Turmeric is the spice that gives curry its yellow color.

It has been used in India for thousands of years as both a spice and medicinal herb. Recently, science has started to back up traditional claims that turmeric contains compounds with medicinal properties (1Trusted Source).

These compounds are called curcuminoids. The most important one is curcumin.

Curcumin is the main active ingredient in turmeric. It has powerful anti-inflammatory effects and is a very strong antioxidant.
