Definition:Liver Qi Stagnation Syndrome: A condition characterized by emotional distress, failure of the liver to regulate, and stagnation of Qi. Common clinical symptoms include chest and hypochondriac fullness, breast tenderness, lower abdominal pain, and menstrual irregularities in women.
Spleen Qi Stagnation Syndrome: A condition resulting from food accumulation, or invasion of cold-damp or damp-heat pathogens, obstructing the middle jiao, along with emotional distress leading to liver Qi invading the spleen, resulting in stagnation of spleen Qi. Common clinical symptoms include abdominal fullness, vomiting, and poor appetite.
Etiology:Liver Qi Stagnation Syndrome: Emotional repression, prolonged sadness, and excessive worry can lead to the liver’s failure to regulate and disperse Qi, resulting in stagnation. Sudden emotional stimuli, such as fear or panic, can also cause Qi stagnation. Liver diseases are often related to emotional factors, as the liver governs the smooth flow of Qi, and emotional distress can significantly impact the liver’s ability to regulate Qi, leading to various pathological changes. Spleen Qi Stagnation Syndrome: Overeating, undigested food, and emotional distress can obstruct the spleen’s function. Excessive consumption of spicy and greasy foods can generate damp-heat, or external cold-damp can obstruct the spleen, leading to Qi stagnation. If emotional distress persists, it can further hinder the liver’s ability to regulate, resulting in Qi stagnation.Pathogenesis:Liver Qi Stagnation Syndrome: The liver is a solid organ that prefers smoothness and flexibility, governing emotional regulation and storing and regulating blood volume, which aids in the digestion and absorption of the spleen and stomach. If liver Qi is stagnant, it can obstruct the spleen and stomach, leading to abdominal pain. If the stomach fails to descend, it can cause vomiting. If liver Qi invades the spleen, it can lead to diarrhea, abdominal distension, and loss of appetite. If liver Qi is not smooth, it can ascend and cause headaches. Emotional factors such as anger or fear can lead to Qi stagnation, resulting in symptoms like sudden fainting or cold extremities. If Qi stagnation is unresolved, it can lead to Qi reversal and hernias.
Liver Qi stagnation, if unresolved over time, can transform into liver fire, leading to symptoms of liver fire rising, which can deplete Yin blood, resulting in liver blood deficiency and liver Yin deficiency. Insufficient liver Yin can lead to excessive Yang, causing internal wind. If liver blood and Yin are deficient, it can also lead to blood deficiency generating wind and Yin deficiency causing wind. In summary, liver Qi stagnation can lead to liver blood deficiency and liver Yin deficiency, and it serves as a pathological basis for liver Yang rising, liver fire rising, and internal wind movement. Liver diseases often affect other organs, such as liver Qi invading the spleen; liver fire attacking the lungs; liver Yin deficiency affecting kidney essence, leading to liver and kidney Yin deficiency; and liver blood deficiency affecting the heart, leading to heart and liver blood deficiency, with liver Qi stagnation commonly affecting other organs.
Spleen Qi Stagnation Syndrome: The spleen is a damp earth organ that prefers dryness and dislikes dampness. External cold-damp and internal damp-heat can easily obstruct the middle jiao, leading to spleen dysfunction and resulting in Qi stagnation. Additionally, food accumulation and fluid retention can obstruct the middle jiao, causing spleen Qi stagnation and poor Qi flow. Spleen Qi stagnation can also lead to the formation of pathological products such as phlegm, food accumulation, and dampness. The spleen governs transformation and transportation; if spleen Qi is obstructed, it cannot transform food into essence, leading to phlegm and dampness accumulation. “Dampness can harm the spleen; if the spleen is deficient, numerous diseases arise” (from “Famous Physician’s Cases”). If liver Qi stagnates and invades the spleen, it can lead to abdominal distension and fullness. Liver Qi stagnation often affects the spleen’s function, as liver wood overcomes earth; if spleen Qi is obstructed, it can also harm the liver, leading to liver Qi stagnation.Key Differentiation Points:Liver Qi Stagnation Syndrome: Symptoms include emotional depression, irritability, chest and hypochondriac fullness, breast tenderness, lower abdominal pain, and pain that is not fixed. Symptoms may include chest tightness, belching, sighing, or discomfort in the throat, with a sensation of obstruction that does not interfere with eating, or menstrual pain and irregularities in women, potentially leading to amenorrhea. The tongue is pale with a white coating, and the pulse is wiry. Clinical features include emotional changes, and symptoms occurring in the liver meridian areas (chest, hypochondria, lower abdomen), along with menstrual irregularities in women. Spleen Qi Stagnation Syndrome: Symptoms include abdominal fullness, poor appetite, vomiting, belching, constipation, or sticky stools, with abdominal pain during defecation, a greasy tongue coating, and a wiry or slippery pulse. Clinical features include abdominal fullness, vomiting, poor appetite, and a greasy tongue coating.Analysis of Differentiation:Liver Qi Stagnation Syndrome and Spleen Qi Stagnation Syndrome are both pathological manifestations of Qi stagnation. They share common symptoms such as abdominal fullness, pain, belching, and a wiry pulse. However, due to the different affected organs, clinical manifestations vary. Liver Qi stagnation is caused by emotional distress, leading to Qi stagnation and dysfunction in Qi movement. Smooth Qi flow is essential for circulation within the organs and outward to the skin; any stagnation disrupts this flow. If Qi stagnates in the liver meridian, it can cause fullness and pain in the chest, hypochondria, and lower abdomen, with pain being variable. If liver Qi invades the stomach, it can cause stomach Qi to rebel, leading to belching. The liver prefers smoothness and flexibility; if liver Qi stagnates, it can lead to emotional depression and irritability. Emotional distress can lead to liver Qi stagnation, which often manifests as depression. Sighing can help relieve Qi stagnation. Liver Qi stagnation can generate phlegm, which can obstruct the throat, leading to a sensation of a plum pit. If Qi stagnates and blood stasis occurs, it can lead to abdominal masses. Blood stasis can disrupt the Chong and Ren channels, leading to menstrual pain, amenorrhea, and irregular menstruation. A pale tongue with a white coating and a wiry pulse indicates liver stagnation.
