朱砂为硫化物类矿物辰砂族辰砂。主含硫化汞,其次含镁、铁、铜、铋、锰、锑、砷等多种微量元素。朱砂的主要作用是清心镇惊,安神解毒,而另一方面汞、铋、锑、砷等重金属微量元素对人体都有毒性,其中尤以汞的含量最高,对人体的危害也最大,因为汞与蛋白质中的巯基有特别的亲和力,口服朱砂经消化道吸收后,游离汞与血液中血红蛋白和血浆蛋白结合,随血液循环进入人体各组织器官,损害肝肾等,引起一系列中毒症状,如少尿、尿闭、尿毒症、恶心、呕吐、腹泻、浓血便,里急后重。血中汞浓度高时,可穿过血脑屏障,直接损害中枢神经,出现汞毒性震颤,严重者可致死亡。
The cinnabar is a cinnabar-based cinnabar sand. The main mercury sulfide, followed by magnesium, iron, copper, antimony, manganese, antimony, arsenic and other trace elements. The main role of cinnabar is pure heart and panic, soothe the nerves to detoxify, and on the other hand, trace elements such as mercury, antimony, bismuth, arsenic and other heavy metals are toxic to the human body, especially the highest level of mercury, the greatest harm to the human body, because mercury It has a special affinity with the sulfhydryl group in the protein. After oral administration of cinnabar is absorbed through the digestive tract, free mercury is combined with hemoglobin and plasma proteins in the blood, and enters the body’s tissues and organs with the blood circulation, damaging the liver and kidneys, and causing a series of poisoning symptoms. Oliguria, urination, uremia, nausea, vomiting, diarrhea, bloody stools, tenesmus. When the concentration of mercury in the blood is high, it can cross the blood-brain barrier and directly damage the central nervous system. Mercury toxicity tremor occurs, and severe cases can cause death.
