A leaf decoction is used traditionally as a diuretic for the treatment of oedema, kidney and bladder ailments, kidney stones and gravel while a leaf infusion is taken orally or used as a douche or steam bath as a remedy for miscarriage or to aid expulsion of retained placenta. Preparations of this species have been used, combined with Pelargonium grossularioides and Mentha longifolia, to suppress the menses and combined with Diosma vulgaris as a diuretic. It is recorded as being an effective diuretic and diaphoretic. In the Montagu district, an infusion is taken to treat rheumatism, colds and gout.
