Arsenicum album (Arsen. alb.) is a frequently-used homeopathic substance derived from the metallic element arsenic. The arsenic oxide in a homeopathic preparation is highly diluted, and so is considered generally safe, although rare reports 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 10, or 12C in homeopathic notation, mean that it is extremely statistically unlikely that any pill contains even a molecule of the original arsenic used. Several animal studies and one human trial have found a biological effect and a positive clinical result from homeopathic doses of arsenicum album; .

Preparations

When used in homeopathy, Arsenicum Album is prepared by separating arsenic from iron (as in arsenopyrite), cobalt, and/or nickel by baking at high temperatures. The powder is then ground and diluted with milk sugar (lactose). In the final dilution, there are normally no active molecules left (with potencies of over 12C) so there is little health risk.

This diluted arsenicum album is available at health food and drug stores in various potencies, in the form of tinctures (liquid), tablets, pellets, or as a powder.

Use in Homeopathy

According to Locke and Geddes, Arsen. alb. is one of the fifteen most important remedies in homeopathy, and is indicated for "treating" a particular "constitutional type", named after the remedy itself. In classical homeopathy, Arsen. alb. types are "tense, restless ambitious individuals" with a tendency toward hypochondriasis, pessimism and a meticulous attention to neatness and detail.

Claims of efficacy

A study on mice poisoned with arsenic then given arsenicum album was widely reported in 2003. According to the study, the mice poisoned with arsenic then given homeopathic doses of arsenicum album showed lower levels of molecules indicating liver damage. However, Andreas Gescher, a biochemical toxicologist interviewed by New Scientist, said "This kind of study uses a dilution so high there is hardly anything there... Is it really possible?" and went on to say that he was "extremely skeptical". The same group of researchers followed it up with a 2005 pilot study in Indian villagers affected by arsenic-contaminated groundwater. The authors described the results as "highly encouraging", but concluded that "More experiments... essential before recommending large-scale use".

Besides the above arsenic trials, there is a body of animal research using homeopathic doses of various toxic substances to reduce the effects of crude, toxic doses of that specific substance. A meta-analysis of 105 trials was published in Human and Experimental Toxicology. Although most of these studies were not high quality research, the studies that tended to show the most significant effects from homeopathic doses were the high quality studies. The researchers found that there were 40 high quality studies, of which 27 (67.5%) showed positive results from homeopathic doses. Of special interest were nine studies on mice which tested homeopathic doses beyond 15C that demonstrated a 40% decrease in mortality compared to mice in the control group.

A recent meta-analysis, which combines data from numerous studies, was published in the journal Lancet and compared homeopathic trials to those of conventional medicine. It concluded that the results of homeopathy were unlikely to be more than placebo effects; another, from the International Journal of Epidemiology, said that trials of homeopathy showed signs of major weakness in methodology and reporting, and were generally were less randomized and reported less on dropouts than other types of trials.
