(see Gratia Dei). Digitalis minima; centaurioides; water hyssop, and hedge hyssop, gratiola officinalis Lin. Sp. Pl. 24. It is a low plant, with finely serrated leaves, set in pairs on the stalks without pedicles; the flowers are whitish, jointed, and surrounded with fibres; perennial; a native of the south of Europe; raised in our gardens.

The leaves have a nauseous, bitter taste, but no remarkable smell; they purge and vomit briskly, in the dose of half a drachm of the dry herb, and of a drachm infused in wine or water. A slight decoction in milk operates the most mildly; an extract made from wine is given to two scruples, or 3 i. and is said to be more efficacious than the plant itself. Cramer thinks this root similar to ipecacuanha, and equal to it in diarrhoeas and dysenteries, as well as, in the cure of intermittents, and superior to the decoction of the woods in the lues venerea. (See Raii Hist. Lewis's Materia Medica). It has been thought also a powerful diuretic and sudorific, as well as beneficial in mania, gonorrhoea, ozena, ulcers in the fauces, etc. Edinburgh Medical Commentaries; vol. v. p. 6.
