LIGNUM Rhodium, or Rosewood, in the Materia Medica; a wood, or root, chiefly brought from the Canary islands.

The taste of this wood is lightly bitterish, and somewhat pungent; its smell is very fragrant, resembling that Lignum Rhodium that of roses: long kept, it seems to lose its smell; but on cutting, or rubbing one piece against the other, it smells as well as at first. Distilled with water, it yields an odorous essential oil, in very small quantity. Rhodium is at present in esteem only upon account of its oil, which is employed as a high and agreeable perfume.
