Magnetitum (Magnetite).
Pin Yin Name: Cí Shí.
English Name: Magnetite.
Latin Name: Magnetitum.
Property and flavor: cold, salty.
Brief introduction: The herb Magnetitum is the magnetic iron ore composed mainly of ferriferous oxide (Fe3O4), used as a settling tranquilizer and antiasthmatic for the treatment of tinnitus, palpitation, insomnia, epilepsy, and mania, and also used for relieving asthma. The herb is commonly known as Magnetitum, Magnetite, Cí Shí.
Mineral source: Common herbal classics and other famous herbal classics defined the herb Magnetitum (Magnetite) as the magnetic iron ore composed mainly of ferriferous oxide (Fe3O4). This commonly used mineral is introduced:
Magnetite.
Mineral Description: Magnetite: the crystalline structure of Magnetite is an equiaxed crystal system. The crystal is octahedron, granatohedron (rhombic dodecahedron), or coarse to fine granular and lumpy aggregation, the crystal surface often has parallel stripes. The color is iron black, the surface is oxidized or hydrated to reddish black, and brown-black; those have serious wind abrasion, attached with velamen of hydrohematite and ferrohydrite. The stripes are black; opaque (non-transparent); It has semimetallic luster. No cleavage, fracture surface is uneven, conchoidal, or jagged. Its hardness value is 5.5~6.5. The texture of the mineral is crisp, relative density (specific gravity) is 4.9~5.2. It has a strong ferromagnetism. It is found in many magmatic and metamorphic rocks; Beach sand is also common.
Magnetite is formed from various endogenetic geological process, that coexist with many kinds of iron-magnesium silicate minerals and rock quartz oxide, the weather resistance of the former is not as strong as magnetite and easily generate small holes from wind abrasion.
Mineral Distribution: Magnetite is mainly produced in the north, the lower reaches of the Yangtze River, and other areas of China. It is also available in other areas of the world, North America, Brazil, and Australia.
Characters of herbs: The mineral is a lumpy aggregation, which is irregularly lumpy or slightly square, mostly has edges and corners, not of uniform size. The surface is iron black, gray-black, or brown, with black streak flaws. It is opaque (non-transparent), with a semimetallic luster. The surface is not smooth, coarse, and rough. It is heavy, the texture is hard and firm, difficult to smash, and the broken surface is irregular and uneven. It has magnetic properties, there is an earthy smell and a mild taste. The herb of a better grade is iron black, glossy, has a strong iron absorption ability, and fewer impurities.
Pharmacological actions: ①.sedative, anti-convulsive effect; ②.blood tonic effect on iron deficiency anemia; ③.anti-inflammatory; ④.analgesic effect; ⑤.promote coagulation, etc.
Medicinal efficacy: Relieving convulsion, calm the nerves (relieve uneasiness of mind and body tranquilization), calm the liver and suppress yang (suppressing hyperactive liver and subsiding yang), suppressing hyper-yang to enhance respiration, improving hearing and improving eyesight (improving acuity of vision), promoting inspiration to relieve asthma. It is indicated for palpitation, insomnia (agrypnia, lose sleep), dizziness, dazzled, blurred vision (dim eyesight), tinnitus and deafness (ringing in the ears, deafness), kidney deficiency and asthma, deficiency and asthma, convulsive epilepsy, palpitation, etc.
