According to TCM, Plum nucleus qi (similar to pharyngeal allodynia) is a condition mainly characterized by the sensation of foreign body obstruction in the pharynx, which is manifested by coughing and swallowing. It can be treated with medicines such as Semixia Houpu Tang. Plum nucleus qi is mostly related to the seven emotions and unfavorable qi. Generally, for those with a short course of the disease, liver depression and qi stagnation (poor qi and blood transportation of the liver and depression) are the main causes, and prolonged or recurring episodes are due to liver-spleen disharmony (the liver and the spleen failing to coordinate their work) and phlegm-qi interlacing (phlegm and qi in the body accompanying the poor qi). The main manifestation of plum nucleus qi is a sense of foreign body obstruction in the pharynx, the shape of which is like a plum nucleus or sliced meat obstruction, which does not come out of the clucking, and does not come down in the swallowing, but does not hinder the eating and breathing, and the symptom will be aggravated when the mood is not comfortable (emotionally unruffled), and when the mood is depressed. When diagnosed as suffering from prune nucleus qi, one should consult a doctor in time and use medicines under the guidance of a physician, such as Half-summer and Thick-skin Soup. This medicine is composed of the medicines Hanxia, Houpu and Poria, which have the efficacy of promoting qi circulation and dispersing lumps (smoothing the body’s qi and dissolving the lumps), and subduing rebelliousness and resolving phlegm (correcting rebellious qi and removing phlegm and evil spirits from the body). It is used as the main treatment for plum nucleus qi. The adverse reactions and contraindications of this drug are not clear, and it is recommended to use the drug under medical supervision. If the patient has the above symptoms, it is recommended to consult a doctor promptly and follow the doctor’s instructions.
