oilous

Gerarde draws the English variety as "Pinguicula sive Sanicula Eboracensis, -- Butterwoort, or Yorkshire Sanicle;" and he adds: "The husbandmen's wives of Yorkshire do use to anoint the dugs of their kine with the fat and oilous juice of the herb Butterwort when they be bitten of any venomous worm, or chapped, rifted and hurt by any other means."
