constipation: 2 to 6 gms of dried material in a standard cup of water,
boil to concentration and drink.
· Skin diseases: Wash the diseased portion with the hot decoction.
· Chest pains caused by deterred blood flow of blood and energy
circulation: boil to decoction 4 to 9 gms of dried drug preparation
together with 4 gms of Citrus (dalanghita, kahel, suha, kalamansi, etc.)
and drink.

Studies
•
Antidiabetic / Antioxidant: Antidiabetic
activity of hydro-ethanolic extract of Cyperus rotundus in alloxan induced
diabetes in rats: Extract study of CR significantly lowered the
blood glucose levels and showed antioxidant activity and radical scavenging
in vitro.
• Cytoprotective:
Cytoprotective effects of Cyperus rotundus against ethanol induced gastric
ulceration in rats: Study suggests cytoprotective action is due to inhibition
of gastric motility and endogenous prostaglandins.
• Wound healing:
Extract showed effects in wound healing parameters: contracting ability,
wound closure time and tensile strength.
• Stress-Reducing Effects:
Physiological EffectsEffects of herbal mixture with Cyperus rotundus
L. on blood pressure, norepinephrine, cortisol and psychological variables
in healthy medical students under examination: Herbal mixture that included
CR seems to help reduce stress-related physiological and psychological
symptoms.
• Anti-Hypertensive:
Aqueous extract of C rotundus showed a hypotensive effect in rats probably acting both centrally and peripherally altering the peripheral resistance and cardiac mechanics. Phytochemical screening yielded tannins, saponins, carbohydrates and the absence of alkaloids, proteins and sterols.
• Antimicrobial Activity: Study showed antimicrobial activity against K pneumonia, A niger and S aureus.
• Mosquito Repellent: C rotundus extract was screened for repellent activity against mosquite vector Anopheles culicifacies, A stephensi, Culex quinquefasciatus. Study showed the tuber extracts to be more effective for repellency of all the mosquito verctors even at low dose. The extract can be applied as an effective personal protective measure against mosquito bites.
• 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.
• 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.
• 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.
• 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-.
• Gastroprotective: Study results indicate that CR extracts have gastroprotective effect against acute mucosal lesons induced by ischemia/reperfusion.
• Antimutagenicity: Study shows the oil of CR does not seem genotoxic. The oil exhibited effects against both direct and indirect mutagens.
