Turkey rhubarb, the well-known medicinal drug, is the root of a very elegant plant (Rheum palmatum), coming to greatest perfection in Tartary.

The common rhubarb is a native of Asia; the scarlet variety has the finest flavour.

It is an apish work in such sort to juggle with Holy Scripture: it is no otherwise than if I should discourse of physic in this manner: the fever is a sickness, rhubarb is the physic.
