The key to solve "traditional Chinese medicine" is to standardize planting

Replay: according to the recently released investigation report on pesticide pollution of traditional Chinese medicine, as many as 48 samples of 65 traditional Chinese medicine samples from 9 famous brands contain pesticide residues, and the situation of mixed pesticide residues is quite serious Among them, more than three kinds of pesticide residues were detected in 32 samples, and more than 20 kinds of pesticide residues were detected in 9 samples Question: why do Chinese herbal medicines contain pesticide residues? What harm will it cause? How to avoid pesticide contained in medicinal materials to the greatest extent? Answer: "it is harmful to take Chinese herbal medicines containing pesticide residues for a long time This phenomenon is probably related to the use of pesticides in the process of large-scale planting of traditional Chinese medicine " Qi Xianghua, chief physician of Neurology Department of Affiliated Hospital of Shandong University of traditional Chinese medicine, said about the test report issued by environmental protection organizations He believes that, unlike most of the traditional Chinese Medicine collected in the field in the past, the current traditional Chinese medicine is generally produced in groups, "a considerable number of drugs are planted in large areas" Just like cattle in the pasture are prone to diseases after centralized cultivation, Chinese herbal medicines are also prone to diseases and insect pests after centralized cultivation "If there are diseases and insect pests, it means that production is reduced, and pesticides must be used." Qi Xianghua also told reporters that the cultivation of traditional Chinese medicine has become less natural now, and diseases and insect pests are more likely to infect each other after large-scale cultivation "Just like crops, there is no one who does not use chemical fertilizers and pesticides It's just that the toxicity of the pesticides we use is high and low, but we can use them all " The best source of traditional Chinese medicine is from natural herbs However, Qi Xianghua said that natural herbs cannot be said to be absent, but the output is too low and the cost is too high "How much can a druggist collect from the mountain?" In addition, there is a lack of natural drug sources, which tends to be extinct after years of collection So, how to solve the problem of excessive agricultural residues in traditional Chinese medicine? Qi Xianghua believes that this is related to the cultivation and management of traditional Chinese medicine At present, it is urgent to regulate the cultivation of traditional Chinese medicine, "either purely natural or standardized production How to apply fertilizer and how to apply medicine for each kind of medicine must be refined like the foreign vegetable management " In addition, the state should strengthen the supervision of inferior Chinese medicinal materials and fake and inferior products, and severely punish the illegal acts of enterprises Yang Hongjun, a researcher at the Institute of traditional Chinese medicine, Chinese Academy of Sciences, stressed to reporters that the standardization of traditional Chinese medicine should also be strengthened He said that the standard improvement of traditional Chinese medicine is a gradual development process, and the standards of each edition of Pharmacopoeia related to traditional Chinese medicine are constantly improving Specifically speaking, from qualitative to quantitative, from single component to multi-component, from the control of heavy metals and agricultural residues to the gradual establishment of relevant standards, the standards of traditional Chinese medicine are gradually improving and upgrading "However, the application of traditional Chinese medicine is very wide In addition to the application in the field of medicine, it can also be used in food, health products, daily chemical products, etc Considering the different application fields, the limit standards for heavy metals and agricultural residues are also different If as a food application, there is no specific limit of treatment and dosage, it should be in accordance with the food limit standard As a drug, we should take into account the dosage, usage and other factors, combined with the international general method, and scientifically formulate the limit standard of Chinese herbal medicine " Yang Hongjun said In view of the frequent queries on the safety of traditional Chinese medicine by Chinese and foreign media in recent years, Yang Hongjun believes that at present, relevant departments urgently need to conduct in-depth research on the potential safety risks of traditional Chinese medicine "Once someone doubts, we can answer the safety problems of traditional Chinese medicine with scientific data, rather than just judging from experience and deriving from theory.".
