Hovenia Citrus and Allium cotyledonii Tang is usually used to treat coronary heart disease with chest yang deficiency and phlegm-qi interlacing (phlegm in the body accompanied by qi dysfunction), but it is not usually used to treat other types of coronary heart disease, so there is no such thing as Hovenia Citrus and Allium cotyledonii Tang for all coronary heart disease. Hovenia Citrus and Allium Scallion and Gui Zhi Tang has the effects of promoting yang and dispersing knots (warming yang qi and dissipating stagnation), expelling phlegm and lowering qi. It is used to treat chest paralysis (tightness and pain in the chest) in which chest yang is not vibrant and phlegm and qi are intertwined. Symptoms include chest fullness (chest distension and discomfort) and pain, or even chest pain across the back, wheezing, coughing and spitting, and shortness of breath. This formula is often used in treating angina pectoris of coronary heart disease, intercostal neuralgia, non-suppurative costochondritis, etc., which is characterized by chest yang dysplasia and phlegm-qi interlocks. It is recommended that patients use the medicine under the guidance of traditional Chinese medicine practitioners, and should not blindly use the medicine on their own, so as not to make mistakes.
