Abstract: Endometrial polyp is a common and frequently occurring disease. Based on the theory of "yang transforms into qi, while yin constitutes form" in The Yellow Emperor's Inner Classic, Professor Xia Guicheng, a master of traditional Chinese medicine, believes that endometrial polyp is a disease of asthenia in origin and asthenia in superficiality, and its disease mechanism is heart-kidney yang deficiency, abnormal qi transformation, and static blood obstructing the uterus. Thus, the treatment is based on the method of warming yang and transforming qi, combined with the method of nourishing kidney to regulate menstruation. In addition, the formula of warming yang and transforming qi is created. All these treatment methods are applied in the pre-menstruum of yang exuberance using methods of warming kidney to assist yang along with transforming qi and breaking concretions. Having the "six yang" in place, the aim is to turn extreme yang into yin, restore uterine function, promote the elimination of endometrial stagnation and fluid during menstruation, as well as reduce the recurrence of endometrial polyps.
