 【Predecessors release medicine】
 "Ben Cao Jing Shu" says: "The taste of Xuan Fu Hua is salty, which makes it moist and salty, and salty can soften hard masses; "Bie Lu" says that it is sweet, and sweet can relieve the middle; it is slightly warm, and warm can pass the qi, so it is mainly used to treat qi stagnation and fullness under the ribs; if the heart and spleen are damp, the disease will be palpitations, and the dampness will be eliminated and it will return to normal. It can remove water, remove cold and heat between the five internal organs, and eliminate phlegm in the chest, saliva like glue, phlegm and water in the heart and ribs, bladder retention, wind and dampness, dead muscles between the skin, open eyes, and benefit the large intestine. All of these have the functions of softening hard masses, cooling, moistening, eliminating phlegm and removing water. It is said that it can replenish the middle and lower qi because sweet can relieve the middle and salty can moisten the lower. It can circulate blood vessels and improve color, which means that the spleen will be healthy when the dampness is eliminated, and the spleen can flow, and the spleen wraps blood and regulates blood.
 "Compendium of Materia Medica" says: "Inula flower can dispel phlegm and expel water, and it is also a medicine that can help qi to flow downward. It is used to treat qi stagnation in the heart and lungs, fullness under the hypochondrium, phlegm in the chest, belching due to hard masses, or hidden fluid in the heart and spleen, fluid retention in the bladder, and water retention. This medicine is generally slightly salty to soften and disperse hard masses, and it is beneficial to move qi downward to move phlegm and water, and it is actually a medicine that can dispel and eliminate. "Compendium of Materia Medica" says that it can calm palpitations and replenish the middle qi. I think that phlegm blocks the pericardium and spleen network, which often makes people feel frightened. Inula flower can dispel phlegm and expel fluid. When phlegm and fluid are removed, the pericardium and network are clean and unobstructed, the five emotions are calmed, and palpitations are relieved. In addition, when fluid is eliminated, the spleen is healthy, and when swelling is healthy, the diet can be transported, and the middle qi is benefited and nourished. Tong Yufeng also said that if it is hot phlegm, it will cause irritability and fever; if it is damp phlegm, it will cause fatigue and weakness; if it is wind phlegm, it will cause paralysis and strange diseases; if it is cold phlegm, it will cause heart pain and epilepsy; if it is cold phlegm, it will cause bone paralysis and paralysis; if it is drink phlegm, it will cause flank pain and arm pain; if it is food phlegm, it will cause lumps and fullness. There are various symptoms, and using Inula flower, deficiency or excess, cold or heat, according to the symptoms, all of them will be effective.
 "Compendium of Materia Medica" says: Xuanfu flower can relieve qi stagnation, reduce phlegm, clear water channels, and reduce swelling. It is suitable for those with dampness and heat in the qi. However, its nature is to disperse, so it is not suitable for those with weak large intestine and qi deficiency and yang deficiency.
 "Ben Cao Zheng Yi" says: "The main treatment of Xuan Fu Hua should be to dispel wind and cold and dredge the meridians. "Bie Lu" says that it can treat wind and dampness, dead flesh between the skin, dredge blood vessels, and remove wind from the head and eyes. It is the most correct way to treat wind and cold cough and cold drink soaking the lungs. Some people say that Xuan Fu Hua can lower qi, and it is not suitable to use it early if the cold evil is in the lungs. They only know that the power of dispersing is enough to descend, but they don't know that its flying nature can rise. Moreover, "Ben Jing" clearly says that it is warm, and Kou Zong thinks it is pungent, so it can dispel cold evil and correct its special job. If it is used to open knots and drain water, lower qi and reduce adverse effects, it is all heavy and downward, which is not in line with its light and upward nature. According to "Ben Jing", Xuan Fu Hua is also called Jin Fei Cao. It is suspected that the ancients used its stems and leaves, but not necessarily its flowers. The functions of the flowers and leaves of plants are very different. Some are ascending and some are descending. Each has its own meaning. It is also due to their endowment and cannot be mixed. Moreover, the stem is heavy, while the flower is light. This is also the nature of physics. Moreover, the flower of Inula is particularly light and ascending. However, people nowadays always use its flowers, but not the stems and leaves. They use the heavy function to blame the light quality. I am afraid that this is not the true purpose of the ancients to distinguish the nature of things. Moreover, its flowers are specialized in warming and dispersing, and the power of dispersing is also strong. It is suitable for cold drinks, but not for hot phlegm. Shi Wan has said that if it is used incorrectly for yin deficiency, fatigue cough, wind-heat and dry cough, the cough will be worse. This is also because it is light and ascending. It is the opposite of the principle of descending qi. However, due to its light and agile nature, it flows without stagnation, and can naturally circulate qi and dissipate blockages. It is not specialized in ascending and dispersing. If the treatment is only to expel water and dampness, it seems more reasonable to use its stems and leaves as well. "Bielu" says that its roots are specifically used to treat rheumatism, and its meaning is clear.
