Fluoric acid is a valuable remedy in disorders resulting from perverted nutrition, reminding us in its clinical action of Silicea, Calcarea, etc. It is useful in unhealthy, broken down con- stitutions, where there is a tendency to a destruction of tissue, especially in those who have ruined their systems by the use of intoxicating liquors, or who suffer from a syphilitico-mercurial dyscrasia. Useful in the complaints of old age, or in patients who are prematurely old from excesses and consequent perverted nutrition. In such we find a tendency to varicose veins and ulcers, bed-sores, syphilitic ulcers, exostoses, bone-pains, etc. Fluoric acid is invaluable in the treatment of diseases of the bones, particularly the long bones, especially caries, with a thin excoriating discharge ; also caries of the temporal bone, especially of the mastoid process ; also of the maxillary bones ; bone fistulae, particularly dental fistulas, with persistent bloody, salt-tasting discharges, which render the mouth foul; lachrymal fistulae; felons, especially bone felons, with violent throbbing pains, sometimes sensation of splinter under the nail. Brittleness of the nails, which crumble or have longitudinal furrows. In all bone affections and suppurative processes Fluoric acid may greatly resemble Silicea, except that in the former there is relief from cold, whereas in Silicea the patient cannot bear cold. Synovitis. Sometimes useful in ascites, in the broken down constitutions of drunkards; also with enlargement, induration and sometimes degeneration of the liver. Hydrothorax. Chronic nasal catarrh. Goitre. Syphilitic ulcerations of the throat; ozoena; otorrhea. Alopecia areata. Naevi. Old cicatrices become red and itch violently. Lupus-like tubercules. It is said that in many diseases Fluoric acid is indicated by the clinical symptom : "it seems as if she could walk forever," there being a disposition to constant and rapid motion.
