Arsenicum

ORIGIN OF NAME Derived either from the Latin word arsenicum or the Greek word arse-nikon, both meaning a yellow pigment. It is possible that the Arabic word azzernikh was also an ancient name for arsenic. 

In the arsenicum adduct (15) the N—As bond (2.001 A) lies in the ring plane and eompares in length with that in other N - AsFj adducts both rings are completely planar and the length of the SS bond (2.077 A) is within the expected range <86ZN(B)162>. 

The so-called arsenic of the Greeks and Romans consisted of the poisonous sulfides, orpiment and sandarac, mined with heavy loss of life by slave labor (2). Both Pliny the Elder and Dioscorides were familiar with orpiment and realgar (sandarac) (70). The latter mentioned that Arsenicum and Sandaracha occur in the same mines, that sandarac has a brimstone-like odor, and that these two ores are roasted in the same manner (71). 

Those minerals which are not from mercury, and those salts which are soluble in water, as alums, chalcanthum (sulphates of iron and copper), common salt, sal petrae, and some substances insoluble in water alone, as orpiment, arsenicum, sulphur and other sulphurous minerals, result from the aqueosity of sulphurs mixed with viscous earths firmly united by a fervent heat, whence they are rendered unctuous and afterward solidified by cold. The medieval chemical philosophers generally do not devote so much attention to the fundamental composition of nonmetallic minerals, and the classification here given by Richardus as to their origin is by no means in accord with others, especi-... 

Treatment Sabadilla 200, 1000 and Arsenicum iodatum 200. Treatment continued for about 3 months with total alleviation of all the symptoms. 

Arsenicum album 199c and Kali iodide 200c reduced fruit rot of guava and mango. Cina 1000c, applied by foliar spray, reduced root-knot disease, caused by nematode parasites, of cowpea plants. The drugs augmented the natural defense response in plants and thus reduced the parasite infection. 

ARSENICUM — is the Greek Nitre, Effulgence of Metals Salt of Metals, and of Saturn Called also Artanek, or Artanech. Found in many places. It is also Luna, and our Venus. According to Gebir, it is Sulphur s companion. It is the soul, the hermaphrodite, the means whereby Sulphur and Mercury are united. It has community with both natures, and is, therefore, called Sun and Moon.

Arsenic compounds were known in antiquity, and the name is derived from the Greek arsenikon and the Latin arsenicum. Elemental arsenic may have been discovered by Albertus Magnus in 1250, but this is unclear. In was Johann Schroeder in 1649 who published two methods for producing arsenic, after isolating elemental arsenic. Arsenic was historically used in medicines and was developed as a treatment for syphilis. Its high level of toxicity led to its use as an insecticide. Since arsenic is a semimetallic element, it has properties that make it useful for modern electronics such as transistors.

ARSENICUM ALBUM (1327-53-3) Reacts, possibly violently, with acids, aluminum, aluminum chloride, chlorine trifluoride, chromic oxide, fluorine, fluorides, halogens, hydrogen fluoride, mercury, oxygen fluoride, phosphorus pentoxide, rubidium acetylide, sodium chlorate, sodium hydroxide, sulfuric acid, tannic acid, zinc, iron in solution. Contact with acids or acid mists releases deadly arsine gas.
