Common cooking ingredients that act like medicines

One of my favorites for reports of possible Alzheimer's prevention:

1. Turmeric. As anyone who has ever treated a head cold with a nice hot Indian meal already knows, turmeric is one of the best healing herbs available to us today. It contains the anti-inflammatory curcumin, which may function in the same way as some pharmaceutical arthritis drugs.

The next time your joints are aching, just have a healthy serving of curry and see if your symptoms respond to the exotic spice. Researchers recommend a daily serving of 400 mg.
