The effect of herbal medications on thyroid hormone economy and estrogen-sensitive hepatic proteins in a patient with prostate cancer.

摘要

Nonprescription drugs such as PC-SPES (Botanic Lab) (PC, abbreviation for prostate cancer; SPES, Latin for hope)-an herbal therapy for prostate cancer-are part of the complementary and alternative medicine (CAM) approach to health. PC-SPES was removed from the US market in 2002 owing to contamination with indometha-cin, diethylstilbestrol, and warfarin.1 Yet it and similar preparations remain widely used because they are available online. Their clinical effect on nonprostatic, hormonally responsive systems has not been studied.
