In homeopathy, arsenicum album (Arsen. alb.) is a solution prepared by diluting aqueous arsenic trioxide generally until there is little or no arsenic remaining in the solution.〔(Arsenikum album )〕 It is used by homeopaths to treat a range of symptoms that include digestive disorders and, as an application of the homeopathic Law of Similars has been suggested by homeopaths as a treatment for arsenic poisoning. Since the arsenic oxide in a homeopathic preparation is normally non-existent, it is considered generally safe, although cases of arsenic poisoning from poorly prepared homeopathic treatments sold in India have been reported. When properly prepared, however, the extreme dilutions, typically to at least 1 in 1024, or 12C in homeopathic notation, mean that it is extremely statistically unlikely that any pill contains even a molecule of the original arsenic used.〔 While some small, unblinded studies have claimed an effect on reducing arsenic toxicity, they do not recommend its large-scale use, and studies of homeopathic remedies have been shown to generally have problems that prevent them from being considered unambiguous evidence.〔"The evidence of bias weakens the findings of our original meta-analysis. Since we completed our literature search in 1995, a considerable number of new homeopathy trials have been published. The fact that a number of the new high-quality trials (e.g. ()) have negative results, and a recent update of our review for the most “original” subtype of homeopathy (classical or individualized homeopathy), seem to confirm the finding that more rigorous trials have less-promising results. It seems, therefore, likely that our meta-analysis at least overestimated the effects of homeopathic treatments." Linde et al., ''Impact of Study Quality on Outcome in Placebo-Controlled Trials of Homeopathy'', J Clin Epidemiol Vol. 52, No. 7, pp. 631–636, 1999, .〕〔 〕 There is no known mechanism for how arsenicum album could remove arsenic from a body, and there is insufficient evidence for it to be considered effective medicine (for any condition) by the scientific community. ==Use in homeopathy== According to a popular homeopathy guide, arsenicum album is one of the fifteen most important remedies in homeopathy. In classical homeopathy, people are grouped by "constitutional type" named after the homeopathic remedy applied, on the argument that people with similar "body shapes and personalities" suffer from the same type of diseases. "''Arsen. alb.''" types are "tense, restless ambitious individuals" with a tendency toward hypochondriasis, pessimism, need for reassurance, and a meticulous attention to neatness and detail.〔 For homeopathic use, arsenicum album is prepared by separating arsenic from iron (as in arsenopyrite), cobalt, or nickel by baking at high temperatures. The powder is then ground and diluted with lactose. In the final dilution, statistically most pills will contain zero molecules of the original arsenic used, some might contain a single molecule. The final product is sold as tinctures (liquid), tablets, pellets, or powder. Key homeopathic uses include treating anxiety and "fear caused by insecurity", digestive disorders and mucosal inflammation, and ailments characterized symptomatically by burning pain. It was also used once for treatment of syphilis.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Arsenicum album」の詳細全文を読む スポンサード リンク
