“Nor be the Citron, Media’s boast unsung, Though harsh the juice, and ling’ring on the tongue. When the drug’d bowl mid witching curses brew’d Wastes the pale youth by step-dame hate pursu’d, Its powerful aid unbinds the mutter’d spell And frees the victim from the draught of hell.” Chardin, in his travels through Persia, informs us that when a Persian finds himself in a distressed situation, he has recourse to a piece of opium as large as the thumb, and that immediately afterwards he drinks a glassful of vinegar; by which he is thrown into a fit of laughter, terminating in convulsions and death. With regard to the use of _Antidotes_, it has been already stated how little they are to be depended upon; in certain cases, however, we are bound to acknowledge their power, but they should be very rarely trusted, unless subsequent to, or in conjunction with, the operation of an emetic; in many cases the effects of this latter remedy may be promoted by the ingestion of liquids holding the particular antidote in solution, a practice which offers the double advantage of accelerating the elimination of the poison, and at the same time of decomposing any which may remain. Orfila has fully established the fact of _Albumen_ being a counter-poison to _Corrosive Sublimate_; vomiting may therefore be very judiciously promoted in cases of such poisoning by water holding the white of egg in solution; with equal effect, where _Verdegris_ has been swallowed, sugared water may be used as a diluent to encourage emesis; and _Muriate of Soda_ in solution will be found the most efficient antidote to _Nitrate of Silver_; and _Sulphate of Magnesia_ to _Acetate of Lead_. Where an emetic salt, like _Tartarized Antimony_, has been taken, copious dilution with common water will in general so provoke vomiting, as to render it its own antidote; but it may be useful to remember, that the _Infusion of Galls_, and according to Berthollet, the _Decoctions of Bark_, at the temperature of from 30° to 40° _Fah._ have the power of decomposing it; while Orfila considers milk the most efficient counter-poison to the _Sulphate of Zinc_.
