Background

• Podophyllum gets its name from the Greek words podos and phyllon, meaning foot shaped leaves. Podophyllum rhizomes have a long medicinal history among native North American tribes who used a rhizome powder as a laxative or an agent that expels worms (anthelmintic). A poultice of the powder was also used to treat warts and tumorous growths on the skin.
• Podophyllotoxin is a plant-derived compound used to produce two cytostatic drugs, etoposide and teniposide. The substance has been primarily obtained from the American mayapple (Podophyllum peltatum). The Himalayan mayapple (Podophyllum hexandrum or Podophyllum emodi) contains this constituent in a much greater quantity, but is endangered in the wild.
• Currently, extracts of the podophyllum plant are used in topical medications for genital warts, HIV-related oral hairy leukoplakia, and some skin cancers. Preliminary research also shows that CPH 82, an oral form of Podophyllum emodi composed of two purified semisynthetic lignan glycosides, may be useful in treating rheumatoid arthritis. However, when used orally, podophyllum can be lethal and should be avoided. The drug etoposide (VePesid®) is the semisynthetic derivative of podophyllotoxin, and is approved by the U.S. Food and Drug Administration (FDA) for various types of cancer.
