1. Concept of Qi Stagnation Qi stagnation: refers to a pathological state where the flow of Qi is obstructed, leading to stagnation and blockage.
2. Causes of Qi Stagnation: 1. Qi stagnation is primarily caused by emotional distress, or by the obstruction of phlegm, dampness, food accumulation, heat, and blood stasis, which affects the flow of Qi;
2. It can also result from dysfunction of the internal organs, such as the liver failing to disperse Qi or the large intestine failing to transport, leading to local or systemic Qi stagnation, which can cause dysfunction in certain organs and meridians.
3. Qi stagnation generally belongs to the category of excess pathogenic factors, but it can also occur due to Qi deficiency leading to insufficient propulsion. 3. Pathological Manifestations of Qi Stagnation: The pathological manifestations of Qi stagnation can be observed in several aspects:1. Qi stagnation in a specific meridian or local area can lead to corresponding symptoms of fullness and pain in that area.
2. Qi stagnation can impede blood circulation and the distribution of body fluids, thus severe Qi stagnation can lead to blood stasis and fluid retention, resulting in pathological products such as blood stasis and phlegm-dampness.
