As noted by the Massachusetts Board of Health, the dose recommended upon the labels varies considerably, but practically all agree in suggesting that the amount of the remedy taken shall be increased as needed. A simple presentation of this subject will surely be sufficient to arouse clergymen {96} to a proper sense of their duty in this matter. Senators, judges of Supreme Courts, Congressmen, and even university professors and teachers may be so benefited by dilute whiskey, taken early and often, as to be tempted to furnish testimonials for them (for a due consideration usually), but clergymen should at least know something of the consequences of their act before committing themselves. An almost precisely similar state of affairs obtains with regard to another class of favourite popular remedies. A number of so-called blood-purifying remedies have been recommended at various times, and here, as in other things, it is surprising to find how many intelligent people lend themselves to the exploitation of the public in the interests of the proprietary vender, who cares only to sell, and cares very little what effect his remedies may produce. Most of the sarsaparillas are said to be blood purifiers. It is surprising what vogue this word "sarsaparilla" has obtained. A little more than half a century ago a German chemist and pharmacist announced that the sarsaparilla plant contained certain principles that could be extracted by boiling, and that form excellent remedies for atonic and anaemic conditions. This announcement was received by the medical profession very kindly, and immediate tests as to the efficacy of the new remedy were made. As a result of these tests, within a few years the inefficacy of sarsaparilla became very clear. It is almost entirely without effect upon the human system. In the meantime, however, the word "sarsaparilla" was one to conjure with for the popular mind, and the sarsaparilla remedies began to be manufactured. Millions have been made on them and out of the public. The only active agent as regards tonic qualities which they contain is, as we have said, alcohol. Most of them however, contain at least one other well-known drug likely to be at least as harmful as alcohol. This is iodide of potash. Very few of the so-called sarsaparillas are without a notable proportion of this strong mineral salt, as the Massachusetts Board of Health said. "With but few exceptions they contain a considerable percentage of a very active and powerful remedy, the iodide of potassium. The sale of such an article in unlimited {97} quantities by druggists, grocers, and others is censurable. More than this, the method of its sale is dishonest, since the unwary purchaser is led to believe that he is purchasing a harmless vegetable remedy, namely, sarsaparilla.
