SafetyDISCLAIMER: Many complementary techniques are practiced by healthcare professionals with formal training, in accordance with the standards of national organizations. However, this is not universally the case, and adverse effects are possible. Due to limited research, in some cases only limited safety information is available.
Allergic reactions to turmeric may occur, including contact dermatitis (an itchy rash) after skin or scalp exposure. People with allergies to plants in the Curcuma genus are more likely to have an allergic reaction to turmeric. Use cautiously in patients allergic to turmeric or any of its constituents (including curcumin), to yellow food colorings, or to plants in the Zingiberaceae (ginger) family.
Side Effects and Warnings
Turmeric may cause an upset stomach, especially in high doses or if given over a long period of time. Heartburn has been reported in patients being treated for stomach ulcers. Since turmeric is sometimes used for the treatment of heartburn or ulcers, caution may be necessary in some patients. Nausea and diarrhea have also been reported.
Based on laboratory and animal studies, turmeric may increase the risk of bleeding. Caution is advised in patients with bleeding disorders or taking drugs that may increase the risk of bleeding. Dosing adjustments may be necessary. Turmeric should be stopped prior to scheduled surgery.
Limited animal studies show that a component of turmeric, curcumin, may increase liver function tests. However, one human study reports that turmeric has no effect on these tests. Turmeric or curcumin may cause gallbladder squeezing (contraction) and may not be advised in patients with gallstones. In animal studies, hair loss (alopecia) and lowering of blood pressure have been reported. In theory, turmeric may weaken the immune system and should be used cautiously in patients with immune system deficiencies.
Turmeric should be used with caution in people with diabetes or hypoglycemia or people taking drugs or supplements that lower blood sugar.
Pregnancy and Breastfeeding
Historically, turmeric has been considered safe when used as a spice in foods during pregnancy and breastfeeding. However, turmeric has been found to cause uterine stimulation and to stimulate menstrual flow and caution is therefore warranted during pregnancy. Animal studies have not found turmeric taken by mouth to cause abnormal fetal development.
