Masterwort

Chambers's Encyclopaedia, Volume 7: Maltebrun to Pearson, p. 87

Masterwort (Peucedanum Ostruthium), a perennial herb of the natural order Umbelliferae. It is a native of the north of Europe and the north of America, and is found in moist pastures in some parts of Britain, but apparently naturalised rather than indigenous, its root having formerly been much cultivated as a potherb, and held in great repute as a stomachic, sudoric, diuretic, &c. The root has a pungent taste, causes a flow of saliva and a sensation of warmth in the mouth, and often affords relief in toothache. Astrantia major, a herb belonging to the same natural order and having similar properties, is also named Masterwort.
