Bernard's Theriac.--Almost in our own time another _theriac_ came prominently before the public. In his younger years Claude Bernard, the French physiologist, worked in a little drug store in a country place not far from the farm on which he was born. There he found that the most called for remedy was a _theriac_. It was good for most of the ills that flesh is heir to and was bought in quantities by the old women of the neighborhood, who administered it on every occasion. The remedy was made in large quantities, but the secret of its composition in this particular pharmacy was what interested Bernard. Whenever any compound was for any reason spoiled in the drug store, the rule was, "Put that aside for the _theriac_." This much sold remedy then consisted of the most heterogeneous drugs. It was so diluted that it could do no harm, though it had quite sufficient taste and odor to make every one who took it realize that without doubt they were taking a strong medicine. The effect of the knowledge of the composition of this wonderful remedy on Claude Bernard was the best that could have been anticipated. He resolved to study the physiological effects of drugs so that they could be given scientifically, and not in the hit or miss fashion that made possible the success of the _theriac_. The custom of Bernard's country drug store, however, was not different from that of most country drug stores of the time. Unconscious psychotherapeutics we may well call it, because the main therapeutic factor was {21} suggestion, renewed as often as the mixture was taken, that the patient ought to feel better, until finally whatever symptoms were due to over-attention and to concentration of mind on feelings of discomfort were diverted. Just as soon as the inhibition exercised by this over-attention ceased its hampering effect nature completed the cure.
