The source of this remedy is arsenic trioxides, also known as Arsenicum album. At one time arsenic was used to treat syphilis, anthrax, yaws and other diseases, and also widely used in manufacturing processes. It causes weakness, loss of appetite, vomiting, heaviness and discomfort in the stomach, diarrhoea, neuritis, a runny nose, skin eruptions, pigmentation of the skin, and eczema.
Those who benefit most from Arsenicum are deeply insecure and have an almost insatiable need for comfort and consolation. Arsenicum children are highly strung and delicate, with fine skin and hair; although mentally and physically agile, and often precocious, they get pushed around at school. Arsenicum adults have an anxious, frightened appearance and look as if they are wasting away. Because of their fundamental insecurity, any complaints they have tend to recur.
