Aloes Extractum. L. E. D. P. Aloes is the inspissated juice of theAloe spicata; A. socotrina ; A. perfoliata ; A. vulgaris; A. Hepa-tica, Sfc.Socotrine Aloes, originally brought from the island of Socotora, butnow chiefly imported from the East Indies and the Cape of GoodHope, is the extract of the spiked aloe, made by boiling down theexpressed juice of the leaves. It varies much in colour and quality:that from the Cape contains about two-thirds gum and one-thirdirritative and impure matters. It ought to be of a brilliantreddish-brown colour, very translucent at the fractured edges,of an aromatic and not disagreeable smell, and of a deep goldcolour when pulverized. Such aloes, however, is but rarely to beprocured.Cape Aloes, sometimes consists of the above, but appears to be com-posed for the most part of extracts from several species of aloe. Itought to be in hard masses of a glossy reddish-brown, with a tint ofpurple. It is weaker in efficacy and requires to be given in largerdoses than the other sorts.Barbadoes Aloes is procured from the Aloe vulgaris, and is drier thanthe preceding, as well as more violent in its operation. It is alsodeeper coloured, more opaque, and more disagreeable to the taste andsmell.Hepatic Aloes, or Bombay aloes, is sometimes confounded with the pre-ceding. It is of a light brown colour, somewhat like that of ananimal's liver, whence the name.Adulterations of all the sorts are but too common, the dearer sorts beingmelted down and mixed with those that are cheaper ; and often alsowith other substances, such as resin; and, to bring the colour to aproper tint, powdered charcoal, ivory-black, lamp-black, and some-times black writing-ink are added. One of the easiest modes of de-tecting these adulterations, is by dissolving a sample in boiling water,in which resin, &c. will not dissolve; but those who wish to have itgood ought to free it from impurities.Purified by reducing it to coarse powder and putting it in an earthenvessel in the proportion of tbj of the powder to Oij or Oiij of boilingwater, which is to be poured on gradually and well stirred till quitecold. Then set it aside from twelve to twenty hours, pour off theclear supernatant liquor, and reject the sediment. This is next t*> »—
