Turmeric is a marigold-colored spice grown in India, Indonesia, China, the Philippines, Taiwan, Haiti and Jamaica and is the key ingredient in curry powder. While many herbs offer positive health
benefits, research has shown turmeric to be a stand out superstar in what it can do for your health, including that organ in your body that beats more than 100,000 times a day, your heart.
The power of turmeric
In India it's revered as "holy powder" and has been used for centuries to treat wounds, infections and other health problems. In recent years, research has shown turmeric's active
ingredient, curcumin, has anti-inflammatory, analgesic, anti-bacterial, anti-tumor, anti-allergic, antioxidant, antiseptic, antispasmodic, astringent, digestive, diuretic and stimulant properties.
That's quite a list of health benefits! What gives turmeric its healing powers?
Turmeric has effects that go deep into the nucleus of cells (the nucleus is the information center of the cell), something far beyond what most herbal remedies can do. University of Michigan
researchers led by chemistry and biophysics professor Ayyalusamy Ramamoorthy found that curcumin acts as a "disciplinarian" in the cells, making them more orderly and improving
cells' resistance to infection and malignancy. "The membrane goes from being crazy and floppy to being more disciplined and ordered, so that information flow through it can be controlled,"
explains Dr Ramanoorthy.
Turmeric and Heart Health
The February 2008 Journal of Clinical Investigation reported the findings of an animal study that found curcumin may prevent and reverse cardiac hypertrophy, a condition characterized by
the heart muscle being abnormally enlarged. Cardiac hypertrophy often accompanies long term high blood pressure and congestive heart failure. Further, cardiac hypertrophy is a strong predictor of
future cardiac problems, including heart attack and heart failure. If clinical trials in humans prove curcumin is effective, it may offer an inexpensive and safe treatment for millions.
While the results of the 2008 study are promising, they were conducted in lab rats and not humans. Dr. Liu, a lead researcher in the study suggests proceeding with moderation, "Whether you
are young or old; male or female; the larger your heart is, the higher your risk is for developing heart attacks or heart failure in the future. However, until clinical trials are done, we
don't recommend patients to take curcumin routinely. You are better off to take action today by lowering blood pressure, reducing cholesterol, exercising and healthy eating."
Be cautious with curry
If you want to include curcumin in your diet and enjoy experimenting with flavors, turmeric has a warm, peppery, woodsy, earthy flavor that can be added to a number of recipes including chicken,
beans, bread, butter pickles and numerous vegetable combinations.
You may even already unknowingly consume turmeric. Turmeric gives yellow mustard its bright color and in addition to its central role in curry power, it's a key ingredient in Worcestershire
sauce. It's also used to color foods such as butter, cheese and fruit drinks. Be sure to buy pure turmeric powder rather than curry powder; one study showed curry contains very little of the
active ingredient curcumin.
It seems whenever research suggests a spice or herb may be beneficial for health, the supplement industry is quick to turn this "health-promoting" substance into pills, powders or
liquids. Though experts suggest consuming whole foods, if you decide to supplement, do so wisely.
Turmeric supplements for adults (over 18 years old)
According to the National Institute of Health, doses range from 450 milligrams of curcumin capsules to 3 grams of turmeric root daily, divided into several doses, taken by mouth. As a tea, 1 to 1.5
grams of dried root may be steeped in 150 milliliters of water for 15 minutes and taken twice daily. Average dietary intake of turmeric in the Indian population may range between 2 to 2.5 grams,
corresponding to 60 to 200 milligrams of curcumin daily. A dose of 0.6 milliliters of turmeric oil has been taken three times daily for one month and a dose of 1 milliliter in three divided doses
has been taken for two months. Before you supplement, talk to your doctor.
Turmeric supplements for children (under 18 years old)
There is no proven or safe medicinal dose of turmeric in children.
Safety of Turmeric
The FDA classifies turmeric as GRAS (General Recognition of Safety). Studies show that curcumin even in large quantities produces few, if any, side effects in humans. However, allergic reactions
may include contact dermatitis (an itchy rash) after skin or scalp exposure.
People allergic to plants in the Curcuma genus are more likely to have an allergic reaction to turmeric. Use caution if you are allergic to any of its constituents, yellow food colorings, or to
plants in the ginger family. Turmeric may cause an upset stomach or heart burn in high doses or over a long period of time. Pregnant women and individuals with gallstones or bleeding disorders
should speak with a health care provider before using turmeric.