Spleen Qi Stagnation Syndrome is often caused by tangible pathogenic factors (food accumulation, dampness, phlegm) and intangible Qi stagnation, obstructing the middle jiao, leading to spleen dysfunction and impaired digestive absorption. For example, water-damp, phlegm, and food accumulation can obstruct the middle jiao, preventing the transformation and transportation of food, exacerbating the accumulation of pathological products, leading to abdominal fullness and pain. The “Discussion on Pathogenesis” provides a detailed explanation of abdominal pain due to accumulation: “Abdominal pain can be caused by three factors: cold, Qi stagnation, and food accumulation. The abdomen is the most Yin area, where the spleen, stomach, large intestine, and small intestine reside. The stomach governs receiving, while the spleen governs movement. The small intestine digests food, and the large intestine transforms waste. If one consumes excessive cold food or has excessive worry, it can obstruct the movement of Qi, leading to blockage in the three jiao and resulting in abdominal pain…” The spleen and stomach are interrelated; if Qi stagnates in the spleen, the stomach cannot function properly, leading to poor appetite, vomiting, and belching. If spleen Qi stagnates, it can lead to constipation due to the inability to transport waste. Therefore, it is believed that constipation is due to “Qi stagnation preventing movement.” If water-damp, phlegm, or food accumulation stagnates in the middle jiao, it can lead to sticky stools. Although both liver Qi stagnation and spleen Qi stagnation present with abdominal pain, the former is due to liver Qi not flowing smoothly, often accompanied by symptoms in the chest, hypochondria, and lower abdomen, while the latter is primarily abdominal symptoms due to obstruction in the middle jiao. Although both conditions may involve belching, liver Qi stagnation does not typically present with severe digestive dysfunction, while spleen Qi stagnation, due to the interrelationship between the spleen and stomach, presents with more pronounced digestive dysfunction, including nausea, vomiting, and constipation. Emotional factors significantly affect liver Qi stagnation, with symptoms improving with positive emotions and worsening with anger, while spleen Qi stagnation often worsens due to food accumulation and dampness. In terms of pathogenesis, liver Qi stagnation primarily involves dysfunction of the liver’s ability to regulate Qi, leading to Qi stagnation and potential blood stasis, while spleen Qi stagnation is characterized by the spleen being obstructed by pathogens, leading to impaired function. Both conditions are excess syndromes caused by Qi stagnation, and both can exhibit symptoms of digestive dysfunction, but liver Qi stagnation is a pathological consequence of liver stagnation affecting the spleen, while spleen Qi stagnation is a manifestation of the spleen being obstructed by pathogens. Liver Qi stagnation primarily affects the liver, while spleen Qi stagnation primarily affects the spleen and stomach. In terms of etiology, liver Qi stagnation is often triggered by emotional distress, while spleen Qi stagnation is often due to dietary indiscretion, overeating, or the accumulation of pathogenic factors. For treatment, liver Qi stagnation is typically addressed by soothing the liver and regulating Qi, often using Chai Hu Shu Gan San (Bupleurum Powder to Spread the Liver). Spleen Qi stagnation is treated by resolving stagnation and strengthening the spleen, often using Zhi Shi Dao Zhi Wan (Bitter Orange Pill to Guide Out Stagnation). Thus, “The soil must be cleared of stagnation; stagnation of the soil refers to spleen stagnation, and clearing refers to removing it… For abdominal obstruction and fullness, use Zhi Shi Dao Zhi Wan, Mu Xiang Bing Lang Wan, or Cheng Qi Tang to clear it internally. If food injures the spleen, leading to fullness and phlegm accumulation, use Ju Ban Zhi Shu Wan; if emotional distress leads to stagnation and poor appetite, use Mu Xiang Hua Zhi Tang or Xiao Pi Wan to resolve it, which also refers to clearing it.”
