Small warning about curcumin--it is a blood thinner. My daughter tried this one day and the next morning she awoke with two black eyes. Watch the dosage, especially if you also take fish oil, which also thins the blood.
Ginger also thins the blood... I put a few slivers of ginger in my boiling water that I add to my chamomile tea. Great taste... drink it couple of times a week now.
