One of Schuessler's so-called tissue remedies, not well understood as yet, but acting much along the line of Hepar sulphur, so far as we do know. I once had a case in which there was great pain in the region of the kidneys for a day and night. Then there was a great discharge of pus in the urine, which continued several days and weakened the patient very fast. A Chicago specialist had examined the urine a short time before, and had pronounced the case Bright's disease. I finally prescribed Calcarea sulphurica l2th and under its action she immediately improved and made a very rapid and permanent recovery. Since then I have found it a good remedy in profuse suppurations in different kinds of cases. This is all I know about the remedy.
