Elixir Of Immortality
The elixir of life, also known as elixir of immortality, is a 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. History Ancient Mesopotamia An early mention of an elixir of life is found in the Epic of Gilgamesh (from the 2nd millennium BC) in which Gilgamesh comes to fear his own declining years following the death of his beloved companion Enkidu. He seeks out Utnapishtim, a Noah-like figure in Mesopotamian mythology in which he was a servant of the great Alchemist of the rain who later became immortal, to seek out the advice of the King of Herod of the Land of Fire. Gilgamesh is directed by him to find a plant at the bottom of the sea which he does but seeks first to test it on an old man before trying it himself. Unfortunately, it is eaten by a serpent before he can do so. China Many rulers of ancient China ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Mount Penglai
Penglai () is a legendary land of Chinese mythology. It is known in Japanese mythology as Hōrai.McCullough, Helen. ''Classical Japanese Prose'', p. 570. Stanford Univ. Press, 1990. . Location According to the ''Classic of Mountains and Seas'', the mountain is located at the eastern end of Bohai Sea. According to the pre-Qin mythology which retells the legend of Xu Fu presenting a memorial to the Qin Emperor in order to seek for the elixir of life, there are three godly mountains which are found in the Bohai sea where immortals reside; these mountains are Penglai, Fāngzhàng (), and Yíngzhōu (/). Other islands where immortals reside are called Dàiyú () and Yuánjiāo (). In the ''Illustrated Account of the Embassy to Goryeo in the Xuanhe Era'' (; ''Xuanhe fengshi Gaoli tujing''), written in 1124 by Xu Jing (徐兢), Mount Penglai is located on an inhabited island which is found within the boundaries of Changguo prefecture and can be reached "after crossing thirty thousa ...

Amrita
''Amrita'' ( sa, अमृत, IAST: ''amṛta''), ''Amrit'' or ''Amata'' in Pali, (also called ''Sudha'', ''Amiy'', ''Ami'') is a Sanskrit word that means "immortality". It is a central concept within Indian religions and is often referred to in ancient Indian texts as an elixir. Its first occurrence is in the Rigveda, where it is considered one of several synonyms for ''soma'', the drink of the devas. Amrita plays a significant role in the Samudra Manthana, and is the cause of the conflict between devas and asuras competing for amrita to obtain immortality. Amrita has varying significance in different Indian religions. The word ''Amrit'' is also a common first name for Sikhs and Hindus, while its feminine form is ''Amritā''. Amrita is cognate to and shares many similarities with ambrosia; both originated from a common Proto-Indo-European source."Ambrosia" in ''Chambers's Encyclopædia''. London: George Newnes, 1961, Vol. 1, p. 315. Etymology Amrita is composed of the negat ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Ming Dynasty
The Ming dynasty (), officially the Great Ming, was an Dynasties in Chinese history, imperial dynasty of China, ruling from 1368 to 1644 following the collapse of the Mongol Empire, Mongol-led Yuan dynasty. The Ming dynasty was the last orthodox dynasty of China ruled by the Han Chinese, Han people, the majority ethnic group in China. Although the primary capital of Beijing fell in 1644 to a rebellion led by Li Zicheng (who established the short-lived Shun dynasty), numerous rump state, rump regimes ruled by remnants of the House of Zhu, Ming imperial family—collectively called the Southern Ming—survived until 1662. The Ming dynasty's founder, the Hongwu Emperor (r. 1368–1398), attempted to create a society of self-sufficient rural communities ordered in a rigid, immobile system that would guarantee and support a permanent class of soldiers for his dynasty: the empire's standing army exceeded one million troops and the naval history of China, navy's dockyards in Nanjin ...

Chinese Alchemical Elixir Poisoning
In Chinese alchemy, elixir poisoning refers to the toxic effects from elixirs of immortality that contained metals and minerals such as mercury and arsenic. The official ''Twenty-Four Histories'' record numerous Chinese emperors, nobles, and officials who died from taking elixirs to prolong their lifespans. The first emperor to die from elixir poisoning was likely Qin Shi Huang (d. 210 BCE) and the last was the Yongzheng Emperor (d. 1735 AD). Despite common knowledge that immortality potions could be deadly, fangshi and Daoist alchemists continued the elixir-making practice for two millennia. Terminology The etymology of English elixir derives from Medieval Latin ''elixir'', from Arabic إكسير (''al-ʾiksīr''), probably from Ancient Greek ξήριον (''xḗrion'' "a desiccative powder for wounds"). ''Elixir'' originated in medieval European alchemy meaning "A preparation by the use of which it was sought to change metals into gold" (elixir stone or philosopher's stone) ...

