Turmeric is a relative of the ginger plant that has been used in traditional medicine. Modern science has begun investigating turmeric for medicinal properties including antioxidant and anti-inflammatory activity as well as an aid in digestion. Though turmeric is generally considered safe, interactions with some medications and medical conditions are possible.
About Turmeric
Roots or rhizomes of the turmeric plants are ground into a bright yellow powder with a warm, bitter taste that is used in many seasonings including curry powder. Curcumin is a polyphenol that gives turmeric its yellow color that has been shown to inhibit the COX2 enzyme that is involved in inflammation, and to stimulate cells to produce the endogenous antioxidant glutathione. Curcumin also induces the digestive system to increase production of bile and stomach acid, which can help treat indigestion and other digestive disorders.
Blood Thinners
Turmeric may inhibit the clotting of blood. If you are taking blood thinners including daily aspirin, warfarin or any others, consult with your health care provider before you take turmeric supplements. Your doctor may advise you to avoid turmeric or adjust your dosage of blood thinners accordingly. A combination of turmeric and blood thinners may raise the risk of excessive bleeding or other dangerous side effects.
Drugs Controlling Stomach Acid
Turmeric stimulates your digestive system to increase the production of stomach acid and bile. While this can be beneficial in promoting proper digestion and removal of waste, it will interfere with medications that inhibit stomach acid production, such as those used to treat acid reflux. Turmeric may also worsen stomach ulcers.
Other Interactions
Turmeric can aid in the lowering of blood sugar in diabetics, but may lower blood sugar excessively when combined with medications design to lower blood sugar. Some turmeric supplements contain piperine, an extract of black pepper, to increase absorption by inhibiting breakdown of drugs in the stomach. This may increase the effectiveness of other medications or supplements. As a general rule, consult with your health care provider before you take medicinal amounts of turmeric if you are taking medication daily or being treated for any medical condition.
