Turmeric

Turmeric (Curcuma longa) has been used for 4,000 years to treat a variety of conditions. Studies show that turmeric may help fight infections and some cancers, reduce inflammation, and treat digestive problems, and it has gotten a lot of press lately.

But remember several facts when you hear news reports about turmeric. First, many studies have taken place in test tubes and animals, and turmeric may not work as well in humans. Second, some studies have used an injectable form of curcumin, the active substance in turmeric. Finally, some of the studies show conflicting evidence.

Turmeric is widely used in cooking and gives Indian curry its flavor and yellow color. It is also used in mustard and to color butter and cheese. Turmeric has been used in both Ayurvedic and Chinese medicine as an anti-inflammatory, to treat digestive and liver problems, skin diseases, and wounds.

Curcumin is also a powerful antioxidant. Antioxidants scavenge molecules in the body known as free radicals, which damage cell membranes, tamper with DNA, and even cause cell death. Antioxidants can fight free radicals and may reduce or even help prevent some of the damage they cause.

In addition, curcumin lowers the levels of two enzymes in the body that cause inflammation. It also stops platelets from clumping together to form blood clots.

Research suggests that turmeric may be helpful for the following conditions:

Indigestion or Dyspepsia

Curcumin stimulates the gallbladder to produce bile, which some people think may help improve digestion. The German Commission E, which determines which herbs can be safely prescribed in Germany, has approved turmeric for digestive problems. And one double-blind, placebo-controlled study found that turmeric reduced symptoms of bloating and gas in people suffering from indigestion.

Ulcerative colitis

Turmeric may help people with ulcerative colitis stay in remission. Ulcerative colitis is a chronic disease of the digestive tract where symptoms tend to come and go. In one double-blind, placebo-controlled study, people whose ulcerative colitis was in remission took either curcumin or placebo, along with conventional medical treatment, for 6 months. Those who took curcumin had a relapse rate much lower than those who took placebo.

Stomach Ulcers

Turmeric does not seem to help treat stomach ulcers. In fact, there is some evidence that it may increase stomach acid, making existing ulcers worse. (See "Precautions" section.)

Osteoarthritis

Because of its ability to reduce inflammation, researchers have wondered if turmeric may help relieve osteoarthritis pain. One study found that people using an Ayurvedic formula of herbs and minerals with turmeric, winter cherry (Withinia somnifera), boswellia (Boswellia serrata), and zinc had less pain and disability. But it' s impossible to know whether it was turmeric or one of the other supplements -- or all of them together -- that was responsible.

Heart Disease

Early studies suggested that turmeric may help prevent atherosclerosis, the buildup of plaque that can block arteries and lead to heart attack or stroke. In animal studies, an extract of turmeric lowered cholesterol levels and kept LDL "bad" cholesterol from building up in blood vessels. Because it stops platelets from clumping together, turmeric may also prevent blood clots from building up along the walls of arteries. But a double-blind, placebo-controlled study found that taking curcumin, the active ingredient in turrmeric, at a dose of up to 4 g per day did not improve cholesterol levels.

Cancer

There has been a great deal of research on turmeric's anti-cancer properties, but results are still very early. Evidence from test tube and animal studies suggests that curcumin may help prevent or treat several types of cancers, including prostate, breast, skin, and colon cancer. Its preventive effects may be because it is a strong antioxidant, protecting cells from damage. More research is needed. Cancer should be treated with conventional medications. Don' t use alternative therapies alone to treat cancer. If you choose to use complementary therapies along with your cancer treatment, make sure you tell all your doctors.

Bacterial and Viral Infections

Test tube and animal studies suggest turmeric may kill bacteria and viruses. But researchers don' t know whether it would work in people.

Uveitis

A preliminary study suggests curcumin may help treat uveitis, an inflammation of the eye' s iris. In one study of 32 people with chronic anterior uveitis, curcumin was effective as corticosteroids, the type of medication usually prescribed. More research is needed.

Plant Description:

A relative of ginger, turmeric is a perennial plant that grows 5 - 6 feet high in the tropical regions of Southern Asia, with trumpet-shaped, dull yellow flowers. Its roots are bulbs that also produce rhizomes, which then produce stems and roots for new plants. Turmeric is fragrant and has a bitter, somewhat sharp taste. Although it grows in many tropical locations, the majority of turmeric is grown in India, where it is used as a main ingredient in curry.

Parts Used:

The roots, or rhizomes and bulbs, are used in medicine and food. They are generally boiled and then dried, turning into the familiar yellow powder. Curcumin, the active ingredient, has antioxidant properties. Other substances in this herb have antioxidant properties as well.

Available Forms:

Turmeric is available in the following forms:

• Capsules containing powder
• Fluid extract
• Tincture

Because bromelain increases the absorption and anti-inflammatory effects of curcumin, it is often combined with turmeric products.
