Process and purpose

By refining bases into gold and ingesting the "fake" or synthetic gold, the alchemist believed that immortal life would be delivered. The idea that fake gold was superior to real gold arose because the alchemists believed the combination of a variety of substances (and the transformation of these substances through roasting or burning) gave the final substance a spiritual value, possessing a superior essence when compared to natural gold. Gold and

(''jindan'') were the most sought-after substances to manipulate and ingest, believed to have longevity and thus able to elongate the life of the consumer. Cinnabar is a mineral with a reddish-brown colour and is the most common source of mercury in nature. The significance of its red colour and difficulty with which it was refined implied to alchemists its connection with the search for immortality. The colour was significant to symbolic belief as well, red being considered in Chinese culture to be the "zenith of the colour representing the sun, fire, royalty and energy." Cinnabar could also be roasted, which produced a liquid form of silver known as quicksilver, now known as mercury. This substance was ingested but it could also be combined with sulphur and burned again to return to its natural form of cinnabar, the solid seen as the yang to quicksilver's

provinces in central China. Although the majority of ''xian'' (immortality) elixirs were combinations of ''jindan'', many other elixirs were formed by combining metallic bases with natural herbs or animals bi-products. The rhinoceros' horn was commonly used in medicines and elixirs and was held to have fertility-increasing abilities. Elixirs were composed of metallic compounds such as gold and silver, but could also be made of more lethal components like arsenic, and sulphur.


East Asian vs Eastern Mediterranean views

Both the Eastern practice and the later Western practice of

are remarkably similar in their methods and ultimate purpose. To be sure, the desire to create an elixir of immortality was more appealing to the Taoists, but European alchemists were not averse to seeking out formulas for various longevity-boosting substances. The secret of transmuting one element into another, specifically

s into gold or silver, was equally explored by both schools for obvious reasons. In the European outlook, the ability to turn relatively worthless materials into gold was attractive enough to allow medieval alchemy to enjoy extensive practice long after the Chinese form had been forgotten. Alternatively, transmutation was also a means of accruing the precious metals that were key in making life-extending elixirs, and were otherwise expensive and difficult to obtain. Alchemical knowledge in the East and West favored different opinions of the true form of alchemy due to different

nature. Chinese alchemy specifically was consistent in its practice from the beginning, and there was relatively little controversy among its practitioners. Definition amongst alchemists varied only in their medical prescription for the elixir of immortality, or perhaps only over their names for it, of which

has counted about 1000. Because the Chinese approach was through the fundamental doctrine of ''Yin'' and ''Yang'', the influence of the '' I Ching'', and the teachings of the Five Elements, Chinese alchemy had its roots considerably more in obtaining a higher mental-spiritual level. In the West, there were conflicts between advocates of herbal and "chemical" (mineral) pharmacy, but in China, mineral remedies were always accepted. In Europe, there were conflicts between alchemists who favored gold-making and those who thought medicine the proper goal, but the Chinese always favored the latter. Since alchemy rarely achieved any of these goals, it was an advantage to the Western alchemist to have the situation obscured, and the art survived in Europe long after Chinese alchemy had simply faded away.


Origins

Despite much research, many scholars are still unable to marshal conflicting evidence in order to determine when exactly Chinese alchemy started. It was thought that China was making gold about one thousand years before Confucius' time, but this is contradicted by other academics stating that during the 5th century BCE there was no word for gold and that it was an unknown metal in China. However, despite the uncertain origins, there are enough similarities in the ideas of practices of Chinese alchemy and the Daoist tradition so that one can conclude that Laozi and

are the creators of this tradition. In her article, Radcliffe tells that Zhang rejected serving the Emperor and retreated to live in the mountains. At this time, he met Laozi and together they created (or attempted to create) the Elixir of Life (Radcliffe, 2001), by creating the theory that would be used in order to achieve the making of such an elixir. This is the starting point to the Chinese tradition of alchemy, whose purpose was to achieve immortality. One of the first evidence of Chinese alchemy being openly discussed in history is during the Qin's First Emperor's period when Huan Kuan (73-49 BC) states how modifying forms of nature and ingesting them will bring immortality to the person who drinks them. Before Huan Kuan, the idea of alchemy was to turn base metals into gold. Conflicting research on the origins of alchemy are further demonstrated by Cooper, who claims that alchemy "flourished well before 144 BCE, for at that date the Emperor issued an edict which ordered public execution for anyone found making counterfeit gold". This suggests that people were well aware of how to heat the metals in order to change them into a desired form. A further counter to Pregadio from Cooper is the latter's contention that an emperor in 60 BCE had hired "a well-known scholar, Liu Hsiang, as Master of the Recipes so that he could make alchemical gold and prolong the Emperor's life." All of these conflicting origins considered, it is nearly impossible to claim any absolute knowledge on the origins of Chinese alchemy. However, historical texts of Daoist teaching include alchemical practices, most of which posit the existence of an elixir or the Golden Elixir that, when ingested, gives the drinker eternal life. As there is a direct connection between Daoism and Laozi, some suggest he played a major role in the creation of Chinese alchemy.

Yin and Yang

The concept of yin-yang is pervasive throughout Chinese alchemical theory. Metals were categorized as being male or female, and mercury and sulphur especially were thought to have powers relating to lunar and solar respectively. Prior to Taoist tradition, the Chinese already had very definitive notions of the natural world's processes and "changes", especially involving the ''

'': Water, Fire, Earth, Metal and Wood. These were commonly thought to be interchangeable with one another; each were capable of becoming another element. The concept is integral, as the belief in outer alchemy necessitates the belief in natural elements being able to change into others. The cyclical balance of the elements relates to the binary opposition of yin-yang, and so it appears quite frequently.


