Dong quai has been thought of as the female ginseng, since it is so widely used for female reproductive problems in China.
It’s also primarily known as a female tonic in the West as well. However, many people mistakenly believe that this is because it is hormonal (estrogenic) in nature.
Research suggests it isn’t. And it’s use for female troubles is not related to the Western idea of balancing hormones.
Instead, it’s primarily considered a blood (xue) tonic in TCM. It’s recommended to women primarily because of the blood loss that occurs every month during mensus. Dong quai helps to nourish and support the production of blood to maintain women’s health during childbearing years. It helps to build up deficient blood in women who are cold and pale.
Dong quai also helps to stimulate blood circulation, especially in the abdominal area. Ginger also does this and both have been used to ease female cramping and pain. The aromatic quality of dong quai also means it’s a qi tonic, giving it a warming quality. Pain is believed to be caused by stagnation of blood and energy (qi) in TCM so this is another quality that makes it helpful for female reproductive problems. - Steven Horne
