Vocal cords are important organs for pronunciation. When the vocal cords move to the midline and the glottis close, air flows out of the lungs and impacts the vocal cords, which will make a sound. This sound is called pitch. Then, all kinds of sounds and sounds are made through the ringing of throat cavity, pharynx cavity, nasal cavity and chest cavity, as well as the movement of lips, teeth, tongue, soft palate and cheeks in coordination with the nervous system. Pronunciation, as opposed to breathing, is a random action. You can also act at will. The sound depends on the length of vocal cords, and tension has the power to exhale air. If the tension of vocal cords increases and becomes shorter and thinner, the vibration frequency will be higher, thus making a loud sound, otherwise it will form a bass. Due to various factors, incomplete opening and closing of vocal cords will cause hoarseness. The following methods are recommended for treatment. If the effect is not good, it is best to go to the local otolaryngology department to check the vocal cords.

The treatment of hoarseness is as follows: 1. Western medicine: amoxicillin tablets 0.5g, Banlangen granules 2 packets, three times a day for adults. 2. Traditional Chinese medicines: Schizonepeta tenuifolia 10g, Radix Rehmanniae 15g, Radix Ophiopogonis 15g, Bamboo Leaves 10g, and Radix Isatidis.
