The emperor was called the son of heaven in ancient times. The emperor's greatest wish is to live with heaven, hoping to live forever like the legendary jade emperor, so the elixir dedicated to the emperor appeared. Can the elixir really make people live forever? What is this? The former question has long been confirmed by history and is nonsense. However, the latter remains a mystery, and no researcher can really understand it. Although some experts in chemical history said in their research papers that they had deciphered the composition of the "elixir of life", there was no physical or archaeological discovery to prove this. One thing is recorded like this: "Today, the Xu family in Qi wrote that there are three sacred mountains in the sea, named Penglai, the abbot and Yingzhou, where immortals live. Please fast and beg for boys and girls. So I sent thousands of boys and girls to the program to seek eternal life. " This happened in the twenty-eighth year of Qin Shihuang, that is, 2 19 BC. Xu Shi, also named Xu Fu, was a famous alchemist at that time. Ying Zheng sent him to sea with thousands of boys and girls. The purpose is to find the "elixir of life", that is, the elixir that can make you live forever. However, Xu didn't finish the task, and Ying Zheng didn't live forever. In July of the thirty-seventh year of Qin Shihuang, "the first emperor collapsed on the sand dune steps". Dune platform, in today's Xingtai City, Hebei Province. Travel in Ying Zheng, died unexpectedly. Historians have always suspected that he was murdered by Zhao Gao. However, the program did not find the elixir of life, but it led to a story with great historical suspense, that is, thousands of boys and girls who went with the program were afraid to return to China, and then crossed the island of Japan and became the ancestors of the Japanese. This is another story, so I won't show it here. At that time, Xu searched for many years but could not find the elixir. He is afraid of coming back. He told Ying Zheng that there were fish monsters in Penglai and they couldn't get ashore. Obviously this is Xu's lie, but Ying Zheng believed it, and sent people with superb archery to shoot arrows at sea. It is recorded in the history books that "Fang Shixu and others went to the sea to seek medicine. They are too old, too expensive and afraid of being punished. It is a lie to say that Penglai has medicine, but it often suffers from Spanish mackerel, so it can't come. Please shoot it with a crossbow. " The program didn't find the elixir, but the phenomenon of alchemy in ancient China emerged endlessly, and emperors in past dynasties also recorded taking the elixir. The most famous is Historical Records of the First Qin Emperor: "The emperor believed the alchemist and said," Breaking bait medicine is my life. "The" emperor "here refers to Sima Pi, the beloved emperor of the Jin Dynasty. : "After eating elixir, you get angry, and eunuchs around you are often convicted. If one person dies, everyone is in danger. "The top here is Chun-Li, Tang Xianzong. In the early days, Liu Mi and others were punished, but the alchemist recovered a little. Because of the progress left and right, he put. Just like his epigraphy, and the "business" here is right. : "Lured by the alchemist's elixir, I became more manic and less emotional." "Since autumn and winter, I have felt unwell, and the Taoist priest thinks I need to change my bones." "Business" here refers to Li Yan. The Dan medicine he took was refined by Taoist priests. When I was trapped by the alchemist, I felt impatient and thirsty, but outsiders didn't notice it. I was deeply suspicious. Hearing this, I bowed my head and said nothing. The "head" here is Li Chen, Emperor Xuanzong of the Tang Dynasty. But he said, "In August, Ding Chou made an admonition and took Dan medicine and died. "Minister Yang wine junior remonstrate Ming sejong Zhu Houxi can't take Dan medicine, was killed. : "It was this day that Li Ke, the official of the Red Temple, burned into a red pill. The object of Li Ke's incense burning is Zhu Changluo, the emperor of the Ming Dynasty. Emperors are so fascinated by Dan medicine, so what are these Dan medicines? Huan Kuan's Twenty-three Jin Jianji, written by Han people, said: "Immortals eat gold and drink pearls, and then live with heaven and earth." It can be seen that the elixir contains gold, silver and jewels. Records in 2000 proved that the elixir was made of jade. Among them, the top-grade substances that can be refined into elixir are Yuquan, Cinnabar, Mercury, Kong Qing, Zengqing, Bai Qing, Mica and Puxi.

