Yellow toadflax has a long history of herbal use, it acts mainly on the liver and was once widely employed as a diuretic in the treatment of oedema. It is little used now, but undoubtedly merits investigation. The whole plant is antiphlogistic, astringent, cathartic, detergent, depurative, diuretic, hepatic, ophthalmic and purgative. It is gathered when just coming into flower and can be used fresh or dried. The plant is especially valued for its strongly laxative and diuretic activities. It is employed internally in the treatment of oedema, jaundice, liver diseases, gall bladder complaints and skin problems.
