OTHER NAMES Indian saffron, curcuma, haridra, jianghuang, kyoo, ukon

PART USED Root and Rhizome

USES

* Primary uses: Inflammation, bursitis, arthritis, low back pain

* Uses approved by the German Commission E: Turmeric tea is approved for dyspepsia (indigestion), especially in association with gall bladder dysfunction. Turmeric promotes bile production necessary for digesting dietary fat.

* Historical use: Joint pain and inflammation, indigestion, gas, constipation, poor vision, coughs, and to increase milk production.

* Other uses: Numerous medical studies indicate that turmeric has significant anti-inflammatory action, primarily due to its active constituent, curcumin. Curcumin also has potent antioxidant action and histamine-lowering effects, both of which may contribute to its anti-inflammatory activity. Curcumin has been shown to prevent platelet aggregation (clumping) associated with the development of atherosclerosis. Preliminary studies indicate curcumin may have benefits in preventing numerous cancers and cancer metastasis (spread), and it may be used to enhance the effectiveness of chemotherapy and radiation and to reduce the rate of replication of the human immunodeficiency virus (HIV). Most recently, test tube and animal studies report that curcumin has achieved promising results in the prevention and treatment of malaria.
