Natural gossypol (GP) is made up of two mirror image molecules.
(+)GP (plus gossypol) and (-)GP (minus gossypol).
There is ongoing research to use Gossypol as a natural alternative to vasectomy (permanent method of birth control). Gossypol has also long been known to possess anti-malarial properties.
The root, bark and the pigmented glands of the seeds contain gossypol, it is shown to be antiviral; the influenza virus is inactivated by it. Gossypol is also effective against herpes and seems to increase interferon levels naturally.
Interferons are proteins and part of the natural defense of the body.

Women use it against uterus disorders such as uterine bleeding, uterine myoma and endometriosis (painful disorder, tissue that lines the inside of the uterus grows outside of it).

Gossypol (actually a yellow pigment) extracted from the root and seed), has demonstrated in vitro effects on cell cycle regulation and anti-tumor activity against mammary carcinoma cell lines. The cell cycle regulatory effects of gossypol suggest a potential role for gossypol as a modulating agent in conjunction with other cell cycle specific compounds.

According to Chinese studies, gossypol is effective as a non-hormonal male contraceptive; however, it has been found to have irreversible effects on male fertility. It is now being studied for clinical applications in cancer therapies.
It has been tested for use against prostate and other cancers.
A study of the effect of gossypol on the growth of human androgen-independent prostate cancer cell line (PC3) showed gossypol to be a potent inhibitor of prostate cancer cell growth.
Gossypol has demonstrated in vitro effects on cell cycle regulation and anti-tumor activity against mammary carcinoma cell lines.

The natural form of gossypol has been extensively tested in humans and is well tolerated for long-term use.
Using the more active form, (-)GP for example, in combination with radiation or chemotherapy, it may soon find its new role in the fight against cancer.
