDA says it is concerned that there are more products touted as tejocote that instead contain yellow oleander.

Tejocote also is sold under other names, including Crataegus mexicana, Raiz de Tejocote, and Mexican Hawthorn, the FDA said.
