I take 1 tsp of Turmeric with water once a day. I normally use just buy the spice in a box from the food store (although from now on I will take Organic Turmeric).
I am not sure why it works. You will find that your gums are much pinker and your tongue won't have the thick white coating.
I was taking it for my memory as a preventative for old age..but since I have found it has lots of other benefits. It is fantastic for your skin, just by taking it internally as above.
