Coughing up foul-smelling dry crusts is a common symptom of chronic pharyngitis, which, when prolonged, can also lead to atrophy of the pharyngeal glands and mucous membranes. The pharyngeal mucosa and submucosal tissues become thin, blood vessels and glands are reduced, and the pharynx is dry, wrinkled or shiny. So what is its pathogenesis? The pathogenesis of the disease is complex, with “qi” as the key, the pathogenesis of the internal organs is closely related to liver, gallbladder, spleen, stomach and heart, and the pathogenesis of qi, blood and fluid is closely related to qi stagnation, phlegm coagulation and blood stasis. Among them, liver depression and qi stagnation, phlegm and qi intertwined are common. 1, liver depression and qi stagnation: depression of emotion and will, loss of wood regulation, liver depression and qi stagnation, choking in the throat. The “Spring of All Sicknesses” Volume 5: “Plum nucleus as a disease, most of the seven emotions of the gas stagnation. Or because of food and drink, offended by anger, then become this disease. Only women suffer most from this.” 2, phlegm and gas mutual knot: liver depression spleen, phlegm and turbid internal growth, or spleen deficiency phlegm, and then due to the seven emotions of the gas knot, phlegm and gas interfere with the throat, the development of this disease. Such as Sui – Chao Yuan Fang “the source of diseases,” XXXIX pointed out that “pharynx like a sizzling meat, this is the chest and diaphragm phlegm knot, and the gas fight, reverse up the throat between the knot, like a sizzling meat of the slices also.” Laryngitis is a very headache disease, hot and cold, too cold and too hot weather, so laryngitis patients can not say. The general treatment is also to treat the symptoms but not the root cause, so laryngitis patients headache. This disease can not be rushed, Chinese medicine is concerned about conditioning, in fact, as long as the right diet can ease the symptoms. The actual fact is that you can find a lot of people who are not able to get a good deal on their own. The most important thing is to find the most appropriate solution and prevention principle, regardless of the cause of chronic pharyngitis, prevention is better than cure, for healthy people and patients who have had chronic pharyngitis, is the most important response principle.
