Bruise the liquorice till it is reduced to pieces the size of a pea, enclose it in a gauze cloth, suspend it in a pint vessel, cover it with cold water, let it stand 12 hours (if in summer in a cool place), pour off the dense solution, renew the water, and again macerate and decant.

4596. Grahame's Fluid Extract of Burdock

4596.     Grahame's Fluid Extract of Burdock. Take of burdock, in No. 50 powder, 16 ounces; dilute alcohol (alcohol 9 parts, water 7 parts), a sufficient quantity. Dampen the powder with the menstruum and pack it in a suitable glass displacer; having covered the surface with a piece of muslin or perforated paper, pour on the menstruum, and continue the percolation to exhaustion, reserving l1/2 ounces of the first runnings, evaporate the remainder over a water-bath until reduced to 9 fluid ounces, to which add 4 ounces sugar and dissolve. Strain, if necessary, and add the reserved portion. The dose of the extract is one tea-spoonful, representing 80 grains of the root. Burdock is one of the best vegetable alteratives, or blood depurents, and it is believed that this fluid extract might be advantageously substituted for that of sar-saparilla, as a more efficient and reliable alterative, or at least as a valuable addition to it.
