Rose wood is the root or the wood of a thorny shrub, brought from the Canary islands in long; crooked pieces, externally of a whitish colour, internally of a deep yellow, with a reddish cast. The heaviest and the deepest coloured is the best.

When rubbed or scraped, it smells like roses. To spirit of wine it gives out all its virtue; but of this tincture nothing rises in distillation except the spirit, hardly affected with the smell or taste of the wood; water also extracts its virtues, and carries them with it in distillation; resembling the smell from damask roses. Fifty pounds weight of good wood afford one pound of essential oil, which is used as a perfume; it is weaker than the oil of roses, but of the same odour.

An agreeable cordial tincture is made by macerating Aspalathus 1264 iv. of this wood with a pint of rectified spirit of wine: from ten drops to a tea spoonful is a dose.
