"Gunpowder as a War Remedy" is one of the most interesting works of homeopathy ever crafted. The result of the mind of John H Clarke, his other works ranged from the social and political to the generally medical including a massive Materia Medica referred to here in this shorter booklet. The usage of tincture of gunpowder by Clarke, here, is claimed as effective for blood poisoning and skin disorders among other things. A man of his time, he refers, somewhat funnily, to germ theory as an actual theory as opposed to an observable facet of science. Written during the first World War, the remedies here prescribed were apparently used in the trenches of the era.
