Anti-diarrheal properties of nut grass
As per a study published in the 2010 issue of “Journal of Ayurveda and Integrative Medicine”, nut grass may be helpful in inhibiting diarrhea in some people. For the study, diarrhea was induced in mice by giving castor oil. Researchers found that when mice were treated with nut grass, it caused inhibition of diarrhea by about 46 percent.
Nut grass is good for the digestive system
The rhizomes of nut grass have been used in traditional folk medicines in many Asian countries for the treatment of diarrhea, dysentery, intestinal parasites, indigestion, bowel disorders and other stomach problems. The chemical constituents present in this plant make it an effective remedy for combating indigestion. Nut grass contains many enzymes and active compounds which that help in stimulating various biochemical reactions that helps in promoting digestion.
Anti-inflammatory activity of nut grass
Studies reveal that the alcoholic extract of nut grass possess anti-inflammatory activity that is effective against carrageenan (an indigestible polysaccharide extracted from red algae, which is commonly used in food as a thickening or stabilizing agent) induced oedema (water retention). It was also found to be effective against formaldehyde induced arthritis in albino rats. The triterpenoid that was obtained by chromatographic separation from petroleum ether extract of nut grass rhizomes also showed very high and powerful anti-inflammatory activity. The anti-inflammatory effects of nut grass make it a potential remedy for the treatment of inflammatory diseases.
Analgesic activity of nut grass
According to studies, the essential oil and petroleum ether extract of nut grass possess strong analgesic properties and hence can be used to relieve pain.
Antipyretic properties of nut grass
Nut grass has been known to be beneficial for reducing fever and body temperature. In one study, the alcoholic extract of Cyperus rotundus was found to exhibit significantly high antipyretic activity against fever or pyrexia in albino rats.
Anticonvulsant activity of nut grass
Another medical benefit of nut grass is its ability to control epileptic seizures or convulsions. It was found that pretreatment with the ethanolic extract of nut grass offered considerable protection against convulsions (strychnine and leptazol-induced) in mice. Studies suggest that the flavonoids found in the ethanol extract may be responsible for the anticonvulsant activity and that this extract may be used to develop medicines for the treatment of epilepsy.
Nut grass can act as a tranquilizer
Nut grass also possesses sedative and tranquilizing properties. Various animal studies showed that the ethanolic extract of nut grass exhibited powerful tranquilizing activity. It was able to reduce the spontaneous motor activity, potentiate the effect of pentobarbital in inducing narcosis, derange the motor coordination and stop the conditioned avoidance response.
Antispastic activity of nut grass
Nut grass is found to have a relaxant action on smooth muscles. Studies on rabbits show that the ethanolic extract of this plant was capable of producing relaxation of the ileum and also produced spasmolytic effect against chemical induced contractions.
Antiemetic action of nut grass
Nut grass is found to be effective against vomiting and nausea as it shows antiemetic properties. The ethanolic extract of nut grass was found to prevent apomorphine induced vomiting in dogs.

Nut grass may lower cholesterol
The effect of alcoholic extracts of nut grass on the serum lipid profile of rats was studied. Hyperlipidaemia (high plasma levels of triglycerides and cholesterol) was induced in these animals by feeding them a high fat diet. Treatment with the nut grass extracts showed significant reduction in the total cholesterol, LDL (bad cholesterol) and triglyceride levels. These results suggest that the bioactive compounds found in Cyperus rotundus have the ability to lower cholesterol.
Nut grass protects the liver
Studies conducted on rats indicates that the ethyl acetate extract given to rats with induced liver damage (oral dose of 100 mg/kg) showed an important protective effect on the liver by lowering serum levels of total bilirubin and enzymes like glutamic oxaloacetic transaminase, glutamic pyruvic transaminase, and alkaline phosphatase.
Nut grass shows anti-obesity effects
Nut grass preparations (powder in fine suspension, alcoholic and aqueous extracts) were found to exhibit lipolytic action. Animal studies showed that it helped in mobilizing the fat from the adipose tissues, which in turn helped in reducing obesity. In another study, 30 people with obesity were administered powdered tuber of nut grass for 90 days. The results showed considerable reduction in weight along with a lowering in the levels of serum cholesterol and triglyceride.
Antioxidant activity of nut grass
Nut grass contains many active chemical constituents like phenolics and flavonoids that possess strong antioxidant properties. Studies suggest that the alcohol extracts of this plant exhibit high levels of antioxidant activity. These studies indicate that nut grass can be used as a potential source of natural antioxidant that could be beneficial in slowing down the aging process and also in preventing many degenerative diseases caused by oxidative stress.
Nut grass shows anti-diabetic properties
Extracts of nut grass have been found to cause significant lowering of blood sugar levels in diabetes induced rats. According to scientists, the anti-diabetic properties of this plant can be attributed to the presence of high levels of antioxidants in it.
Nut grass and anti-microbial activity
The extracts on nut grass were found to exhibit anti-microbial activity against bacteria and fungi. The oil of this plant showed a significant activity against gram-positive bacteria Enterococus faecalis and Staphylococcus aureus. According to another study nut grass showed inhibitory activity against Salmonella enteritidis, Enterococcus faecalis and Staphylococcus aureus. Eating the tuber of nut grass is believed to kill the bacteria Streptococcus mutans, which is responsible for tooth decay and the formation of dental plaque and dental caries.The essential oils of nut grass were also found to have anti-candida activity.
In spite of the fact that nut grass is a notorious wee
