Dong Quai Root

Dong quai is used for menstrual cramps, premenstrual syndrome (PMS), and menopausal symptoms. It is also used orally as a "blood purifier"; to manage hypertension, infertility, joint pain, ulcers, "tired blood" (anemia), and constipation; and in the prevention and treatment of allergic attacks. Dong quai is also used orally for the treatment of loss of skin color (depigmentation) and psoriasis.

Some men apply dong quai to the skin of the penis as part of a multi-ingredient preparation for treating premature ejaculation.
Heart disease. Early research suggests that injecting a specific product containing dong quai, ginseng, and astragalus (Yi-qi Huo-xue Injection) intravenously (by IV) reduces chest pain, improves heart function, and increases exercise tolerance in people with heart disease.
Stroke. Early research suggests that injecting 200 mL of solution containing dong quai intravenously (by IV) for 20 days does not improve brain function in people who had a stroke due to a blocked blood flow to the brain.
