At first glance, many patients, and even doctors, may have great doubts that vocal cord lesions can be related to the spleen and lungs. This is because modern medicine, basically, starts from a localized approach to explain the causes of vocal cord nodules and polyps in chronic laryngitis. If we combine this with the understanding of Chinese medicine, it will be clear. We know that normal digestive function, i.e. normal spleen and stomach, as traditional medicine says, can provide sufficient material basis to produce sufficient lung qi, which can pluck the vocal cords, as if plucking the strong strings with strong hands, to produce a loud and powerful sound. If the digestive function is abnormal, for example, if the patient has a chronic loss of appetite and loose stools, which is a symptom of spleen deficiency, it will cause the earth to fail to produce gold and the lung qi to be deficient, thus making the vocal cords weak. After a long time, the vocal cords will be overworked, and the patient will not be able to speak long, as if he or she has to exert all his or her strength, or even be exhausted after speaking. This is the lung and spleen deficiency symptoms, and people often say that the evidence of deficient middle energy. If the patient usually likes to eat fat, sweet, spicy and other heavy foods, it will make the spleen and stomach phlegm and dampness inside, up in the throat, so that the throat is thick and heavy, the same conditions, need to spend more energy to drum the larynx vocal, as if the engine to drive all the joints, parts are not maintained car, need to consume more energy, the same will deplete the lung qi, resulting in throat lesions, so the traditional singers, are avoid fat, sweet thick-tasting products, diet on the lighter side. If the external wind-cold, wind-heat evil, the upper congestion in the throat, resulting in edema or congestion of the vocal cords, increased quality, at this time, such as forced to speak, will aggravate the vocal cords and lesions, and even lead to vocal cord nodules or polyps.
