Used in India and China for thousand years, but now has been discovered by scientist to have several cancer-fighting properties due to its powerful antioxidant character that maybe: 
5 to 8 times stronger than Vitamin E (and also stronger than Vitamin C) and  3 times more powerful than grape seed or pine bark extract.The orange pigment, curcumin, is the pharmacological agent.  Turmeric seems to favorably affect many medical conditions:
* Irritable Bowel  
   Syndrome
* Rheumatoid Arthritis
* Cancer Prevention
* Cancer Growth Restriction
* Alzheimer’s Disease
* Cystic Fibrosis
* Prevent Heart Disease
* Lowers cholesterol
Turmeric is perhaps the most legitimate of the so-called superfoods. 
The curcumin in turmeric is thought to work because it is a strong anti-inflammatory agent.
