This is really nothing new. Ayurveda has known and used turmeric (the source of curcumin) for ages.
In 2007 USA Today mentioned a couple of interesting studies. This research suggest that curcumin could potentially be utilized for a number of conditions, not only treating inflamed joints.
“A study of more than 1,000 older men in Singapore last year found that those who ate lots of curry-spiced food did better on memory tests than those who rarely ate the spice.
The findings from Singapore suggest curry may help keep the aging brain in top shape.
But to get the proof that curcumin fights serious health conditions, researchers will have to conduct large clinical trials, and those studies will be expensive
and take years to complete.”
