De website Plants for a Future zegt over de medicinale eigenschappen van G. maculatum:
The whole plant, but especially the root, is antiseptic, highly astringent, diuretic, styptic and tonic. An infusion of the whole plant, or of the roots alone, is used in the treatment of diarrhoea (especially in children and the elderly), dysentery, irritable bowel syndrome, cholera, kidney complaints, bleeding and a wide range of other ailments. It is often used in combination with other herbs. Externally, it is applied to purulent wounds, haemorrhoids, thrush, vaginal discharges and inflammations of the mouth. The plants are rich in tannin, the root containing 10 – 20%. The roots can be harvested in the autumn then dried and stored. It is best to harvest the roots as the plant comes into flower since it is then at its most active medicinally. The leaves are harvested as the plant comes into flower and are dried for later use.

Andere toepassing:
A brown dye is obtained from the flowers. The roots and the leaves are rich in tannin. Plants are suitable for ground cover when spaced about 45cm apart each way.
