Oleander extract (Nerium oleander)

Tier 4 — risky / avoid · Cardiac glycoside toxicity · Lethal · Cancer fraud

All parts of the oleander plant contain cardiac glycosides (oleandrin) that are lethal at small doses. Promoted fraudulently as a cancer treatment despite zero clinical evidence. A single leaf can kill a child. Causes fatal cardiac arrhythmias, vomiting, and multi-organ failure. The supplement Anvirzel containing oleander extract was denied FDA approval. Oleandrin was briefly promoted during COVID-19 with no evidence.

Dose: NO safe dose — a single oleander leaf can be lethal; all products containing oleander extract should be avoided
