Turmeric, also known as Indian saffron or “yellow ginger”, is a perennial with yellow flowers that is native to Southeastern Asia.1 Currently, turmeric is cultivated in India, China, Japan, Indonesia, Taiwan, Africa, and other tropical countries,2 with India being responsible for the majority of turmeric production.1 The rhizomes (lateral fleshy roots) are dried and ground into a golden yellow powder used in cooking and medicine.1,2
Traditional medicinal practices in India and China tout the benefits of this bitter tasting and slightly fragrant root as a digestive aid,3 but many Ayurvedic (traditional Indian medicine) healers also integrate the powder into a paste or lotion for the treatment of dry and flaking skin, skin sores and wounds, and external inflammations.1,2,4 Other traditional internal uses of turmeric include relief of menstrual pain and treatment of urinary tract problems.1,4
Turmeric is incorporated into teas and is a base component in many culinary spice blends, specifically curry.1,2 Due to its brilliant color, turmeric has also been traditionally employed as a dye to color not only foods but cosmetics, paper, wood, and fabrics, specifically the golden robes worn by Thai Buddhist monks.4
The German Commission E approved turmeric for the internal treatment of indigestion.1
