Legend of Chinese Herbs

Dang Gui (Radix Angelica Sinensis) 

Dang means “should”, Gui means “return”. The herb of Dang Gui has a story. “In the ancient time, a lady failed to get pregnant for years because of her menstrual problems. Her husband was so angry and left home. The lady was very sad and went to see a Doctor. The doctor gave her the herb Gang gui. She started taking it everyday. After a while, her menstruation got back to normal. She was told by the doctor she was ready to get pregnant. The smart lady wanted her husband to come back. She did not know how to write, so she asked somebody to send a piece of Dang gui to her husband as a message for her. The husband saw the herb Dang Gui (Should return). He understood it was the time for him to go home. They had children soon after he went home. The whole family were living together happily in the rest of life.” In Chinese culture, Dang Gui is not only a precious herb, but also a love token between lovers. 
This herb in shape can be classified as two parts, the body and the tail (the sharp part). This herb can both nourish blood (the body part) and move blood (the sharp part). Since menstrual flow depends on gathering of blood and movement of blood to the uterus, disorders of the menstruation, such as irregular menstruation, amenorrhea and dysmenorrhea, etc. could be caused by either blood deficiency or stagnation of blood, or both. That is why Dang Gui serves as a very important herb in treating menstrual disorders. In terms of modern research, Dang Gui contains some female hormones that why it is so important for women’s problems.  
 
Dang Gui can move blood, but it is also a warm herb. So it is a good herb at relieving pain caused by blood deficiency and stasis. That is why it is also used to treat abdominal pain due to deficiency cold, pain due to blood stasis, traumatic injury and numbness of limbs in Bi syndrome.
