Turmeric, a plant in the ginger family, is grown commercially in Southeast Asia and India. Its rhizome (underground stem) has been used for culinary and cosmetic purposes, among others. Curcumin, a major component of turmeric, gives the spice its yellow color. The health activities of turmeric are commonly attributed to curcuminoids, which include curcumin. Historically, turmeric has been used in Chinese, Indian (e.g., Ayurvedic), Islamic, and Thai traditional medicine systems for conditions such as indigestion, the common cold, skin infections, arthritis, abdominal pain, and liver disease. Turmeric has also been used in some Indian religious ceremonies. Today, oral (taken by mouth) turmeric is promoted as a dietary supplement for a variety of conditions, including osteoarthritis, depression, allergies, itching, and high cholesterol. Topical (applied to the skin) turmeric is promoted for osteoarthritis.

Many studies have been conducted on the safety and usefulness of turmeric or curcumin for nonalcoholic fatty liver disease (NAFLD), osteoarthritis, and high cholesterol or other lipid disorders. We don’t know enough to definitively conclude if turmeric or curcumin is beneficial for any health purposes. Highly bioavailable formulations of curcumin, which enhance the body’s ability to absorb the curcumin, may harm your liver.

It’s challenging to compare the available evidence on turmeric. Oral curcumin products vary in how much curcumin they actually contain, and they often contain substances from other plants, such as piperine from black pepper. Combining curcumin with piperine is one way to improve the bioavailability of curcumin. Several meta-analyses have evaluated oral turmeric or curcumin for osteoarthritis measures related to relieving knee pain and stiffness, increasing the strength of the joints, improving joint mobility, and other functions. The initial evidence is positive; higher-quality evidence is needed to reach definitive conclusions, and more research is needed to understand the impact of bioavailability on curcumin’s effects. It’s unclear whether topical curcumin ointment has an effect on pain related to knee osteoarthritis. Initial research suggests that oral turmeric or curcumin might improve some NAFLD measures, but it’s unclear which specific measures are consistently improved. Initial research suggests that turmeric or curcumin in an oral or mouthwash formulation might improve symptoms of oral mucositis (tissue swelling and irritation in the mouth) related to cancer treatment. There isn’t enough evidence to definitively conclude whether oral turmeric or curcumin has beneficial effects on other health conditions.

Conventionally formulated oral turmeric or curcumin (not modified to enhance bioavailability) is likely safe in the recommended amounts for up to 2 or 3 months. Oral turmeric can cause adverse effects such as nausea and vomiting, acid reflux, stomach upset, diarrhea, or constipation. Topical curcumin can cause hives or itching. Many curcumin products with increased bioavailability are on the market, and liver damage has been reported in some people who have consumed these bioavailable formulations. If you notice any liver damage symptoms such as fatigue, nausea, poor appetite, dark urine, or jaundice, stop consuming turmeric or curcumin products immediately and talk with your health care provider. The use of turmeric supplements during pregnancy may be unsafe. Little is known about whether it’s safe to use turmeric in amounts greater than those commonly found in food while breastfeeding.
