There is an advertising slogan: “Drink XXX when you have a fire”, which should be a household name. Drinking herbal tea, which has a strong herbal tea culture in Guangdong, is more than natural, did not drink herbal tea a said out, people do not believe that you are Cantonese, so most people do not think there is anything wrong with drinking herbal tea. I am a Hakka, I remember when I was young, as long as the fire, my father always to boil some herbal tea to me to drink. Now, when I go back home, I still look at my friends and relatives who are still drinking herbal tea at every turn, even if they are a few dozen years old, including my parents. If I hadn’t studied Chinese medicine, and hadn’t clinically seen too many patients who seemed to be on fire, the clearer the heavier, I would probably still be like them, even though the whole body is very cold in winter, frequent night urination, cold extremities hard to warm, women with dysmenorrhea, Yang deficiency is obvious but still continue to drink herbal tea! I now know that many people’s illnesses come from excessive herbal tea drinking! Because there is no identification of whether it is a real fire or a false fire! Chinese medicine is not without side effects, remember, it is important to identify the body type! You can’t just drink herbal tea for deficiency fire! Such as acne, laryngitis, constipation, all may be false fire! Once, when I was in class, I asked my students, “Why are we southerners shorter?” I jokingly told them, “Because they drink too much herbal tea! How can people grow taller when their yang energy has been dissipated?” Zhu Danxi said that children’s constitution is “Yang is always in excess and Yin is always in short supply”, so they are prone to fire. And sufficient yang energy is the key to our healthy growth. Fire on the drink herbal tea, now look back, feel like drinking poison. Because I grew up drinking too much, so now the body is thin. Of course, I think that the southern people are more thin and small, and located in the south, the natural Yang heat more floating outside, difficult to hide related to the popularity of the people should be, so people located in the south, more also easy to Yang floating over, easy to swell the throat, Yang hidden bad, the spleen and stomach in the earth more weak, the kidney often deficient. Modern people on fire, deficiency fire is more common, the real fire is less common, why? First, long-term consumption of cold, cold food, such as cold drinks, herbal tea, frozen beer sprinkles, etc.. The second is to sleep late and stay up late, depleting fluid, Yang does not hide then floating over the table, Yang collection powerless, long is the deficiency of kidney Yang. Third, the summer air conditioner is accompanied by long, cold drinks, cold evil is very easy to hurt the spleen and kidney Yang. Fourth, sleeping lazily and exercising less, resulting in weakness of Yang Qi. Having said all this, I hope that with my own efforts, I can alert the people around me, and I hope that my students can better understand deficiency fire, and in the future, in the clinic, they can remember what Mr. Lai has said, and make better treatment plans for patients, and remind the people around them to stay away from herbal tea! I hope my friends will have a healthier lifestyle and a healthier body!
