This is an unproved remedy, but it has irritant properties like the other Ranunculaceæ. Hansen gives as indications: "Pemphigus; bullæ are surrounded by a ring, much itching. On the third day they are transformed into crusts." Cooper has used it with excellent effect in a case of uterine cancer, giving single doses of the Ø tincture at long intervals.
