Yu's friend, from your description, "When you look in the mirror, you can clearly see white sputum. When you go to ktv to sing more than three songs, there will be a faint bloody smell in your throat. Still can't cough up phlegm. Drinking warm water will be better, but in less than a minute, there will be phlegm again. " I think there is a foreign body in my throat. I always feel something in my throat. I can't swallow it or spit it out. From the perspective of traditional Chinese medicine, it belongs to the "plum nuclear gas" of traditional Chinese medicine, and phlegm and dampness block the lungs. Chinese medicine says that the spleen is the source of phlegm and the lung is the reservoir of phlegm. Treatment: strengthen spleen and clear lung, resolve phlegm and eliminate dampness. It is suggested to treat with traditional Chinese medicine.

Here, I'll give you a prescription for your own decoction. The prescription is: Pinellia ternata 15g, Magnolia officinalis 10g, Perilla frutescens 10g, Poria cocos 10g, ginger 8g, Fructus Trichosanthis 15g and Arisaema cum bile 10g.

You can go to a Chinese medicine shop to buy medicine according to this, which can save a lot of money. This is an oral dose of medicine. First, soak in cold water for 20 minutes. After the fire boils, fry it for 20 minutes and pour it out. Then add cold water, and after the fire boils, fry for 20 minutes with low fire. The two kinds of decoction are mixed together and divided into two parts, one in the morning and one in the evening. Be careful not to use aluminum pot and wok. It's better to fry in casserole. Ensure obvious improvement within 3 doses, and then drink a few more doses according to the improvement. When you feel better, you'd better take three more doses to remove the root cause. If it is not convenient for you to decoct medicine, you can ask them to decoct medicine for you when you go to the drugstore. They will burn a bag according to the amount used each time, but you may have to pay a certain decocting fee.

Suggestion: don't smoke, don't be greasy when eating, because being too greasy is easy to hurt the spleen and produce phlegm, which is not conducive to the improvement of the condition. And pay attention to keep warm to prevent colds, so as not to aggravate the condition.
