What drugs contain lead in drugs?
In the normal modern medical system, there were no drugs that specifically contained lead. However, in some traditional folk prescriptions, folk self-made pills, or some traditional Chinese medicine made by some unofficial Chinese medicine stores, lead may exceed the standard. For example, the "scorpion pill" of a Chinese medicine store in Chengdu was suspected to contain lead, causing lead poisoning in children's blood.(The test results provided by one of the parents showed that the lead content was as high as 286.23 milligrams per kilogram, but the Chinese medicine store said that the same batch of tests was only 0.14 milligrams per kilogram, and further investigation was needed.) There were also five good friends who had excessive blood lead after eating the pills made by the local doctor. The test found that the lead content of the pills was as high as 130,000 milligrams per kilogram. It should be noted that these are not the components of regular drugs. The growth of Chinese herbal medicines may be affected by many factors, which may lead to excessive lead. The production process of Chinese patent medicine may also be mixed with lead. Therefore, when choosing Chinese medicine, you should choose regular hospitals, large-scale, brand-name, reputable drugstores, and traditional Chinese medicine pieces and Chinese patent medicines produced by regular manufacturers, and take them according to the doctor's advice. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
