Chinese Alchemy
Chinese alchemy (煉丹術 ''liàndānshù'' "method for refining cinnabar") is a historical Chinese approach to alchemy. According to original texts such as the Cantong qi, the body is understood as the focus of cosmological processes summarized in the five agents of change, or Wuxing, the observation and cultivation of which leads the practitioner into alignment and harmony with the Tao. Therefore, the traditional view in China is that alchemy focuses mainly on longevity and the purification of one's spirit, mind and body, providing, health, longevity and wisdom, through the practice of Qigong and wuxingheqidao. The consumption and use of various concoctions known as alchemical medicines or elixirs, each of which having different purposes but largely were concerned with immortality. ''Pao zhi'' (炮制; ''Pao chi'') or Processing (Chinese materia medica) is used in Traditional Chinese Medicine, such as honey or wine frying and roasting with toxic metals such as mercury, ...

Obed Simon Johnson
Obed Simon Johnson (May 5, 1881[Obed Simon Johnson, “John Peter Johnson” in Lost Grove Township, 1869-1969, compiled by the Committee of the Harcourt Commercial Club. Gowrie, Iowa: The Gowrie News, 1970, page 85] – October 12, 1970) was an American academic, chaplain, congregational missionary and student of Chinese culture and history, known for ''A Study of Chinese Alchemy'', which attributes the origin of alchemy to ancient China, rather than Greco-Egyptians 500 years later.[Obed Simon Johnson, A Study of Chinese Alchemy, Shanghai, Commercial P, 1928. rpt. New York: Arno P, 1974.] He was the first Westerner to recognize the ancient Chinese alchemists. Johnson was an early and pioneering sinologist. Johnson's contributions were translation, collation and synthesis of Chinese alchemy from many of the Chinese classics and books. He then made western scholars aware that one of the central tenets in chemistry, the elixir concept emerged far earlier in China than in Europe (i.e ...

Pill Of Immortality
The Pill of Immortality, also known as xiandan (仙丹), (金丹) or (丹) in general, was an elixir or pill sought by Chinese alchemists to confer physical or spiritual immortality. It is typically represented as a spherical pill of dark color and uniform texture, made of refined medical material. Colloquially and in Chinese medicine, the term can also refer to medicine of great efficacy. The search for the pill was started several centuries BC ago and continued until 500 AD and was often based on noble metals such as mercury and gold. Its search was supported by the emperors and the nobility of China, with a strong tradition in Taoism. During the Qin dynasty, the founding Emperor Qin Shi Huang consulted sages and alchemists to seek such a pill to achieve eternal life. The alchemical tradition in China was divided into two differing schools in the search for the pill of immortality. Taoist sects which advocated the attainment of immortality by consuming substances were ve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Precious Metal
Precious metals are rare, naturally occurring metallic chemical elements of high Value (economics), economic value. Precious metals, particularly the noble metals, are more corrosion resistant and less reactivity (chemistry), chemically reactive than most elements. They are usually ductile and have a high Lustre (mineralogy), lustre. Historically, precious metals were important as currency but they are now regarded mainly as investment and industrial raw material, raw materials. Gold, silver, platinum, and palladium each have an ISO 4217 currency code. The best known precious metals are the precious coinage metals, which are gold and silver. Although both have industrial uses, they are better known for their uses in art, jewellery, jewelry, and coinage. Other precious metals include the platinum group metals: ruthenium, rhodium, palladium, osmium, iridium, and platinum, of which platinum is the most widely traded. The demand for precious metals is driven not only by their pra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transmutation Of Elements
Nuclear transmutation is the conversion of one chemical element or an isotope into another chemical element. Nuclear transmutation occurs in any process where the number of protons or neutrons in the nucleus of an atom is changed. A transmutation can be achieved either by nuclear reactions (in which an outside particle reacts with a nucleus) or by radioactive decay, where no outside cause is needed. Natural transmutation by stellar nucleosynthesis in the past created most of the heavier chemical elements in the known existing universe, and continues to take place to this day, creating the vast majority of the most common elements in the universe, including helium, oxygen and carbon. Most stars carry out transmutation through fusion reactions involving hydrogen and helium, while much larger stars are also capable of fusing heavier elements up to iron late in their evolution. Elements heavier than iron, such as gold or lead, are created through elemental transmutations that can na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Base Metal
A base metal is a common and inexpensive metal, as opposed to a precious metal such as gold or silver. In numismatics, coins often derived their value from the precious metal content; however, base metals have also been used in coins in the past and today. Specific definitions In contrast to noble metals, base metals may be distinguished by oxidizing or corroding relatively easily and reacting variably with diluted hydrochloric acid (HCl) to form hydrogen. Examples include iron, nickel, lead and zinc. Copper is also considered a base metal because it oxidizes relatively easily, although it does not react with HCl. In mining and economics, the term base metals refers to industrial non-ferrous metals excluding precious metals. These include copper, lead, nickel and zinc. The U.S. Customs and Border Protection agency is more inclusive in its definition of commercial base metals. Its list includes—in addition to copper, lead, nickel, and zinc—the following metals: iron and ste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhinoceros
A rhinoceros ( ; ; ; : rhinoceros or rhinoceroses), commonly abbreviated to rhino, is a member of any of the five extant taxon, extant species (or numerous extinct species) of odd-toed ungulates (perissodactyls) in the family (biology), family Rhinocerotidae; it can also refer to a member of any of the extinct species of the superfamily Rhinocerotoidea. Two of the extant species are native to Africa, and three to South Asia, South and Southeast Asia. Rhinoceroses are some of the largest remaining megafauna: all weigh over half a tonne in adulthood. They have a herbivore, herbivorous diet, small brains for mammals of their size, one or two horns, and a thick , protective skin formed from layers of collagen positioned in a crystal structure, lattice structure. They generally eat leafy material, although their ability to ferment food in their colon (anatomy), hindgut allows them to subsist on more fibrous plant matter when necessary. Unlike other perissodactyls, the two African ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xian (Taoism)
A ''xian'' ( zh, s=仙, t=僊, p=xiān, w=hsien) is any manner of immortal or mythical being within the Taoist Pantheon (religion), pantheon or Chinese folklore. has often been translated into English as "immortal" or "wizard". Traditionally, ''xian'' refers to entities who have attained immortality and supernatural or Magic (supernatural), magical abilities later in life, with a connection to the heavenly realms inaccessible to mortals. This is often achieved through spiritual Self-cultivation#Taoism and the authentic self, self-cultivation, Chinese alchemy, alchemy, or worship by others. This is different from the Deity, gods (Deity, deities) in Chinese mythology and Taoism. ''Xian'' is also used as a descriptor to refer to often benevolent figures of great historical, spiritual and cultural significance. The Quanzhen School of Taoism, Daoism had a variety of definitions for during its history, including a metaphorical meaning where the term simply means a good, principl ...

Yin And Yang
Originating in Chinese philosophy, yin and yang (, ), also yinyang or yin-yang, is the concept of opposite cosmic principles or forces that interact, interconnect, and perpetuate each other. Yin and yang can be thought of as complementary and at the same time opposing forces that interact to form a dynamic system in which the whole is greater than the assembled parts and the parts are as important for the cohesion of the whole. In Chinese cosmology, the universe creates itself out of a primary chaos of primordial qi or material energy, organized into the cycles of yin and yang, force and motion leading to form and matter. "Yin" is retractive, passive and contractive in nature, while "yang" is repelling, active and expansive in principle; this dichotomy in some form, is seen in all things in nature—patterns of change and difference. For example, biological, psychological and seasonal cycles, the historical evolution of landscapes over days, weeks, years to eons. The origin ...
