For a long time, most people think that Chinese medicine is non-toxic, and this knowledge has spread widely and left a deep impression on people. According to the author's experience in clinical application of traditional Chinese medicine, it can be said with certainty that there are very few traditional Chinese medicines with obvious toxicity, such as arsenic and nux vomica. And some relatively less toxic Chinese medicines, such as Pinellia ternata and almond. Of course, most traditional Chinese medicines are not toxic, such as ginseng, astragalus, lily, Ophiopogon japonicus and velvet antler. Second-class Chinese medicine, also known as Chinese medicine; Three kinds of inferior drugs, also known as drugs. People usually think that the top grade is non-toxic Chinese medicine, while the middle grade and the bottom grade are toxic Chinese medicine. Non-toxic Chinese medicine is used for health care and toxic Chinese medicine is used for treatment, but it still seems to have defects. Toxic Chinese medicine: As mentioned earlier, toxic Chinese medicine has a significant therapeutic effect, so how to use it correctly? First, when using toxic traditional Chinese medicine, we must strictly follow the spirit of syndrome differentiation and treatment of traditional Chinese medicine, so as to achieve accurate syndrome differentiation and rational drug use. Only in this way can we avoid poisoning symptoms. If you fail to get to the point of the lesion and make use of it, it will not only be beneficial to the treatment, but also have toxic and side effects. Second, when using toxic traditional Chinese medicine, we must identify the lesions and determine the dosage according to law. If the drug dosage can be reasonably distributed, toxic Chinese medicine will not appear poisoning symptoms. For example, in the treatment of acute nephritis, if it is clear that the pathological mechanism is superficial deficiency and fengshui syndrome, then the dosage of about 3g (referring to adults) can achieve obvious therapeutic effect. If the dose is more than 10g or more than 15g, it will not only have no therapeutic effect, but also further damage renal function. Moreover, from the frequent reports of Chinese medicine poisoning, firstly, syndrome differentiation and treatment failed to clarify the pathogenesis of the disease, and toxic Chinese medicine was used to treat the disease at will; Second, the dose distribution of drugs is improper; Third, I mistakenly think that Chinese medicine is non-toxic and does not discriminate abuse. Any of the three categories can cause poisoning symptoms. Therefore, it can be seen that the use of toxic Chinese medicine must be objective, correct and reasonable, and must not be taken at will, and the use of toxic Chinese medicine must be based on the symptoms of the disease, which can not only improve the clinical treatment effect. It can also avoid poisoning symptoms caused by blind application of toxic traditional Chinese medicine. Non-toxic Chinese medicine: toxic Chinese medicine plays a very important role in treating diseases, and some non-toxic Chinese medicine also plays a very important role in treating diseases. For example, rhubarb, although non-toxic, can play an important role in treating heat stagnation syndrome; For another example, although Rhizoma Coptidis is non-toxic, it plays an important role in treating heart-heat syndrome such as irritability and impatience, while some non-toxic Chinese medicines are not obvious in treating diseases, such as Chinese dates, yams and other qi-invigorating drugs, but the therapeutic effect is not obvious; Another example is mint and chrysanthemum, which are pungent and cool drugs for relieving exterior syndrome, and the effect of treating exterior syndrome of wind-heat is relatively weak. It is difficult to achieve the expected therapeutic effect by simply using mint and chrysanthemum. At the same time, it should be clearly pointed out that non-toxic traditional Chinese medicine with obvious curative effect cannot be taken for a long time, and traditional Chinese medicine with no obvious curative effect, such as jujube and yam, cannot be taken for a long time. If taken for a long time, it will cause qi stagnation in the spleen and stomach. I have abdominal distension and don't want to eat. Another example is mint and chrysanthemum, although they have no obvious therapeutic effect, they cannot be used for a long time. If used for a long time, it will be cold, inhibit spleen and stomach yang, cause abdominal distension and poor diet. With the deepening of people's understanding of Chinese medicine, we should comprehensively and objectively understand toxic Chinese medicine and non-toxic Chinese medicine. Only in this way can we use toxic or non-toxic Chinese medicine correctly. We should also know that toxic Chinese medicine is medicine and non-toxic Chinese medicine is medicine. Toxic Chinese medicine can cure diseases, and non-toxic Chinese medicine can also cure diseases. Toxic traditional Chinese medicine, if used improperly, will cause drug poisoning and even endanger life. However, if the non-toxic traditional Chinese medicine is used improperly, it will cause adverse drug reactions and aggravate the condition. We should fully understand this method. (Excerpt from the prescription interviewed by Wang) The medicine you used is slightly toxic, but the problem is not serious. The key is to prove it to you. If the medicine is wrong, tonic can also kill people.
