A stomach disorder called gastroesophageal reflux disease (GERD): Turmeric can cause stomach upset in some people. It might make stomach problems such as GERD worse. Do not take turmeric if it worsens symptoms of GERD.



Hormone-sensitive condition such as breast cancer, uterine cancer, ovarian cancer, endometriosis, or uterine fibroids: Turmeric contains a chemical called curcumin, which might act like the hormone estrogen. In theory, turmeric might make hormone-sensitive conditions worse. However, some research shows that turmeric reduces the effects of estrogen in some hormone-sensitive cancer cells. Therefore, turmeric might have beneficial effects on hormone-sensitive conditions. Until more is known, use cautiously if you have a condition that might be made worse by exposure to hormones.
