The FDA has completed analytical testing of additional products that tested positive for yellow oleander, a toxic substance. These yellow oleander containing products have been added to this Safety Alert. The complete list of products can be found in the chart below.
The agency is reminding consumers to avoid these products because they contain toxic yellow oleander and can cause neurologic, gastrointestinal and cardiovascular adverse health effects that may be severe, or even fatal.
What is the problem?
FDA analysis has determined that certain products labeled as tejocote (Crataegus mexicana) root or Brazil seed are adulterated because they contain yellow oleander (Thevetia peruviana) instead of the labeled ingredients. Yellow oleander is a poisonous plant native to Mexico and Central America and a toxic substance of concern to public health officials.
Recommendations for consumers
The FDA is advising consumers to stop using and dispose of these products.
The FDA advises consumers who have taken any of these products to contact their health care provider immediately, even if the products have not been used recently, so that an appropriate evaluation may be conducted.
Call 9-1-1 or get emergency medical help right away if you or someone in your care has serious side effects from these products.
Consumers can also contact the state poison control center.Tested Products
The FDA is continuing to identify and test suspect products as part of our surveillance efforts. The products listed [in the table at the link] have been found to contain yellow oleander.
Summary and Scope of the Problem
In September 2023, the Centers for Disease Control and Prevention published a report of several tejocote root products found to be substituted with yellow oleander, a toxic substance. Based on this report, the FDA initiated an investigation to sample and test additional tejocote root products. As part of FDA’s ongoing surveillance sampling efforts, we continue to test products; those found to contain yellow oleander are listed above.
Based on the FDA’s sampling and testing results thus far, the FDA is also concerned that other products marketed as tejocote root (including with other names such as Crataegus mexicana, Raiz de Tejocote, and Mexican Hawthorn) may contain yellow oleander. Consuming yellow oleander can cause severe adverse health effects and be potentially fatal.
Actions
The FDA is actively working with the third-party platforms where these products are sold.
The FDA’s investigation is ongoing, and the FDA will continue to provide information on any further actions as it becomes available. Products may be added to this advisory. The FDA is working to further address the concerns related to these products and monitoring the market for adverse events, product complaints, and other emerging issues.

The FDA continues to receive adverse event reports related to the products identified in this Safety Alert. The agency is reminding consumers to avoid these products because they contain toxic yellow oleander and can cause neurologic, gastrointestinal and cardiovascular adverse health effects that may be severe, or even fatal. The agency continues to communicate with firms selling these products. While a few have initiated voluntary recalls (please see the updates made to the table above), the FDA is concerned that products containing toxic yellow oleander remain on the marketplace. The FDA continues to evaluate additional regulatory pathways to remove all identified products from the marketplace."
The complete list of products can be found in the chart at the link. It is honestly concerning the number of companies that have either not been reached or have declined to issue a recall.
Also the FDA doesn't say this in their alert, but tejocote is marketed as a weight loss supplement. Fatphobia continues to endanger people's health, and that really feels like a missing part of this announcement.
