So'rrel. n.s. [ꞅuꞃ, Saxon; sorel, French.] This plant agrees with the dock in all its characters, and only differs in having an acid taste. Miller.
Of all roots of herbs the root of sorrel goeth the farthest into the earth. It is a cold and acid herb that loveth the earth, and is not much drawn by the sun. Bacon.
Acid austere vegetables contract and strengthen fibres, as all kinds of sorrel, the virtue of which lie in acid astringent salt, a sovereign antidote against the putrescent bilious alkali. Arbuthnot on Aliments.
