Tumeric curcumin is found in the tumeric plant that is native to southern Asia. As a supplement, it is used to treat indigestion, inflammation and arthritis. Most side effects are associated with its long-term use.

Side Effects

The most common side effects are nausea, diarrhea, skin rashes and a bitter aftertaste.

Time Frame

These side effects are more likely to occur after taking the supplement for an extended period of several months or years, according to the Physicians Desktop Reference.

Allergic reaction

An allergic reaction to tumeric curcumin can cause shortness of breath, wheezing, hives and chest pain.


In rare cases associated with long-term use, tumeric curcumin contributes to the formation of ulcers in the stomach.


When combined with blood-thinning medications like warfarin or heparin, tumeric curcumin increases the risk of excessive bleeding following an injury, dental work or surgery, according to RxList.


If you have a history of gallbladder disease, are pregnant or nursing, or scheduled to have surgery within 14 days, avoid taking tumeric curcumin supplements.