Arsenates
The arsenate ion is . An arsenate (compound) is any compound that contains this ion. Arsenates are salts or esters of arsenic acid. The arsenic atom in arsenate has a valency of 5 and is also known as pentavalent arsenic or As(V). Arsenate resembles phosphate in many respects, since arsenic and phosphorus occur in the same group (column) of the periodic table. Arsenates are moderate oxidizers, with an electrode potential of +0.56 V for reduction to arsenites. Occurrence Arsenates occur naturally in a variety of minerals. Those minerals may contain hydrated or anhydrous arsenates. Unlike phosphates, arsenates are not lost from a mineral during weathering. Examples of arsenate-containing minerals include adamite, alarsite, annabergite, erythrite and legrandite. Where two arsenate ions are required to balance the charge in a formula, it is called diarsenate for example trizinc diarsenate, Zn3(AsO4)2. Ions The word arsenate is derived from arsenic acid, H3AsO4. This moder ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Sulphur
Sulfur (or sulphur in British English) is a chemical element with the symbol S and atomic number 16. It is abundant, multivalent and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S8. Elemental sulfur is a bright yellow, crystalline solid at room temperature. Sulfur is the tenth most abundant element by mass in the universe and the fifth most on Earth. Though sometimes found in pure, native form, sulfur on Earth usually occurs as sulfide and sulfate minerals. Being abundant in native form, sulfur was known in ancient times, being mentioned for its uses in ancient India, ancient Greece, China, and ancient Egypt. Historically and in literature sulfur is also called brimstone, which means "burning stone". Today, almost all elemental sulfur is produced as a byproduct of removing sulfur-containing contaminants from natural gas and petroleum.. Downloahere The greatest commercial use of the element is the production o ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Sun Simiao
Sun Simiao (; died 682) was a Chinese physician and writer of the Sui and Tang dynasty. He was titled as China's King of Medicine (, Yaowang) for his significant contributions to Chinese medicine and tremendous care to his patients. Books Sun wrote two books - ''Beiji qianjin yaofang'' ("Essential Formulas for Emergencies ortha Thousand Pieces/Catty of Gold") and ''Qian Jin Yi Fang'' ("Supplement to the Formulas of a Thousand Gold Worth") - that were both milestones in the history of Chinese medicine, summarizing pre-Tang dynasty medicine. The former listed about 5300 recipes for medicines, and the latter 2000. He also put forth the “Thirteen measures to keep health”, which claimed that actions like touching hair, rolling eyes, walking, and shaking heads improved health. Apart from this, he is known for the text "On the Absolute Sincerity of Great Physicians," often called " the Chinese Hippocratic Oath," or called " Dayi Heart", which comes from the first chapter of the fi ...

Gold
Gold is a chemical element with the symbol Au (from la, aurum) and atomic number 79. This makes it one of the higher atomic number elements that occur naturally. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in a pure form. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental ( native state), as nuggets or grains, in rocks, veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides). Gold is resistant to most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), forming a soluble tetrachloroaurate anion. Gold is ...

Hematite
Hematite (), also spelled as haematite, is a common iron oxide compound with the formula, Fe2O3 and is widely found in rocks and soils. Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of . It has the same crystal structure as corundum () and ilmenite (). With this it forms a complete solid solution at temperatures above . Hematite naturally occurs in black to steel or silver-gray, brown to reddish-brown, or red colors. It is mined as an important ore mineral of iron. It is electrically conductive. Hematite varieties include ''kidney ore'', ''martite'' (pseudomorphs after magnetite), ''iron rose'' and ''specularite'' (specular hematite). While these forms vary, they all have a rust-red streak. Hematite is not only harder than pure iron, but also much more brittle. Maghemite is a polymorph of hematite (γ-) with the same chemical formula, but with a spinel structure like magnetite. Large deposits of hematite are found in ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
