Health benefits of Turmeric
turmeric (Curcuma longa) is a culinary spice that spans cultures - it is a major ingredient in Indian curries, and makes American mustard yellow. But evidence is accumulating that this brightly colored relative of ginger is a promising disease-preventive agent as well, probably due largely to its anti-inflammatory action.
One of the most comprehensive summaries of turmeric studies to date was published by the respected ethnobotanist James A. Duke, Phd., in the October, 2007 issue of Alternative & Complementary Therapies, and summarized in the July, 2008, issue of the American Botanical Council publication HerbClip.
Reviewing some 700 studies, Duke concluded that turmeric appears to outperform many pharmaceuticals in its effects against several chronic, debilitating diseases, and does so with virtually no adverse side effects. Here are some of the diseases that turmeric has been found to help prevent or alleviate:
Alzheimer's disease: Duke found more than 50 studies on turmeric's effects in addressing Alzheimer's disease. The reports indicate that extracts of turmeric contain a number of natural agents that block the formation of beta-amyloid, the substance responsible for the plaques that slowly obstruct cerebral function in Alzheimer's disease.
Arthritis: Turmeric contains more than two dozen anti-inflammatory compounds, including sixdifferent COX-2-inhibitors (the COX-2 enzyme promotes pain, swelling and inflammation; inhibitors selectively block that enzyme). By itself, writes Duke, curcumin - the component in turmeric most often cited for its healthful effects - is a multifaceted anti-inflammatory agent, and studies of the efficacy of curcumin have demonstrated positive changes in arthritic symptoms.
Cancer: Duke found more than 200 citations for turmeric and cancer and more than 700 for curcumin and cancer. He noted that in the handbook Phytochemicals: Mechanisms of Action, curcumin and/or turmeric were effective in animal models in prevention and/or treatment of colon cancer, mammary cancer, prostate cancer, murine hepatocarcinogenesis (liver cancer in rats), esophageal cancer, and oral cancer. Duke said that the effectiveness of the herb against these cancers compared favorably with that reported for pharmaceuticals.
How can you get more turmeric into your diet? One way is via turmeric tea. There are also extracts in tablet and capsule form available in health food stores; look for supercritical extracts in dosages of 400 to 600 mg, and take three times daily or as directed on the product.
And, of course, one can simply indulge in more curried dishes, either in restaurants or at home. However you do it, adding turmeric to your diet is one of the best moves toward optimal health you can make.
Here are some of the benefits when ingested with your food as a spice:
It is a natural antiseptic and antibacterial agent, useful in disinfecting cuts and burns.
When combined with cauliflower, it has shown to prevent prostate cancer and stop the growth of existing prostate cancer.
Prevented breast cancer from spreading to the lungs in mice.
It may prevent melanoma and cause existing melanoma cells to commit suicide.
Reduces the risk of childhood leukemia.
It's a natural liver detoxifier.
Turmeric may prevent and slow the progression of Alzheimer’s disease by removing amyloyd plaque buildup in the brain.
It may prevent metastases from occurring in many different forms of cancer.
It is a potent natural anti-inflammatory that works as well as many anti-inflammatory drugs but without the side effects.
Has shown promise in slowing the progression of multiple sclerosis in mice.
Is a natural painkiller and cox-2 inhibitor.
May aid in fat metabolism and help in weight management.
Has long been used in Chinese medicine as a treatment for depression.
Because of its anti-inflammatory properties, it is a natural treatment for arthritis and rheumatoid arthritis.
Boosts the effects of chemo drug paclitaxel and reduces its side effects.
Promising studies are underway on the effects of turmeric on pancreatic cancer.
Studies are ongoing in the positive effects of turmeric on multiple myeloma.
Has been shown to stop the growth of new blood vessels in tumors.
Speeds up wound healing and assists in remodeling of damaged skin.
May help in the treatment of psoriasis and other inflammatory skin conditions.
Curcumin seems to delay liver damage that can eventually lead to cirrhosis, according to preliminary experimental research at the Medical University Graz in Austria.
Kansas State University research found that adding certain spices, including turmeric, can reduce the levels of heterocyclic amines — carcinogenic compounds that are formed when meats are barbecued, boiled or fried — by up to 40 percent.
Rodent studies at the University of Texas indicate that curcumin inhibits the growth of a skin cancer, melanoma and also slows the spread of breast cancer into the lungs.
Researchers from the University of South Dakota have found that pretreatment with curcumin makes cancer cells more vulnerable to chemo and radiotherapy.
Epidemiologists have hypothesized that the turmeric that is part of daily curries eaten in India may help explain the low rate of Alzheimer’s disease in that country. Among people aged 70 to 79, the rate is less than one-quarter that of the United States. (Source: Dr. Andrew Weil)
