Internal Treatment. Arsenic in the form of arsenite of sodium (Fowler’s solution) arsenious acid (Asiatic pill) or arsendiamethyl (caccodylic acid), potassium iodid, sodium salicylate, salicin, mercury, doses, do not yield startling results in most cases but nevertheless, at times, individual patients may be benefited by a short course of such physiological medication. The poverty of local symptoms may deter one from making a satisfactory pathogenetic prescription on this basis alone, but if the constitutional symptoms as well are taken into consideration in the selection of a remedy, a carefully chosen drug offers the best chance for a real cure. I have seen benefit derived from the following: Agnus cast., Arnica, Arsen., Asterias rub., Borax, Calcarea fluor, Cantharis, Carbon. acid, Colchicum, Hydrocot., Iris ver., Kal. bich., Lycop., Mangan, Mercurius vivus, Mez., Nat. arsen., Pyto., Petro., Sul., Thuja.
