conditions or getting wet and being exposed to cold during the menstrual period may produce cold dampness which impairs the Lower Jiao and stagnates in the uterus,thereby congealing the blood and obstructing the menstrual flow causing pain.
2.Liver Qi Stagnation
Cold dampness obstruction in the uterus,liver qi stagnation,impairment of the Chong and Ren meridians
Liver and kidney Yin deficiency,depletion of essence and deficiency of blood
Stasis of menstrual blood in the uterus

3.Liver and Kidney Yin Deficiency
A liver and kidney Yin deficiency,weak constitution or excessive sexual activity leads to liver and kidney Yin deficiency,depletion of essence,deficiency of blood,and insufficient blood supply in the Chong and Ren meridians.After menstruation,the sea of blood is totally depleted and is even less able to nourish the uterus,causing deficiency pain in the lower abdomen.
