Turmeric is a derivative of the Curcuma longa plant root. Turmeric is an ingredient common in traditional Indian spices used for cooking. The active ingredient is curcumin, which is responsible for the peppery, bitter taste and aroma you notice in curry powder. In addition, turmeric adds the yellow color to some mustards, has dye properties and is used for medicinal purposes.
