Turmeric is the spice that gives curry its yellow colour. The dried root of the Curcuma longa plant is ground into the distinctive yellow turmeric powder. It has been used in India for thousands of years as a spice and medicinal herb. Recently, science has started to back up what Indians have known for a long time — it really does contain compounds with medicinal properties. The potential health benefits of curcumin include better regulation of inflammation. It is used in the treatment of numerous inflammatory conditions for its anti-inflammatory effects.
