Turmeric (Curcuma longa) is an herb of the ginger family that is native to southern Asia and cultivated extensively in India, China, Indonesia, and other tropical countries. Turmeric is the main spice in curry and contains a natural yellow-colored pigment called curcumin.1 Dried turmeric rhizomes are ground and made into a soluble powder. Turmeric has long been used for inflammatory conditions and liver support.
Turmeric extract may help ease osteoarthritis pain due to its anti-inflammatory property.1,2 It has been also used for digestive complaints, such as dyspepsia.3 It has been suggested in human and preclinical studies that Turmeric may protect the liver by reducing a liver enzyme associated with liver problems (ALA: alanine transaminase) and alcohol induced fatty liver.4,5 Turmeric supplementation may also protect the kidneys by lowering urinary protein excretion and substances increasing inflammation (e.g., proinflammatory cytokines) in diabetic patients.6
