The plant today

Cyperus rotundus (coco-grass, Java grass, nut grass, purple nut sedge or purple nutsedge, red nut sedge, Khmer kravanh chruk) is a species of sedge (Cyperaceae) native to Africa, southern and central Europe (north to France and Austria), and southern Asia. The word cyperus derives from the Greek κύπερος, kyperos, and rotundus is from Latin, meaning "round". The earliest attested form of the word cyperus is the Mycenaean Greek 𐀓𐀞𐀫, ku-pa-ro, written in Linear B syllabic script.

Uses

The root possesses stimulant, diaphoretic, diuretic and emmenagogue properties. In the Philippines it is used internally for dysentery, and in India for the same purpose and as a vermifuge. It is given as a tonic in gastro-intestinal diseases, and General Hardwick has reported good results with it in cholera; as he reported only two cases, his testimony is not of much value.

The Chinese use the dry or roasted root, especially in inflammation of the viscera and uterine diseases. They also attribute to it diuretic, emmenagogue and anthelmintic properties. In Java and India they use it for gonorrhœa, and in Mauritius as a diaphoretic and astringent. In the Philippines the bruised root is applied to the face for toothache.
