صَابٌ

A certain species of tree, from which, when it is pressed, there issues what resembles milk, a drop of which sometimes spirts into the eye, producing an effect like that of a flame of fire, and in some instances weakening the sight: (M, TA:) or a certain kind of bitter tree; (As, T, M, K, TA;) one of which is termed ↓ صَابَةٌ: (M, K: * [in the latter it is said that صَابٌ is the plural of صَابَةٌ; but properly speaking, the former is a coll. gen. n., and the latter is its n. un.:]) or the expressed juice of a kind of bitter tree: (S:) but according to the K, this is a mistake, though it is the saying of leading lexicologists: (TA:) or, as some say, the expressed juice of the صَبِر [or aloes]. (M.)
