Some products included in the warning are branded as weight loss supplements. MDHHS is issuing this alert because many products are still available online.

- Consumers can also contact the Michigan Poison and Drug Information Center. The Michigan Poison and Drug Information Center can provide access to 24-hour emergency advice and information related to poisonings at 1-800-222-1222.
Background:
Yellow oleander is a poisonous plant native to Mexico and Central America and is considered a toxic substance. Ingestion can cause severe health effects involving the nervous, gastrointestinal and cardiovascular systems, and can result in death.
All products analyzed by the FDA were sold online through various vendors, including Amazon, eBay and Etsy. Based on information available, it is unknown if products can be found in stores in Michigan. The FDA is continuing to identify and test suspect products as part of its surveillance efforts.
