FDA update: These supplements contain toxic yellow oleander

An ongoing FDA investigation into adulterated dietary supplements purchased online and labeled as relocate root finds more samples containing toxic yellow oleander—a poisonous plant that can be fatal to humans. An expanded product list is available to the public as of Dec. 3, 2024. Here’s what you should know, and what to do if you’ve taken supplements adulterated with yellow oleander.

Continued investigation of mislabeled tejocote root supplements

In September 2023, the US Food and Drug Administration issued a warning to consumers about tejocote root (Crataegusmexicana) supplements, particularly those purchased online through third-party retailers like Amazon and Etsy. An analysis conducted at that time revealed that all nine products sampled were labeled as tejocote but were actually toxic yellow oleander (Cascabela thevetia), a potentially fatal poison that can cause “neurologic, gastrointestinal, and cardiovascular adverse health effects,” including convulsions and lethargy, diarrhea, hypertension, and in severe cases, coma.  

The FDA expanded the list of adulterated tejocote supplements on Sep. 27, 2024, when the agency released analyses of additional similar products; the FDA has now tested 23 samples and found 23 contaminated with yellow oleander. 

On Dec. 3, 2024, the FDA again expanded this list to include additional products that tested positive for yellow oleander. 

“FDA is just playing a dangerous game of whack-a-mole where consumers lose,” said Jensen Jose, CSPI regulatory counsel. “Once the agency warns us about one dangerous supplement, there’s another one ready to take its place. Congress must do something to curb this out-of-control $55 billion dietary supplement market.”

The skinny on adulterated tejocote products

Tejocote root is often marketed as a weight-loss supplement and has found a surge in popularity in recent years, partly because online influencers often promote the brand name Alipotec through social media platforms. (This brand is included in the recall list below.) 

Many of the “tejocote root supplements” identified as yellow oleander were purchased through or fulfilled by Amazon. Though most product listings have been removed recently, Amazon still sells many brands of tejocote root products, which are generally accompanied by multiple customer reviews that attribute significant weight loss and other results to taking tejocote root. However, it is poorly researched for weight loss and is associated with cardiotoxicity (damage to the heart or cardiovascular system) in several case studies.  

In 2022, a 23-month-old child who consumed their mother’s weight-loss supplement was poisoned by yellow oleander that was sold as tejocote root. In its statement, the FDA says it “is also concerned that other products marketed as tejocote," including with other names such as Crataegus mexicana, Raiz de Tejocote, Mexican Hawthorn, or Brazil Seed), "may contain yellow oleander. Consuming yellow oleander can cause severe adverse health effects and be potentially fatal.” 

Supplements should be better regulated—especially online

The world of dietary supplements is a poorly regulated one, and even diligent consumers who research ingredients lists and efficacy studies can be harmed by manufacturers who omit information from product packaging. CSPI has long urged agencies and Congress to do more to protect consumers from mislabeled, untested, and illegally marketed supplements. 

In 2018, CSPI president and executive director Dr. Peter Lurie called on Congress and the FDA to better protect consumers from supplements contaminated with pharmaceutical drugs:

The agency could pick up its pace issuing warning letters and taking other enforcement actions (its last warning letter for a tainted dietary supplement was in 2009, despite detecting hundreds of tainted products since then). And Congress could require pre-market third-party testing of supplements—particularly of supplements advertised as weight loss, sex enhancement, or body building aids—to assure that they don’t contain unsafe or unlabeled ingredients.

CSPI will continue to push for state legislation that protects consumers, particularly children, from dangerous and fraudulent supplements.

If you have purchased any of these supplements, stop taking them immediately. The FDA recommends contacting your healthcare provider at once, and adds that, “Even if these products have not been used recently, consumers should still inform their healthcare provider about which product they took, so that an appropriate evaluation may be conducted.” 

If you are experiencing adverse health effects from consuming a supplement—whether it is on the list above or not—call 9-1-1 or get emergency medical help right away. If you have concerns about supplements you’ve taken, contact your healthcare provider and your state poison control center. 

When and how to dispose of adulterated supplements

Consumers who have purchased tejocote root supplements or other potentially adulterated products and suspect or experience adverse health effects can file a MedWatch Online Voluntary Reporting Form, using the Consumer/Patient portal on the linked page. Keep the product and its packaging until instructed to submit it to the FDA for assessment or throw it away. Until then, keep the product stored safely away from children and pets.

After filing a MedWatch report, you may be asked to send your remaining product to the FDA for evaluation. A representative will contact you with information if this is the case.

If you are instructed by your doctor, pharmacist, or poison control center to dispose of the product, follow the instructions provided to you. If you do not receive instructions for safe disposal, follow these steps:

1. Drop the product off at a drug take-back site. Find an authorized drug collection site near you or call the DEA Diversion Control Division Registration Call Center at 1-800-882-9539 for more information about these collection sites.
2. If a drug take-back site is not available, check the FDA flush list. Some medications, like opioids, are extremely dangerous when misused or abused. These medications are better flushed than stored where children, pets, or other adults in your home can accidentally ingest them. Search the FDA flush list for your medication and follow the guidelines when disposing of your unused medications and supplements. 
3. If you have been instructed to dispose of your product, and no take-back site is available, and your medication is not on the FDA flush list, then prepare it for disposal at home as follows:

• Mix the medicines into something unpalatable, like used coffee grounds, dirt, or even kitty litter.
• Place the mixture in a zip-top plastic bag. Consider double bagging.
• Throw the bag away in your trash at home. Do not throw it into the recycling or into public trash bins.
• If the container for your disposed product includes personal info, use a Sharpie to black out your name, address, and other identifying information, or remove and destroy the label separately.
