Yin & Yang Menstrual imbalances
The reproductive system is regulated by the hormonal and circulatory system, the cycle of these internal rhythms are affected by physical, emotional, nutritional factors, stress through work and also relationship stress.
From the viewpoint of TCM the Livers function of storing blood pays an importantly role in the well being of the female reproductive system, also exposure to cold (Yin ), excess cold food, weakness of Qi and blood are the major causes of menstrual disharmonies.

The reproductive system is regarded as being Yang  in nature, so excess Yang influences is damaging to the system, i.e. Eating excess Yang  food (meat, eggs, salt), taking too hot baths, (a daikon bath is good for strengthening the reproductive system).
