Oleandrin / Anvirzel / Nerium oleander Extract

Toxic oleander-derived cardiac-glycoside extract promoted for cancer and other diseases. Oleandrin and Anvirzel derive from Nerium oleander, a toxic plant. MSK notes lab anticancer activity but lacking human evidence, cardiac glycoside toxicity, contraindications with heart conditions/digoxin-like effects, and that these products are not approved cancer treatments. PROS Cardiac glycoside biology has laboratory anticancer interest.
