Left vocal cord paralysis can be treated with Traditional Chinese Medicine (TCM), but the exact effect needs to be decided according to the patient’s condition. Vocal cord paralysis is a vocal cord movement disorder caused by damage to the motor nerves of the laryngeal muscles. It is mostly seen in people above middle age. Laryngeal recurrent nerve palsy is the most common. After active treatment of the primary disease, the general symptoms can be improved. For vocal cord paralysis, Chinese medicine believes that it is generally caused by heat in the lung meridian, phlegm and dampness, and blood stasis, etc. Clinically, it is common to clear heat and moisten the lungs (to remove heat to nourish the lungs), eliminate phlegm and dampness, and activate blood circulation and remove blood stasis (to promote the operation of the blood and remove blood stasis in the body) and other treatment principles, and commonly used in clinics to treat it by adding or subtracting formulae such as Sasan and Maidong Soup, Ercheng Soup and Huiyouyuyuyuyu Soup. Patients with vocal cord paralysis should avoid excessive vocalization in daily life, protect the vocal cords, and exercise appropriately to enhance immunity. If medication is needed, it should be diagnosed by a doctor and follow the doctor’s instructions for standardized treatment.
