External Alchemy and the Quest for Gold Transmutation

Why is Taoist external alchemy also called "Golden Elixir Art" or "Yellow-White Art"? Baopuzi Inner Chapters·Golden Elixirs states: "Once the divine elixir is successfully made, it not only grants longevity but also can be used to make gold." Why is there a need to transform base metals into gold? Wei Boyang wrote in The Zhouyi Cantongqi: "Gold is incorruptible and indestructible, thus it is the treasure of all things." Minerals such as gold, silver, and jade in nature are stable in property and not prone to decay or change. Therefore, alchemists believed that if humans ingest these "incorruptible" substances like gold, silver, and jade, their properties could be transferred to the human body, making the flesh-and-blood body equally "incorruptible". This further led to the practice of refining gold and silver through alchemical methods—specifically, burning mercury (quicksilver) with base metals such as lead, copper, and iron in different proportions to produce yellow or white gold or silver. Hence, external alchemy is also known as "Golden Elixir Art" or "Yellow-White Art".

Such medicinal gold and medicinal silver produced in external alchemy were quite precious in ancient times. As the saying goes, "The success of gold-making signifies the success of the elixir." In the eyes of ancient alchemists, whether the refined divine elixir could transform base metals into gold or silver was regarded as an important sign of the success of cultivation. If the transmutation failed, it was necessary to adjust the fire according to the changes of the hexagrams and lines, repeatedly refine it, and eventually form the elixir after nine transformations. Due to its transmuting effect, it was also called the "elixir mother".

Historical Exchange Timeline

2nd Century BCE

Chinese Origins: External alchemy emerges in Han Dynasty court, seeking immortality elixirs.

1st-3rd Century CE

Western Origins: Hellenistic alchemy develops in Alexandria, combining Greek philosophy with Egyptian practices.

8th-9th Century

Islamic Bridge: Islamic scholars translate and synthesize both traditions, creating new alchemical works.

13th-14th Century

Mongol Connections: Expanded trade routes facilitate direct exchange of alchemical knowledge.

16th-17th Century

Jesuit Transmission: European missionaries document Chinese practices, bringing knowledge to the West.

Key Insight: Convergent Evolution

The striking similarities between Chinese and Western alchemy suggest a form of "convergent evolution" in human knowledge systems. Despite developing independently, both traditions arrived at remarkably similar conclusions about the nature of matter, transformation, and the relationship between the physical and spiritual realms. This convergence points to universal patterns in human understanding of natural phenomena.
