Curcuma longa (turmeric) owes its influence to the curcumin present in the root, a yellow pigment that consists of several substances together referred to as curcuminoids. Curcuminoids have an antioxidant effect for the maintenance of healthy cells and tissues. Curcuma can be used well to support the immune system, the liver, the nervous system, the musculoskeletal system and the digestive system.
