I had not the slightest idea whether mustard taken to excess could produce heart disease, but I felt quite certain that in logic and common sense this terrible abuse of mustard was bound to do him a great deal of harm, and that in some way or other it might have upset the heart. I told him: “I shall have to stop your mustard.” He became frantic. “I do not mind leaving off anything your like from my diet by It must keep my mustard.” I callously said: “If you wish to commit suicide then you must commit suicide, but I can assure you the end will not be a pleasant one.”
I made some other very disagreeable remarks. He hesitatingly agreed to leave off mustard for a whole month, and in order to make sure I pointed out the danger to him and administered an oath that he would absolutely obtain form mustard for a month. That was the only prescription I gave him. After a month he wrote to me full of gratitude that he was cured, that heart was normal.
