The more expensive something is, the better the quality, the public has this understanding, generally speaking, for the same product can be judged in this way, such as Ganoderma, artificially grown and wild price is huge difference, the quality will also have a corresponding difference; but for different products can not be compared, for example, in the famine years, for a hungry person, is a bun more valuable, or a piece of gold is more valuable? The same is true of medicine for treating illnesses. In both Chinese and Western medicine, after looking (seeing), smelling (touching), asking (asking), and cutting (listening), combined with relevant laboratory tests, the doctor will have a preliminary diagnosis, and on this basis, the prescription of medicine is based on the patient’s specific situation, and we call it “individualized” treatment, for example, when the liver and gallbladder damp-heat For example, if there is damp-heat in the liver and gallbladder, we should use Gentian Diarrhea Liver Soup; if there is stagnation of liver qi, we should use Chai Hu Dredging Liver San; for wind-cold colds, we should use Ma Huang Tang; for wind-heat colds, we should use Yin Qiao San, etc. In the prescription, the doctor will also add or subtract medicine according to the patient’s physical condition, the season of illness, and the severity of the illness, in order to achieve better treatment results. Some patients feel that they are usually fatigued and ask the doctor to add Astragalus and Radix Codonopsis, and some patients add Astragalus and Radix Codonopsis on their own, thinking that this will improve the immunity of the body and facilitate the recovery of the disease. In fact, adding other drugs to the doctor’s rigorous prescription may interfere with the efficacy or even be harmful. For example, with the accelerated pace of life and increased work pressure, many white-collar workers have liver qi stagnation, manifested as poor temper, easy to get angry, chest tightness, discomfort in the liver area and other symptoms, at this time, should be mainly to relieve, many people will also take some tonic drugs on their own, at this time is tantamount to pouring oil on the fire, liver qi stagnation even more, qi depression into fire, symptoms aggravated. In the public mind has always had a plot, see ginseng, astragalus, wolfberry will be happy, see rhubarb, Huang Lian, etc. will be bitter, this is a “like tonic aversion to diarrhea” psychology at work, people hope to enhance immunity, health and longevity, and the overwhelming publicity is “tonic medicine This is a “tonic aversion” mentality. Chinese medicine is a rigorous medicine, with its theoretical basis, the essence of Chinese medicine diagnosis is the imbalance between the “yin” and “yang” of the body, the fundamental treatment is to balance yin and yang, deficiency is tonic, the real is diarrhea, supplement deficiency diarrhea real, to achieve the state of yin and Yang secret. Therefore, the medicine is not expensive, the right evidence is good.
