In India, it was traditionally used for disorders of the skin, upper respiratory tract, joints, and digestive system. Today, turmeric is promoted as a dietary supplement for a variety of conditions, including arthritis, digestive disorders, respiratory infections, allergies, liver disease, depression, and many others.

Studies show that turmeric's good effects are based on the amount of curcumin taken. Scientists advise consuming between 500 and 1,000 milligrams of curcumin a day. Two teaspoons of fresh turmeric contain around 400 milligrams of curcumin, but this amount can vary depending on the spice's quality.
