A grasslike perennial herb that can grow to 15-150 cm in height and grows in bunches with the leaves wrapped around and extending from a small stem at ground level. The leaves are 30-100 cm long and 2-6 mm wide, dull olive green with toothed edges. The slightly fragrant white flowers emerge from a tall stalk that bolts from the base.
A poultice of the chewed root has been applied to wounds. A decoction of the grated root has been used as a wash on bleeding wounds, sprains and broken limbs. The washed roots have been rubbed to make a lather and then used to wash sore eyes.
