Elixir of immortality


The elixir of life, also known as elixir of immortality and sometimes equated with the philosopher's stone, is a mythical potion that supposedly grants the drinker eternal life and/or eternal youth. This elixir was also said to cure all diseases. Alchemists in various ages and cultures sought the means of formulating the elixir.

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), 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 and resulted in Chinese alchemical elixir poisoning. The 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.
