The rhizome (root) of turmeric (Curcuma longa Linn.) has long been used in traditional Asian medicine to treat gastrointestinal upset, arthritic pain, and "low energy." Laboratory and animal research has demonstrated anti-inflammatory, antioxidant, and anti-cancer properties of turmeric and its constituent curcumin. Preliminary human evidence, albeit poor quality, suggests possible efficacy in the management of dyspepsia (heartburn), hyperlipidemia (high cholesterol), and scabies (when used on the skin).
EvidenceDISCLAIMER: These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider.
Blood clot prevention:
Early research suggests that turmeric may prevent the formation of blood clots. However, more research is needed before turmeric can be recommended for these conditions.
Several early animal and laboratory studies report anti-cancer (colon, skin, breast) properties of curcumin. Many mechanisms have been considered, including antioxidant activity, anti-angiogenesis (prevention of new blood vessel growth), and direct effects on cancer cells. Currently it remains unclear if turmeric or curcumin has a role in preventing or treating human cancers. There are several ongoing studies in this area.
Curcumin has been shown to have antioxidant and anti-inflammatory properties and to reduce beta-amyloid and plaque burden in lab studies. However, there is currently not enough evidence to suggest the use of curcumin for cognitive performance.
Turmeric has been traditionally used to treat stomach problems (such as indigestion from a fatty meal). There is preliminary evidence that turmeric may offer some relief from these stomach problems. However, at high doses or with prolonged use, turmeric may actually irritate or upset the stomach. Reliable human research is necessary before a recommendation can be made.
Gallstone prevention/bile flow stimulant:
It has been said that there are fewer people with gallstones in India, which is sometimes credited to turmeric in the diet. Early studies report that curcumin, a chemical in turmeric, may decrease the occurrence of gallstones. However, reliable human studies are lacking in this area. The use of turmeric may be inadvisable in patients with active gallstones.
Early studies suggest that turmeric may lower levels of low-density lipoprotein ("bad cholesterol") and total cholesterol in the blood. Better human studies are needed before a recommendation can be made.
Several laboratory studies suggest that curcumin, a component of turmeric, may have activity against HIV. However, reliable human studies are lacking in this area.
Laboratory and animal studies show anti-inflammatory activity of turmeric and its constituent curcumin. Reliable human research is lacking.
Irritable bowel syndrome (IBS):
Irritable bowel syndrome (IBS) is a common functional disorder for which there are limited reliable medical treatments. One study investigated the effects of Curcuma xanthorriza on IBS and found that treatment did not show any therapeutic benefit over placebo. More studies are needed to verify these findings.
In traditional Indian Ayurvedic medicine, turmeric has been used to tone the liver. Early research suggests that turmeric may have a protective effect on the liver, but more research is needed before any recommendations can be made.
Results from lab and animal studies suggest turmeric may have anticancer effects. Large, well-designed human studies are needed before a recommendation can be made.
Turmeric has been used historically to treat rheumatic conditions. Laboratory and animal studies show anti-inflammatory activity of turmeric and its constituent curcumin, which may be beneficial in people with osteoarthritis. Reliable human research is lacking.
Peptic ulcer disease (stomach ulcer):
Turmeric has been used historically to treat stomach and duodenal ulcers. However, at high doses or with prolonged use, turmeric may actually further irritate or upset the stomach. Currently, there is not enough human evidence to make a firm recommendation.
Turmeric has been used historically to treat rheumatic conditions and based on animal research may reduce inflammation. Reliable human studies are necessary before a recommendation can be made in this area.
Historically, turmeric has been used on the skin to treat chronic skin ulcers and scabies. It has also been used in combination with the leaves of the herb Azadirachta indica ADR or "neem." More research is necessary before a firm recommendation can be made.
Uveitis (eye inflammation):
Laboratory and animal studies show anti-inflammatory activity of turmeric and its constituent curcumin. A poorly designed human study suggests a possible benefit of curcumin in the treatment of uveitis. Reliable human research is necessary before a firm conclusion can be drawn.
Evidence suggests that turmeric may help treat viral infections. However, there is not enough human evidence in this area. Well-designed trials are needed to determine if these claims are true.
TraditionWARNING: DISCLAIMER: The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below.

Adults (over 18 years old)
Doses used 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.
One reported method for treating scabies is to cover affected areas once daily with a paste consisting of a 4:1 mixture of Azadirachta indica ADR ("neem") to turmeric, for up to 15 days. Scabies should be treated under the supervision of a qualified healthcare professional.
Children (under 18 years old)
There is no proven or safe medicinal dose of turmeric in children.
SafetyDISCLAIMER: Many complementary techniques are practiced by healthcare professionals with formal training, in accordance with the standards of national organizations. However, this is not universally the case, and adverse effects are possible. Due to limited research, in some cases only limited safety information is available.
Allergic reactions to turmeric may occur, including contact dermatitis (an itchy rash) after skin or scalp exposure. People with allergies to plants in the Curcuma genus are more likely to have an allergic reaction to turmeric. Use cautiously in patients allergic to turmeric or any of its constituents (including curcumin), to yellow food colorings, or to plants in the Zingiberaceae (ginger) family.
Side Effects and Warnings
Turmeric may cause an upset stomach, especially in high doses or if given over a long period of time. Heartburn has been reported in patients being treated for stomach ulcers. Since turmeric is sometimes used for the treatment of heartburn or ulcers, caution may be necessary in some patients. Nausea and diarrhea have also been reported.
Based on laboratory and animal studies, turmeric may increase the risk of bleeding. Caution is advised in patients with bleeding disorders or taking drugs that may increase the risk of bleeding. Dosing adjustments may be necessary. Turmeric should be stopped prior to scheduled surgery.
Limited animal studies show that a component of turmeric, curcumin, may increase liver function tests. However, one human study reports that turmeric has no effect on these tests. Turmeric or curcumin may cause gallbladder squeezing (contraction) and may not be advised in patients with gallstones. In animal studies, hair loss (alopecia) and lowering of blood pressure have been reported. In theory, turmeric may weaken the immune system and should be used cautiously in patients with immune system deficiencies.
Turmeric should be used with caution in people with diabetes or hypoglycemia or people taking drugs or supplements that lower blood sugar.
Pregnancy and Breastfeeding
Historically, turmeric has been considered safe when used as a spice in foods during pregnancy and breastfeeding. However, turmeric has been found to cause uterine stimulation and to stimulate menstrual flow and caution is therefore warranted during pregnancy. Animal studies have not found turmeric taken by mouth to cause abnormal fetal development.
