Current review: is the heavy metal of dead card of medicinal materials and pieces of decoction a waste of food due to choking?

In food, it's OK to eat every day When you get to the medicine, you'll be able to turn over the river? No 16 National Pharmacopoeia Committee promulgated the "announcement on the revised draft of general principles for the determination of medicinal materials and decoction pieces, Vol 4, 2015 edition of Chinese Pharmacopoeia" Among them, "lead, cadmium, arsenic, mercury and copper in medicinal materials and pieces (plants) shall not exceed 5mg / kg, 1mg / kg, 2mg / kg, 0.2mg/kg and 20mg / kg respectively." The limits of these indicators have caused a great stir in the pharmaceutical industry Since most of these are ultimately used for oral use, let's refer to the national provisions of food for interpretation For such indicators, they are all pollutants According to the requirements of gb2762-2017 national food safety standard limit of pollutants in food, the limit of lead in tea and dried chrysanthemum in food is the same as that in Pharmacopoeia, and the limit is 5mg / kg The limit of cadmium is 1mg / kg, which is the same as that of the kidney (meat and meat products) of livestock and poultry However, the limit of cadmium content in aquatic animals and their products is 2.0mg/kg after the viscera is removed That is to say, the content of this kind of food can be higher than that of medicinal materials The limit of arsenic is 2mg / kg, which is indeed higher than that of food The limit of fresh vegetables, mushroom products, meat products, even cocoa products and chocolate is 0.5mg/kg The limit of mercury is 0.2mg/kg, twice that of edible salt, edible fungus and products As for the limit of copper 20mg / kg, unfortunately, there is no definition in the national standard The father of toxicology, Paracelsus, once said that only dose determines whether a thing is a poison In other words, it's not rigorous to talk about toxicity without dosage According to the above statistics, we will roughly analyze the logical defects of the heavy metal project of xiayinpian and medicinal materials First of all, how many ordinary and qualified foods can you eat to reach the test quantity of drugs? "Twice the amount of tea, dried chrysanthemums; half the amount of squid, abalone; four times the amount of chocolate; twice the amount of mushrooms." Secondly, how much can be achieved in a normal oral medication? "Let's count by meal I used to eat two bags of Longfeng's 70g instant noodles for a meal, and I can also eat two bags of eggs and vegetable leaves Roughly, it's about half a kilo to be converted into dry goods So can drinking beer and eating a jin of squid in summer be poisoned? Can a jin of mushroom be poisoned? I know that I usually hate people enough, who wants to make me poisoned legally? According to quadruple quantity, buy me two Jin of chocolate, I'll live feed you! Do not replace cocoa butter, according to the national standard cocoa products to buy Since it may be greasy and the key is expensive, please allow me to eat it in a week I want to have more days to satisfy my appetite " Is it toxic? If it's toxic, we really can't eat at ordinary times Moreover, we eat or all into the stomach, many pieces are only soup, do not eat slag The relevant content is even more discounted What's more, we eat food every day, and the drugs can't reach this frequency and dosage Since it is safe for human body in food, how can it play an important side effect in medicine? On the one hand, we all know that plant medicine grows in the same soil as crops How to divide it into drugs, we need to raise a step? These content indicators can not be used to control the efficacy of the project, nor can they cause public health crisis Why do you want to hold on? What is the rationality of its implementation? Any toxic control needs a certain purity of toxic substances Are these risks taken into account in the detection process? Heavy metal excess is certainly an impact on the human body, but there is also a process from quantitative change to qualitative change This unrealistic method of calibration is undoubtedly a waste of food due to choking According to this idea, it is not far from the construction of medical grade sunlight and medical grade cultivated land It is suggested that the testing organizations responsible for drafting should consult with clinicians or even experts in nutrition when setting standards, instead of testing for testing Traditional Chinese medicine, which is in a declining state, should not go into the abyss of eternal doom because the standard card is too dead Reference materials: gb2762-2017 national food safety standard limit of pollutants in food is reprinted by yaozhi.com The copyright belongs to the original author The purpose of reprinting is to transmit more information and does not represent the view of this platform If the content of the work, copyright and other issues are involved, please contact our website message, we will delete the content in the first time.
