Important Disclaimer

Overview
Mayapple is a distinctive woodland plant native to eastern North America, recognizable by its large umbrella-like leaves and single white flower. The plant contains podophyllotoxin, a highly toxic compound that has been developed into important cancer-fighting drugs (etoposide and teniposide). However, the plant itself is extremely toxic — only the fully ripe yellow fruit is edible in small amounts. All other parts cause severe poisoning. This entry is for educational purposes only.
Traditional Use
HISTORICAL REFERENCE ONLY — DO NOT USE MEDICINALLY: Native American tribes used mayapple cautiously and in very small amounts for specific purposes. The Cherokee used the root as a powerful cathartic and to treat worms. The Iroquois used it for constipation and as an emetic. Some tribes used it topically for warts and skin growths. However, these uses were extremely dangerous and frequently caused poisoning. The plant was adopted by Eclectic physicians in the 19th century as a liver stimulant and cathartic, but its toxicity made it unreliable. The most significant development came in the 20th century when podophyllotoxin was isolated and used to develop etoposide and teniposide, important chemotherapy drugs still used today for lung cancer, testicular cancer, and leukemia. The ripe yellow fruit was eaten by Native Americans and early settlers as a food, though even this requires caution.
Key Active Compounds
Podophyllotoxin
HIGHLY TOXIC lignan that inhibits cell division by binding to tubulin. The basis for the chemotherapy drugs etoposide and teniposide. Causes severe toxicity when ingested or applied to skin.
Podophyllin (Podophyllum Resin)
A resin containing podophyllotoxin and related compounds. Used medically as a topical treatment for genital warts under strict medical supervision only.
Alpha and Beta Peltatin
Related toxic lignans that contribute to the plant's overall toxicity and cytotoxic effects.
Evidence-Based Benefits
NO SAFE HOME MEDICINAL USE
ContraindicatedEDUCATIONAL ONLY: Mayapple has NO safe home medicinal applications. Podophyllotoxin derivatives are used in chemotherapy and as a prescription topical treatment for genital warts, but these are pharmaceutical preparations used under strict medical supervision. The plant itself is toxic and should never be self-administered.
Pharmaceutical Significance
StrongMEDICAL USE ONLY: Podophyllotoxin from mayapple is the basis for etoposide and teniposide, important chemotherapy drugs. Podophyllin resin is used as a prescription topical treatment for genital warts. These are medical treatments, not herbal remedies.
