Gossypol is the active component extracted from cotton roots and seeds. It accounts for about 1.5% of the seeds in weight,and is mostly used as medicine in the form of Gollypol Acetate. It is a natural male contraceptive and is also used for treatment of female gynecological disorders. Clinical studies indicate that it has potent anti-tumor and anti-virus activity,and has been used for treating cancer of the adrenal cortex and cancer of the bladder.
