| Aloes is a medicinal substance used as a purgative and produced from various species of aloe, such as A. vera, vulgaris, socotrina, chinensis, and perryi. Several kinds of aloes are distinguished in commerce--Barbadoes, Socotrine, hepatic, Indian, and Cape aloes. The first two are those commonly used for medicinal purposes. Aloes is the expressed juice of the leaves of the plant. When the leaves are cut the juice flows out and is collected and evaporated. After the juice has been obtained, the leaves are sometimes boiled, to yield an inferior kind of aloes.. |
