Related Species
Many other species of Cyperus are used as foods or medicines. For example, in Chinese herbal medicine C. rotundus is used as a liver tonic, to counter indigestion and to promote menstruation. C. stolonifera, native to tropical regions of Asia and Australia, is thought to ease stomach pain and act as a heart stimulant. Perhaps the most famous Cyperus species of all is papyrus (C. papyrus). This plant provided fiber for the first writing paper, invented by the ancient Egyptians. Papyrus was also chewed like sugar cane, and used medicinally in eye compresses and to bandage wounds.
