The salts of Magnesia are not new to the medical profession as remedies. Especially is the one under consideration so well known in its action upon the intestinal canal that it has for a long time been "my lady's" habitual resort for sour stomach and constipated bowels. Of course, then it should become a very useful remedy for diarrha in the hands of a Homopathist, and so it is. The kind of diarrha to which it is most applicable is -"Stools green and frothy like the scum of a frog pond." All of the Magnesias are great pain producers, consequently pain relievers, and, as might be expected, the stools of Magnesia carb. are preceded by griping, doubling-up colic. So far as colic is concerned, sometimes it might be difficult to choose between Magnesia carb. and Colocynth, but the stools are not alike. Rheum comes nearest to Magnesia carb., in that both have colic before stool, sour stool and sour smell of the whole body; but with Magnesia the green stool stands first and with Rheum the sourness. The stool of Rheum is oftener dark brownish than green. Chamomilla has green stool with much pain, but the stool is watery, while Magnesia carb. is more slimy. Mercury has the slimy stool which may be green also; but with Mercury tenesmus is the leading symptom, and the mouth symptoms and sweat without relief under it are not like the other remedies. Magnesia carb. has toothache which at first sight seems to simulate that of Mercury. It comes in decayed teeth and is worse at night. There is a finer shade of difference, however, that distinguishes them. Mercury is worse from the warmth of the bed (a general characteristic of Mercury), while Magnesia carb. is worse quiet. The patient is obliged to walk about for relief. This kind of toothache is common among pregnant women, and I have often cured it. (Ratanhia.) I have used it in the 200th potency for this trouble. Have used it lower in diarrhas. I once cured a severe case of coccydynia, a case of long standing. The pains were sudden, piercing, causing the patient to almost faint away. Magnesia carb. 200th cured promptly. Lobelia inflata has extreme sensitiveness; sits leaned forward to avoid contact of even soft pillow.
