Based on the"pivot movement"theory of distinguished physician Huang Yuanyu in the Qing Dynasty,it is believed that the core mechanism of abdominal flatulence disease is the unfavorable operation of the central axis pivot,and the ascent and descent disorder of qi movement in the central earth.The pathogenesis of abdominal flatulence disease was explained from the perspectives of mistakenly dropping the damage to yang,keeping the lung qi from falling,and declining central qi deficiency.The main concept of clinical practice was to promote the movement of the middle earth,promote the movement of the spleen and stomach,and restore position of yin and yang and clearing and turbidity.Examples were given of the five commonly used TCM prescriptions,including Xiaqi Decoction,Banxia Xiexin Decoction,Gancao Xiexin Decoction,Shengjiang Xiexin Decoction and Xuanfu Daizhe Decoction,to explain the treatment approach guided by the theory of"pivot movement",in order to provide reference for clinical diagnosis and treatment.
