A condition in which the tissue that normally lines the uterus grows outside the uterus. In Classical Chinese medicine we find stagnation in the Qi of the liver which maintains the uterus. The stagnation is caused by either heat or wind (wind is a CM term that describes movement). The 5 phases of Chinese medicine are wood fire earth metal and water, fire and wood both have expansive qualities, they also consume healthy Qi. The heat (or wind) has penetrated the Qi of the uterus, this consumes normal ‘upright’ Qi and the ensuing deficiency stagnates the flow of Qi leading to endometriosis. Acupuncture is then applied, to first of all get the Liver Qi moving, this starts to cool down the heat. The underlined heat or wind must be dealt with also, usually it is dispersed from the body. The cause from a western sense is not entirely clear. Risk factors include having a family history of the condition, but also infection, emotions, or even medication might trigger it.
