The ripe fruit of Podophyllum peltatum is considered edible; all other parts of the plant are toxic. Several lignans and their glycosides, present in the resin extracted from rhizomes and roots, exhibit antitumor activity. Etoposide, a semisynthetic derivative of one of the lignans, is currently used in the treatment of small-cell lung cancer and testicular cancer (P. M. Dewick 1983). Native Americans used Podophyllum for a wide variety of medicinal purposes and as an insecticide (D. E. Moerman 1986).
Podophyllum peltatum is sometimes cultivated in woodland gardens, and some populations on the periphery of its geographical range may be escapes from cultivation.
