There is little reliable evidence to support the use of turmeric for any health condition because few clinical trials have been conducted.
Preliminary findings from animal and laboratory studies suggest that a chemical found in turmeric - called curcumin - may have anti-inflammatory, anticancer, and antioxidantantioxidanta chemical substance that prevents cellular damage from free radicals properties, but these findings have not been confirmed in people.
NCCAM-funded investigators have studied the active chemicals in turmeric and their effects - particularly anti-inflammatory effects - in people to better understand how turmeric might be used for health purposes. NCCAM is also funding basic research studies on the potential role of turmeric in preventing acute respiratory distress syndrome, liver cancer, and postmenopausal osteoporosis.