Today, these substances are just some common medicinal materials, and some of them are even highly toxic, but ancient alchemists used them as secret recipes and extracted them for the emperor to take. Sand is one of the most important ingredients in ancient elixirs, and modern science has proved that it is a mineral containing elements such as mercury. But the ancients regarded it as a treasure. "Zi Tongzhi Ji Jian Tang Fifty-seven" said: "Dansha is sweet and slightly cold. Treat all five zang-organs diseases. Nourish the heart, soothe the nerves, benefit qi, improve eyesight and drive away evil spirits. I have served the gods for a long time. " Another important component of ancient "elixir" is "mercury", that is, the chemical mercury, which is very toxic. When Ying Zheng was building a mausoleum, mercury was injected into it to prevent it from being stolen. According to China's traditional medical viewpoint, "Mercury mainly treats scabies, scabies and baldness, and kills insects and lice in the skin", and it is also used as an abortion drug. Ancient alchemists found that mercury can "kill gold, silver, copper, tin and poison, melt them back into alchemy and serve the immortals for a long time." Yes-Yuquan, also known as Yuza, is a listed fairy jade. It tastes sweet and flat. Indications for all five zang-organs diseases. Strengthen bones and soothe the nerves, strengthen muscles and invigorate qi, endure cold and heat for a long time, and never die if you are not hungry. Yuquan has another special function. The ancients used it as a preservative for corpses and generally swallowed it before dying. "Take five pounds before death, and the color will remain unchanged for three years after death." Empty, attending cyanotic deafness. Improving eyesight and benefiting nine orifices, promoting blood circulation and nourishing the mind. Long-term service keeps your body light and keeps you from getting old. Zeng Qing tastes sour and slightly cold. Indications: eye pain, stopping tears, wind arthralgia, benefiting joints, dredging nine orifices, promoting digestion and resolving food stagnation. The light body is not old for a long time. White, sweet and flat. Proficient in improving eyesight, benefiting nine orifices, deafness and heart evil. Make people vomit and kill three poisonous insects. A man who serves the gods for a long time will never get old. It can cure red eyes, sore eyes, sore throat, vulva erosion pain, cold and heat drenching stones, blood in the abdomen, and all kinds of evil spirits, so that people can have children. You can't get old when you take the bait, but you can live longer when you take the bait for a long time. Orpiment is mainly used to treat sores, bald sores, antiviral insects, itching, germs and various poisons. After a long period of refining, you can be wise, you can be old, and you can not be old. With the above raw materials and accessories, you can make an elixir. This elixir can be made into solid pills or boiled into liquid. That is, solid elixir and liquid elixir, their pharmacology is the same, which is consistent with the existence of solid and liquid forms of modern drugs. How is the "elixir of life" made? According to the ancient saying that "the longer the burning time, the better the change", the so-called "elixir" can be obtained by burning at high temperature or denaturing substances that can react chemically to produce new substances. Dan medicine is divided into nine categories, of which the top grade is "Danhua". The process of alchemy is like this. Ge Hong, a famous scientist in Jin Dynasty, recorded it in detail in Zi Tongzhi Ji Jian Tang 59. "You do Huang Xuan first, with realgar water, ettringite water, Yan Rong, bittern, stone, oyster, halloysitum rubrum, talc, Hu Fen each dozens of jins, thought that the fire had passed on the 36th, and you were on the 7th. Take a pill as a pill, put it on a strong fire and it will turn into gold in a short time. Another 240 baht, plus mercury and 100 Jin of fire, becomes gold. What is successful in gold is also successful in medicine. No gold, no medicine, no fire, no days. " Judging from the above, this is not medicine, but smelting gold and silver. No wonder some professionals say that the earliest smelting technology in ancient China originated from alchemy medicine. It is said that you can live to be 200-300 years old even if you try a little. "Refine a person's body, so that a person can live forever. This concealment depends on external things to me, just like fat is always on fire and can't be extinguished. Coat your feet with slurry, and it won't rot in water. This is to string its meat with the power of copper. "
