In Guangzhou, most doctors will say that it is wind-heat cold or wind-heat with dampness, and most of the prescriptions used are Yin Qiao San, Sang Ju Drink, Sang Xing Tang, San Ren Tang and so on, few doctors say it is wind-cold cold, so hemp Gui and so on are rarely used. Why is this? I think this view is biased, in clinical work, I found that the vast majority of colds are caused by wind and cold, in layman’s terms, you do not get cold or wind, how can you catch a cold, even in the hot summer, is caused by sweating when the wind or greedy cold. Imagine, when people are in sauna, the temperature is very high, people usually do not catch a cold, but when they come out of the sauna and accidentally blow the wind or catch a cold, they will easily catch a cold. At this point, some patients ask why the doctors all say I have a wind-heat cold and we also feel a sore throat as if we have a fire. I think so. Generally speaking, Cantonese people belong to yin deficiency or damp-heat constitution, and wind-cold easily enters into heat. Therefore, after wind-cold cold, heat will be turned into heat very quickly, and usually heat images such as sore throat and yellow sputum will appear in a few hours to a few days, and physical examination also reveals that the throat is congested with blood and bright blood, and even the tonsils are septic and swollen. However, at first, the patient has fear of cold or generalized aches and pains, little sweating or runny nose, which is actually caused by wind and cold. Therefore, I would like to remind the majority of sufferers, at the beginning of the cold, the use of ginger, onion white, brown sugar water sweating, is very good, the so-called in the Wei sweat can also be, is this reason, if not relieved, there is a sore throat, yellow sputum and other symptoms, and then use our commonly used clearing fever anti-inflammatory Ning, anti-virus or Chai Yin oral liquid will achieve certain results. Premature use of cold medicines will lead to internal trapping of wind and cold, which can lead to sore throat and cough that does not heal. We hope to draw the attention of our patients to the above points.
