PC-SPES found to contain two more drugs

Samples of the herbal prostate cancer treatment PC-SPES manufactured between 1996 and 1999 have been found to contain the arthritis drug indomethacin and diethylstilbestrol, as well as the anticoagulant warfarin. Diethylstilbestrol was the original medical treatment for prostate cancer and was very effective but was stopped because it was associated with deep-vein thrombosis. In February, the manufacturer voluntarily recalled its PC-SPES after the California Department of Health found that it contained warfarin.
