Dong quai can cause skin to become extra-sensitive to the sun. This might put you at greater risk for skin cancer. Wear sun block outside, especially if you are light-skinned.
Taking dong quai in large amounts for a long period of time is POSSIBLY UNSAFE. Dong quai contains chemicals that are considered to be cancer-causing (carcinogens).
Special Precautions & Warnings:Pregnancy and breast-feeding: Taking dong quai by mouth during pregnancy is POSSIBLY UNSAFE for the baby. Dong quai seems to affect the muscles of the uterus. There is also one report linking an herbal combination that contained dong quai with birth defects in a baby whose mother took the combination during the first three months of pregnancy. Don't use dong quai if you are pregnant.
There isn't enough information about the safety of using dong quai during breast-feeding. Stay on the safe side and don't use it.
Bleeding disorders. Dong quai might slow blood clotting. In theory, dong quai might increase the risk of bruising and bleeding in people with bleeding disorders.
Hormone-sensitive conditions such as breast cancer, uterine cancer, ovarian cancer, endometriosis, or uterine fibroids: Dong quai might act like estrogen. If you have any condition that might be made worse by exposure to estrogen, don't use dong quai.
Protein S deficiency: People with protein S deficiency have an increased risk of forming blood clots. There is some concern that dong quai might increase the risk of clot formation in these people because it has some of the effects of estrogen. Don't use dong quai if you have protein S deficiency.
Surgery: Dong quai can slow blood clotting. It might increase the risk of bleeding during and after surgery. Stop taking dong quai at least 2 weeks before a scheduled surgery.
