It is not by accident that all medicines are poisonous. Only that way can they be made to work. But there is also the patient’s imagination. During the war we were told that a marvellous new drug had come into use costing ten thousand pounds per dose, and it was being given to our wounded soldiers. Nearly everyone wants a drug like that. The rush was unprecedented and it still goes on, but a change is on the way. It was announced that penicillin was going to be made cheaper. As soon as it becomes cheap it will be discovered that the whole idea was a complete blunder. Then like many thousands of its predecessors, it will go into the graveyard of past medical "cures"—useless, discarded, forgotten or replaced.
