What is Curcumin extract?

Curcumin is a bright yellow chemical produced by Curcuma longa plants. It is the principal curcuminoid of turmeric (Curcuma longa), a member of the ginger family, Zingiberaceae. It is used as an herbal supplement, cosmetics ingredient, food flavoring, and food coloring.
Curcumin is one of three curcuminoids present in turmeric, the other two being desmethoxycurcumin and bis-desmethoxycurcumin.
Curcumin is obtained from the dried rhizome of the turmeric plant, which is a perennial herb that is cultivated extensively in south and southeast Asia.
Curcumin, a polyphenol with anti-inflammatory properties, can abate pain, depression, and other problems related to inflammation. It can also increase the body’s production of three antioxidants: glutathione, catalase, and superoxide dismutase.
