a biologically active substance derived from the curcuma longa plant; found within the Indian spice called turmeric; curcumin and its curcuminoid polyphenols have anti-prostate cancer activity against both AIPC and ADPC
Curcumin is the principal curcuminoid of the Indian curry spice turmeric. The curcuminoids are polyphenols and are responsible for the yellow color of turmeric. Curcumin can exist in at least two tautomeric forms, keto and enol.
Studies have shown that curcumin can inhibit colon cancer cells by some 96% in a matter of hours. It also appears to have great potential in countering the effects of prostate cancer and breast cancer.
