Emily Dickinson Lexicon

A-CA'CIA, n.¹

in medicine, is a name given to the inspissated juice of the unripe fruit of the Mimosa Nilotica, which brought from Egypt in roundish masses, in bladders. Externally, it is of a deep brown color; internally, of a reddish or yellowish brown; of a firm consistence, but not very dry. It is a mild astringent. But most of the drug which passes under this name, is the inspissated juice of sloes. – Encyc.
