Umbrella Sedge is a perennial herb, about a meter tall, arising from rhizomes and tubers. The stems are 3-sided and triangular in cross section and there is an umbrella-like tuft of long narrow leaves at the top. The leaves are yellow to green in color with a distinct ridge. The plant has red-brown flower spikelets with up to 40 individual flowers. The dried tuberous roots are collected, dried and used in traditional medicine. Nutgrass is used in hair - and skin care products. It stimulates sebaceous glands near hair roots. Also interesting is that the oil, an amber viscous liquid, extracted from this plant is used in perfumery.
Medicinal uses: The tubers are credited with astringent, diaphoretic, diuretic, dessicant, cordial and stomachic properties. A decoction of the tuber is used for washing hair, treating gonorrhea and syphilis. It is also given in diarrhea and for general weakness.
