Condurango was lauded as a cure for gastric ulcer and cancer of the stomach some years ago. Needless to say, it disappointed. It has quite a history in the camp of the homeopaths, from whom we borrowed it and returned it in a damaged condition. They say its guiding symptom is "painful crack in corner of mouth." It impresses me we have had lots of smoke for a very little fire. It is probably of some service in catarrhal gastritis, since its influence resembles hydrastis. (F.e., 15 to 60 I.)
