The cause of hoarseness should be clarified and appropriate treatment measures should be taken according to the cause. Drinking water can only relieve the discomfort, but has no curative effect. If you have a hoarse voice, you may have laryngitis or vocal cord infection. In this case, besides abstaining from speaking and drinking water to keep your throat moist, you can also apply Chinese medicine to clear your throat and benefit your voice. If the hoarseness is caused by excessive use of the voice, you can drink water with fat sea, honeysuckle and chrysanthemum, which have the effect of moistening the lungs, clearing heat and detoxifying and lowering liver fire; you can also drink honey water to lubricate the throat, reduce edema and help improve hoarseness. If the hoarseness is caused by inflammation, you can take drugs to clear heat and remove fire and antibiotics, along with hormonal drugs for nebulized inhalation treatment. If the symptoms do not improve significantly with the application of the above methods, you should seek medical attention as soon as possible to rule out hoarseness caused by abnormalities in physiological structures, tumors, etc. through examination by laryngoscopy or electronic laryngoscopy. Patients are advised to eat more green leafy vegetables, such as bok choy and cabbage, etc. They can also eat more fruits with laxative effect, such as kiwi and grapefruit, to relieve the dryness of the throat and provide rich vitamins to promote the secretion of mucous membrane and glands in the throat. Patients are advised to eat more warm and cool liquid food, and try to avoid overly hot and hot, greasy and spicy stimulating food.
