Botany
Cyperus rotundus is a slender, erect, glabrous, perennial grasslike plant, 10 to 40 centimeters high. Rhizomes or underground stems are wiry, bearing black, hard, ovoid tubers which are about 1 centimeter in diameter. Ground stems are usually solitary, distinctly 3-angled above. Leaves are 5 to 15 centimeters long, sometimes as long as the stems, about 3 millimeters wide, and narrowly linear. Umbel is simple or compound, 2 to 6 centimeters long, with 2 to 8 unequal primary rays. Spikes are dense or rather lax. Spikelets are 3 to 8, 10 to 25 millimeters long, brown, slender, with 10 to 25 florets in each spikelet, linear, and slightly compressed. Rachilla of the spikelet distinctly winged. Glumes are 2.5 to 3 millimeters long, closely or loosely imbricate. Glumes of the floret distichously arranged, the first 2 empty, the third one bisexual. Fruit is an achene, obovoid or oblong, black or granulate, 3-angled, one-seeded, covered with a scurfy bloom.

Phytochemical screening yielded tannins, saponins, carbohydrates and the absence of alkaloids, proteins and sterols.   (4)
Antimicrobial Activity: Study showed antimicrobial activity against K pneumonia, A niger and S aureus.
Mosquito Repellent / Root Tuber: C rotundus extract was screened for repellent activity against mosquito vector Anopheles culicifacies, A stephensi, Culex quinquefasciatus. Study showed the tuber extracts to be more effective for repellency of all the mosquito vectors even at low dose. The extract can be applied as an effective personal protective measure against mosquito bites. (8)
Polyphenols / Antioxidant: Study on the rhizome extract of Cyperus rotundus exhibited concentration-dependent scavenging effect on superoxide anion radicals, OH radicals, NO radicals, H2O2, metal chelating and reducing power. Results suggest CR rhizome extract can be a potential source of natural antioxidant. (9)
Anti-Obesity Effect: Study of C rotundus tubers hexane extract for 60 days induced a significant reduction in weight gain without affecting food consumption or inducing toxicity. In vitro, the extract was able to stimulate lipolysis. The effect in weight gain may be partially mediated through activation of ß3-AR. Results suggest CR tuber extract has a potential as a herbal supplement for controlling body weight. (10)
Anti-Candida Activity: Study of essential oils and ethanolic extracts of leaves and/or roots of 35 medicinal plants in Brazil were screened for anti-candidal activity. The essential oils of 13 plants, including Cyperus rotundus, showed anti-Candida activity. (12)
Anti-Inflammatory: Study showed the methanol extract of rhizomes of CR showed inhibition of NO production in a dose-dependent manner from the suppression of iNOS protein, as well as iNOS mRNA expression. Results suggest a potential for the methanol extract to be developed as an anti-inflammatory agent for diseases mediated by overproduction of NO and O2. (13).
Gastroprotective: Study results indicate that CR extracts have gastroprotective effect against acute mucosal lesions induced by ischemia/reperfusion. (14)
Antimutagenicity / Essential Oil: Study shows the oil of CR does not seem genotoxic. The oil exhibited effects against both direct and indirect mutagens.
(15)
Infectious Diarrhea / Tubers: Study evaluated the antidiarrheal activity of C. rotundus tubers decoction.

There was no toxicity in mice up to dose of 300 mg/kbw. The extracts also showed significant enhancement of lymphocyte proliferation at 1 mg/ml. The extracts yielded potent components such as flavonoids which may be potentially useful in the modulation of immune cell functions, provoking analgesic, anti-inflammatory and antioxdant effects. (35)
Ovicidal / Larvicidal / Essential Oil from Tubers: Study evaluated essential oils extracted from tubers on eggs and fourth instar larvae of Aedes albopictus. Results showed remarkable ovicidal and larvicidal activities indicated by EC50 values of <5 ppm and LC50 and LC90 values of <20 ppm. Results suggested the essential oil as a potential source of natural mosquitocidal agents. (36)
Antimalarial / Tubers: Study of C. rotundus tubers isolated patchoulenone, caryophyllene or-oxide, 10,12-peroxycalamenene and 4,7--dimethyl-l-tetralone. The antimalarial activities of these compounds are in the range of ECso 10-4-10-6 M. A novel ndoperoxide sesquiterpene, 10,12-peroxycalamenene, exhibited the strongest effect at ECso 2.33 × 106 M. (36)
Biosorption of Crystal Violet: Study evaluated the biosorption potential of two agricultural wastes, Citrillus lanatus rind and Cyperus rotundus to remove Crystal violet (CV) from aqueous solution. Results showed good sorption capactities of 46.68 and 54.24 mg/g for CV biosorption by C. lanatus rind and C. rotundus, respectively. (37)
Antiamoebic / Cytotoxicity: Study evaluated the in-vitro antiamoebic activity and cytotoxicity (MTT assay) of an ethanol extract of C. rotundus whole plant. In an in-vitro study against E. histolytica trophozoites, the extract showed 100% mortality at concentration of 500 ppm. In cytotoxicity study, the MTT assay verified the safety of the extract with an IC50 of less than 100 µg/ml. (38)
