In ancient China, various emperors sought the fabled elixir with varying results. In the Qin Dynasty, Qin Shi Huang sent Taoist alchemist Xu Fu with 500 young men and 500 young women to the eastern seas to find the elixir, but he never came back (legend has it that he found Japan instead). When Shi Huang Di visited, he brought 3000 young girls and boys, but none of them ever returned.
The ancient Chinese believed that ingesting long-lasting precious substances such as jade, cinnabar or hematite would confer some of that longevity on the person who consumed them. Gold was considered particularly potent, as it was a non-tarnishing precious metal; the idea of potable or drinkable gold is found in China by the end of the third century BC. The most famous Chinese alchemical book, the Danjing yaojue (Essential Formulas of Alchemical Classics) attributed to Sun Simiao (c. 581 — c. 682 CE),[2][3] a famous medical specialist respectfully called “King of Medicine” by later generations, discusses in detail the creation of elixirs for immortality (mercury, sulfur, and the salts of mercury and arsenic are prominent, and most are ironically poisonous) as well as those for curing certain diseases and the fabrication of precious stones.
Many of these substances, far from contributing to longevity, were actively toxic. Jiajing Emperor in the Ming Dynasty died from ingesting a lethal dosage of mercury in the supposed "Elixir of Life" conjured by alchemists. British historian Joseph Needham compiled a list of Chinese emperors whose deaths were likely due to elixir poisoning [reference?].
India[edit]
Amrita, the elixir of life, also known to Sikhs as "Amrit, the Nectar of Immortality" (see Amrit Sanskar), has been described in the Hindu scriptures. Anybody who consumes even a tiniest portion of Amrit has been described to gain immortality. The legend has it, at early times when the inception of the world had just taken place, evil demons had gained strength. This was seen as a threat to the gods who feared them. So these gods (including Indra, the god of sky, Vayu, the god of wind, and Agni, the god of fire) went to seek advice and help from the three primary gods according to the Hindus: Vishnu (the preserver), Brahma (the creator), and Shiva (the destroyer). They suggested that Amrit could only be gained from the samudra manthan (or churning of the ocean) for the ocean in its depths hid mysterious and secret objects. Vishnu agreed to take the form of a turtle on whose shell a huge mountain was placed. This mountain was used as a churning pole.
With the help of a Vasuki (mighty and long serpent, king of Nagloka) the churning process began at the surface. From one side the gods pulled the serpent, which had coiled itself around the mountain, and the demons pulled it from the other side. As the churning process required immense strength, hence the demons were persuaded to do the job – they agreed in return for a portion of Amrit. Finally with their combined efforts (of the gods and demons), Amrit emerged from the ocean depths. All the gods were offered the drink but the gods managed to trick the demons who did not get the holy drink.
The oldest Indian writings, the Vedas (Hindu sacred scriptures), contain the same hints of alchemy that are found in evidence from ancient China, namely vague references to a connection between gold and long life. Mercury, which was so vital to alchemy everywhere, is first mentioned in the 4th to 3rd century BC Arthashastra, about the same time it is encountered in China and in the West. Evidence of the idea of transmuting base metals to gold appears in 2nd to 5th century AD Buddhist texts, about the same time as in the West.
It is also possible that the alchemy of medicine and immortality came to China from India, or vice versa; in any case, for both cultures, gold-making appears to have been a minor concern, and medicine the major concern. But the elixir of immortality was of little importance in India (which had other avenues to immortality). The Indian elixirs were mineral remedies for specific diseases or, at the most, to promote long life.
