Qiu Xian asked, feathering ascension to heaven is the dream of many ancients, they are eager to live a long life and begin to study the refining of Dan medicine, but due to limited knowledge and cognition, most of the medicines refined are poisons, and Wushishan is one of the representatives. There is a story recorded in the Taiping Guangji, which can support our view, what is going on? Let me reveal the secrets to you.

The vice of the ancients in our country to seek immortals and ask for medicines, retrospectively began with Qin Shi Huang, as the first emperor, of course, he did not want to die early, so he sent people to travel far and wide, just to seek longevity medicine, driven by this wrong behavior, alchemy was popular at that time, and reached its peak in the Wei and Jin dynasties. As the founder of Wei Jin Metaphysics, He Yan naturally has his own "formula". According to the Song Dynasty Ge Hong record: He Yan made a medicine for internal use, made of sulfur, stalactite, chishi, Zeng Qing (natural copper sulfate) and gravel five kinds of stone, so it is called "five stone scatter".
According to the records of later generations, the various medicinal materials in the five stones scatter are extremely hot things, people will have a full body fever after taking it, legend has it that He Yan was hollowed out by the color of wine, after taking the five stones, he actually felt clear, so the five stones began to circulate in the scholar class, until the Tang Dynasty, only began to be refuted by the five stones scatter this prescription, he is the medicine king Sun Simiao, he believes that the five stones scatter has excessive burning, when used "must not be careless", and even personally removed the sulfur and red stone two kinds of medicinal materials, invented the "medicinal effect" lighter three stone scatter.
Whether it is five-stone scatter or three stone scatter, in the final analysis, it is necessary for the human body to ingest some toxic compounds. After taking, although it will not be killed immediately, the so-called "clear mind" is actually a kind of increase in the flow rate of blood through medicinal properties, so that people can react quickly in a certain period of time, and the body function is enhanced. But also because they are hidden and confusing, which led to the mainstream of the society at that time, flocking to them. In fact, even Sun Simiao, the "creator" of the three-stone scatter, once called on the world to "encounter this (five stone scatter) square, that is, it must be burned, and it should not stay for a long time."
Next, we may wish to change our perspective and look for some interesting clues from ancient books, such as "Wang Cang" in the Taiping Guangji Tomb (volume 389). As one of the seven sons of Jian'an, Wang Cang's talent does not need to be doubted, his poetry is given the crown of the seven sons of Jian'an, and his official position has also achieved the Marquis of Guannei, which shows that his life is what we envy. The Taiping Guangji records such a small story, saying that once Wang Cang accompanied Cao Cao on his northern expedition to Wuhuan, climbed the mountain ridge and looked into the distance, and found a mountain hill without grass.
There is a strangest place in this mountain, there is no grass on the mountain, there is no chemical pollution during the Wei and Jin Dynasties, so why is that? After careful observation, Wang Yue came to the conclusion that there must be an ancient tomb here, and the tomb owner must have taken a large amount of ore before his death, Cao Cao felt very confused after hearing this, so he ordered someone to dig it up, and sure enough, he found that there was an ancient tomb under the hill, and the tomb was actually filled with gravel.
Cao Cao naturally did not understand, Wang Cang quickly explained, although the stone is an important "medicinal material" of the alchemist, but in fact, it contains severe poison, even if buried under the soil layer, its toxicity will gradually spread out, and the final result is to cause no grass here, so the so-called elixir refined must be taken carefully! As one of the raw materials of the five-stone dispersion, a single stone has such a powerful toxicity, the grass and trees can not survive, the damage to the human body is obvious, if you add other four flavor raw materials, is this five-stone powder "chronic poison"?
Chinese culture has a long history, broad and profound, some of which are essences, but also some bad. Since there is no chemical basis, it began to arbitrarily formulate some substances, alchemy is actually a failed study of the ancients, so this outdated and harmful "custom" should be abandoned by modern people, only by taking its essence and removing its dross, our country's culture can continue to progress and develop!
