Turmeric is a rhizomatous herbaceous perennial plant, in the ginger family (Zingiberaceae), and is also known as Curcuma longa. The herb is native to tropical South Asia, and for healthy growth needs temperatures roughly between 68 and 86 degrees farenheit, and a good amount of rainfall. The plants are annually gathered for their rhizomes (underground stems), and are re-seeded from some of those for the next crop.

In India, turmeric is readily available and has been used by many as an antiseptic for cuts, burns and bruises, and has also been used as an antibacterial agent. It is said to contain flouride, which is beneficial for teeth. In some countries, turmeric is also taken as a dietary supplement to help with stomach problems. The herb is being investigated for potential benefits in conditions of Alzheimer's disease, cancer and liver disorders. In Japan turmeric tea is a popular item in the city of Okinawa. Under the name of Avea, turmeric is sold as a treatment for depression.

The U.S. National Institutes of Health began four clinical trials for uses of curcumin (turmeric's active agent) in treatment for Alzheimer's disease, colorectal cancer, multiple myeloma and pancreatic cancer.



A study by the UCLA Veterans Affairs in 2004 suggested that curcumin might inhibit the accumulation of destructive beta amyloids in the brains of Alzheimer's disease patients, and also may be useful in breaking up existing plaques of beta amyloids. It was noted that turmeric has been used as an anti-inflammatory in a variety of ailments in India.

Some other potential or considered benefits of turmeric which need more study include treatment against: tumors, cystic fibroris, psoriasis, breast cancer, lung cancer, and pain (as a pain reliever: antinociceptive).

Turmeric side effects are not many, but may occur with use of more than the recommended doses. Doing so may cause upset stomach or other gastrointestinal problems such as diarrhea or constipation. Also, turmeric should not be taken in some situations, including if you have a bile duct blockage, a blood-clotting disorder, or stomach ulcers (or a history of them). Pregnant and nursing women should use discretion in using turmeric, as the effects in such cases are unknown.

In some Asian countries, turmeric is called kunyit or haldi. Turmeric is often misspelled, or mispronounced, as tumeric.

Aside from medical uses, turmeric is also used as a spice, in cosmetics, as a dye, and in gardening.
