The assumed predilection of the public for vegetable remedies is no doubt answerable for potassium nitrate being classed as “purely vegetable” in so many of these medicines. In the present case analysis showed the presence of potassium nitrate, alcohol, glycerine, a trace of oil of wintergreen, and vegetable extractive; there was no alkaloid or similar active principle, and the extract had little distinctive taste or character; all its properties pointed to its consisting largely of extract of taraxacum, with some other extract containing a small quantity of tannin; a careful series of comparisons with all the drugs in ordinary use which were not excluded by various tests did not identify it with any of them, and it is probable that it is obtained from some non-medicinal plant. The following formula gives an almost identical mixture: Potassium nitrate 50 grains. Oil of gaultheria ⅓ minim. Rectified spirit 5 fluid drams. Liquid extract of taraxacum 10 ” Glycerine 4 ” Water to 8 fluid ounces. This contains about 10 per cent. of pure alcohol, which is the proportion found in Warner’s Cure; in a mixture of which a tablespoonful was to be taken five or six—or, according to the handbill with it, six to eight—times a day, this proportion of alcohol is by no means negligible. In such a mixture there is no means of determining exactly the amount of liquid extract of taraxacum, especially as it is liable to vary considerably in colour and in amount of solid residue; this is by far the most expensive ingredient in the above formula, and it is probable that the amount is here over-estimated. Taking the quantity here given, the estimated cost of the drugs for one bottle of the mixture is 5¼d. VENO’S SEAWEED TONIC. The Company in Manchester which advertises Veno’s Seaweed Tonic sells it at the price of 1s. 1½d. a bottle, holding 2¾ to 3 fluid ounces.
