Savory, 'A Companion to the Medicine Chest' 1836, p.90: “Tincture of Bark, Compound (Huxham’s) This tincture has long been in great repute, as one of the best preparations of bark; but the discovery of quinine has shewn that it is not so good as has been supposed. The dose is from one to three drachms. It is a grateful stomachic in dysopepsia."
