What is it
Nut grass (Cyperus rotundus) is a sedge whose rhizome (tuber) is used in Ayurvedic and traditional Chinese medicine, where it is known as musta or nagarmotha. It is taken as a powder or extract, traditionally for digestive complaints, menstrual issues, and inflammation. Human clinical evidence is very limited, with most data from animal and laboratory studies.

traditional digestive and anti-inflammatory use
Mechanism onlyCyperus rotundus has a long traditional record for digestive and inflammatory complaints, and laboratory and animal studies report anti-inflammatory, antioxidant, and antispasmodic activity. There are essentially no rigorous human trials to confirm clinical benefit. Any claimed effects rest on preclinical mechanisms rather than demonstrated outcomes.
Bottom line: Nut grass shows anti-inflammatory and antispasmodic activity in lab and animal studies, but human benefit is unproven.
Evidence is mixed
Support is limited to preclinical data and tradition; controlled human trials are lacking.
