Research

What the research says

Curcumin has antioxidant properties that may help reduce inflammation in the body. Inflammation may lead to the development of cancer. There isn’t enough evidence to say that curcumin definitively prevents or treats cancer. Some research on the subject has been promising, though.

A 2009 study found that curcumin can kill many types of cancer cells in multiple ways. Because more than one method is possible, cancer cells are less likely to become curcumin-resistant. Curcumin targets only cancer cells, leaving healthy cells unaffected. This is an important step in potential treatment because chemotherapy drugs kill both healthy cells and cancer cells.

A 2008 study concluded that curcumin can help fight pancreatic cancer cells, but higher levels are needed. To address this problem, a highly bioavailable form of curcumin, called Theracurmin, was created. The widely available supplement is meant to deliver higher levels of curcumin to people with cancer without increased harm. More research is needed on people with pancreatic and other cancers to determine Theracurmin’s effectiveness.

Research has also looked at turmeric, which contains curcumin, as a way of preventing cancer. According to the Memorial Sloan Kettering Cancer Center, rats exposed to cancer-causing substances and then treated with turmeric didn’t develop stomach, colon, or skin cancers.

Risk factors

Risks and warnings

Drug interactions

Some evidence suggests turmeric may interfere with chemotherapy drugs. This is particularly true of the drugs doxorubicin and cyclophosphamide. If you’re undergoing chemotherapy, you should talk to your doctor before using turmeric or curcumin.

Turmeric can increase the amount of stomach acid in your body. So it may reduce the effectiveness of acid-reducing medications. This includes medication for acid reflux.

If you have diabetes and are taking medication to lower your blood sugar levels, turmeric can amplify the effects of your medication. Taking turmeric may cause your blood sugar to drop to a dangerously low level.

The spice can also amplify the effects of blood-thinning medications. This can increase your risk for bleeding.

Gastrointestinal

Most people can use turmeric as a culinary spice without having any side effects. However, consuming large amounts of the spice or its extract may cause you to have indigestion or an upset stomach. You may also feel nauseous or have gas.

Using turmeric for an extended period of time may cause ulcers. This is due to the increase in stomach acid.

Worsening of certain conditions

If you have gallstones or another bile-blocking condition, you should speak with your doctor before adding turmeric to your treatment plan. The spice may cause kidney stones, especially in people who are already at risk for kidney stones.

Turmeric may also affect medications, treatments, or conditions not listed here. Check with your doctor and discuss any possible risks before adding it to your regimen.
