Suggestion and Antimony.--This was an eminently scientific research. It brought the father of pharmacology to certain supposed discoveries which continued to occupy men's minds for centuries, yet ultimately proved to be utter misunderstandings of drug action, because suggestion played so large a role that it vitiated all the conclusions. The best known of Basil Valentine's books is the "Triumphal Chariot of Antimony," which contains many interesting scientific observations that were probably new at the time and which show their author's investigating spirit and his interest in scientific research. In spite of his scientific advances, however, Valentine was wholly mistaken with regard to antimony. He used it in various diseases, and, of course, it always produced very definite effects on the bowels. These effects the physician could easily foretell. It was for the patient a proof that the physician knew much, both about his disease and his remedies, since he could prophesy the results. After the antimony had exerted its influence the patient was much more ready to think that he must get better, and the influence of this suggestion worked strongly in all cases where the affection was not serious, and undoubtedly helped the patient's resistive vitality to throw off disease. In weak patients its physical effect was lamentable. It still further reduced vitality, and when used by thoughtless physicians must have done great harm. In spite of this, however, antimony continued to be used for centuries. Shortly {27} after the middle of the seventeenth century, when it was beginning to be neglected, antimony received a new lease of life as a consequence of its employment in a lingering illness of Louis XIV. The French king was attacked by what has since been recognized as typhoid fever. Many remedies were tried, but all in vain; the fever continued. When the fever had nearly run its course and the physicians were on the point of acknowledging that they could do nothing, and when a fatal termination seemed near, it was decided at a consultation to follow the advice of an old practitioner and use the old-fashioned remedy, antimony. Almost immediately the king began to get better. His improvement was quite naturally attributed to the last drug that he had taken, and antimony regained and held its remedial reputation for the next two centuries. Such stories have always worked wonders in producing popular faith and even professional confidence in drugs. When great personages seem to be cured by certain remedies, ordinary logic ceases to act, and the strong power of suggestion comes in to strengthen whatever remedial influence there may be.