Outer and inner alchemy

Chinese alchemy can be divided into two methods of practice, ''

. Waidan refers to practices relating to the process of making an elixir often containing herbal or chemical substances found outside of the body. This process involves esoteric oral instructions, building a laboratory, kindling and sustaining the special fires used in the production process, rules of seclusion and purification for the alchemist to follow, and various practices including the performance of ceremonies to protect the self and the ritual area. Waidan can also include following a dietary regimen which prescribes or proscribes certain foods. Preparing medicines and elixirs can be referred to as outer practices or waidan as these practices occur outside of the body until they are verified by the ingestion of medicines, herbs, and pills to bring about physical changes within the body, separate to the soul.


Inner alchemy (Neidan)

The term Neidan can be divided into two parts: Nei, meaning inner, and Dan, which refers to alchemy, elixir, and cinnabar (mercury). Neidan uses techniques such as: composed meditation techniques, visualization, breathing and bodily posture exercises. Breathing exercises were used to preserve jing or "life essence" and bodily postures were used to improve qi or "energy" flow in the body. Neidan comprises the elixir from the principles of

and the cultivation of substances already present in the body, in particular the manipulation of three substances in the body known as the "Three Treasures". The three treasures are: # Jing which can be translated as "life essence". A person is born with Jing and it governs the developmental growth processes in the body. Since people are born with a certain amount of Jing, it is taught that a person can increase their Jing through dietary and lifestyle practices. # Qi which can be translated as "energy" or "vital energy". Qi energy results from the interaction of yin and yang. A healthy body is constantly circulating Qi. # Shen can be translated as "spirit" or "mind". Shen is the energy used in mental, spiritual and creative functioning (Lu, 30). The three treasures are also associated with locations in the body where the alchemical process takes place. These locations include major organs and energy centers, called

s. #Jing or "life essence" is found in the Kidneys and possibly the adrenal glands. #Qi or "vital energy" resides in Lower Dantian or "elixir field" and it is located about an inch down from navel. #Shen or "spiritual energy" is seated in the Middle Dantian, which is the Heart. During the Han dynasty and after, Neidan and Daoist martial arts gradually merged into one, becoming Neijia martial arts. Famous Taijiquan masters who practiced Neijia include Wu Tunan (吳圖南) and Chen Weiming (陳微明).


Associated risks

When ingested, these compounds did not always result in the desired outcome. Many individuals died or had psychological difficulties after taking certain elixirs. However, the loss of life may not have seemed a large risk, when compared with the promise of the afterlife. Although these elixirs were lethal or dangerous, there is some contention that these individuals were not ignorant of the fatality of some of the materials they were ingesting. There were certain grades of immortality, so if the practiced alchemist died, the level of immortality they achieved was determined by their corpse. If their corpse was sweet-smelling, it was said that they had achieved immortality in an ephemeral state. Likewise, if their corpse disappeared, leaving behind only the clothes, such as in the death of an adept named Ko Hung, this was another form of immortality known as ''shih chieh hsien'' (corpse-free immortals) (Cooper, 14).


Conception of medicine

Medicines can be used to heal ailments on the exterior or interior of the body, to control the ageing of the body, or even to prevent death. The term medicine and elixir are virtually interchangeable because of the array of ailments they can influence. The difference between defining an elixir from a medicine was that many medicines were composed mainly of all natural products like herbs and animal products. Never the animals themselves, only their products, which could consist of dung or fur. Although metal compounds are more potent when curing ailments, herbs were used because they were easier to combine and more abundantly available. To make medicines one would use ingredients like: Kolo nuts, which would be used in famous longevity pills like "Fo-Ti-Ti";

Practitioners


Chinese women alchemists

With the rise of alchemy in Chinese civilization, alchemy began to be seen as an art. Among many practitioners, a significant number of women were known to have mastered this art. The earliest recorded woman alchemist had the family name of Fang (), and lived around the first century B.C. Raised in a scholarly family skilled in the alchemical arts, she studied alchemy with one of the Emperor Han Wu Ti's spouses, and therefore had access to the highest levels of society. Fang was credited with the discovery of the method to turn mercury into silver. It was believed that she may have used the chemical technique of silver extraction from
ore Ore is natural rock or sediment that contains one or more valuable minerals, typically containing metals, that can be mined, treated and sold at a profit.Encyclopædia Britannica. "Ore". Encyclopædia Britannica Online. Retrieved 7 Apr ...
s using mercury, where pure silver residue is left behind from the boiled mercury. Fang's husband was Cheng Wei (;see :zh:程偉). Details of Fang's life were recorded by author and alchemist Ge Hong. Keng Hsien-Seng (circa A.D. 975) was another female alchemist who, according to the science writings of Wu Shu "mastered the art of the yellow and white lchemywith many other strong transformations, mysterious and incomprehensible". Wu Shu also described Keng as being acquainted with other Taoist techniques and was believed able to control the spirits. She also mastered the transformation of mercury and "snow" into silver, probably using the technique of extraction of silver from its ores, as well as using a primitive type of Soxhlet process to continuously extract camphor into alcohol. Other female alchemists who have been recognized in Chinese literature are Pao Ku Ko (third century A.D.), Thai Hsuan Nu, Sun Pu-Eh (12th century), and Shen Yu Hsiu (15th century).
