What are the effects and functions of Cyperus rotundus?

In fact, we can all learn more about the effects and functions of Cyperus rotundus, so that when we encounter some problems in life, we can use them correctly to help solve them, such as it can help to have antibacterial and anti-inflammatory effects.

1. Effect on the uterus: Zhang Fachu et al. reported that 5% Cyperus rotundus fluid extract has an inhibitory effect on the isolated uterus of guinea pigs, rabbits, cats, dogs and other animals, whether pregnant or not, weakening their contraction force and reducing muscle tension. Its action properties are quite similar to those of angelica, but weaker.

2. Anti-inflammatory effect: Singh N reported that intraperitoneal injection of 100 mg/kg of Cyperus rotundus alcohol extract had a significant inhibitory effect on rat foot swelling caused by carrageenan and formaldehyde. This effect is stronger than 5-10 mg/kg hydrocortisone. Gupta MB's research has shown that its anti-inflammatory components are triterpenoids. Among them, ingredient IV-B has an anti-inflammatory effect on foot swelling caused by carrageenan, which is 8 times stronger than hydrocortisone and has a safety range 3 times larger. It also has an inhibitory effect on formaldehyde-induced foot swelling. The potency ratio between oral administration and intraperitoneal injection was 1:3, indicating that it may be only partially absorbed in the digestive tract.

3. Antibacterial effect: In vitro tests show that the volatile oil of Cyperus rotundus has an inhibitory effect on Staphylococcus aureus, but is ineffective against other bacteria. The antibacterial effect of cypermethrin I and II is stronger than that of volatile oil, and they are also effective against Shigella sonnei. Hydrogenation does not affect its antibacterial effect. Cyperus rotundus was completely ineffective. Cyperus rotundus extract also has an inhibitory effect on certain fungi.

4. Other effects: Cyperus rotundus alcohol extract has a protective effect on guinea pig bronchospasm caused by histamine spray. The prostaglandin biosynthesis inhibitor contained in Cyperus rotundus is mainly a-Cyperone.
