podophyllotoxin on rat epididymal epithelial cells in vitro, and hence they might be developed as potential nonhormonal male contraceptives.

Podophyllotoxin is a non-alkaloid toxin lignan extracted from the roots and rhizomes of Podophyllum species which is again an antitumor agent (57-59).
During October 2005-December 2009, the patient received topical and ablative treatments for the warts (salicylic acid,
podophyllotoxin, 5-fluoruracil cream, imiquimod 5% cream, cryosurgery, surgical curettage, electrocautery, and CO2 laser therapy), but clinical improvement was not sustained.

Topical treatments include 10-20% potassium hydroxide, cryotherapy (applying liquid nitrogen for 6-9 seconds), trichloroacetic acid (35-100%), topical tretinoin and imiquimod,
podophyllotoxin (20-25%), potassium hydrochloric solution (10-30% solution) or silver nitrate (40%).
Some of the useful plant drugs include vinblastine, vincristine, Taxol,
Podophyllotoxin, camptothecin, digitoxigenin, gitoxigenin, digoxigenin, tubocurarine, morphine, codeine, aspirin, atropine, Pilocarpine, capsicum, Ellison, curcumin, artemesinin and ephedrine among others.
Jackson and Dewick (1984), for example, found that the content of
podophyllotoxin, which is isolated from podophyllin (a resin produced by species of the genus Podophyllum, commonly known as 'may-apple'), is much higher (4.3% of dry weight) in the Himalayan species Podophyllum hexandrum than in the American species P peltatum (0.25%).
