Quick Summary

Cyperus rotundus (commonly known as Musta) is a traditional medicinal herb widely used in various botanical drug combinations, especially within Traditional Chinese Medicine (TCM) and Ayurvedic medicine. Current human clinical evidence mainly supports its inclusion in multi-herb formulations with potential benefits for obesity-related polycystic ovary syndrome (PCOS) and female infertility. However, evidence on the herb’s standalone effects is limited. Safety data specific to Cyperus rotundus in clinical contexts is not well detailed, with insufficient direct evidence on adverse effects, drug interactions, or contraindications when used alone.

What is it?

Cyperus rotundus, commonly called Musta, is a perennial plant belonging to the sedge family. It has been traditionally utilized in herbal medicine systems such as Ayurveda and TCM for a variety of health purposes. The herb is often included in multi-component herbal products rather than administered as a single botanical agent.

Traditional Uses

  • Used in Ayurvedic and Traditional Chinese Medicine formulations.
  • Traditionally applied for gynecological conditions including menstrual irregularities and infertility.
  • Included in herbal blends aimed at managing metabolic disorders associated with obesity.

Active Compounds

The herb contains various phytochemicals including essential oils, flavonoids, and alkaloids, though specific active compounds responsible for its effects have not been conclusively elucidated in clinical studies.

Potential Benefits with Evidence Levels

  • Obesity-related polycystic ovary syndrome (PCOS) – Low to moderate certainty: Meta-analysis of 72 randomized controlled trials (RCTs) involving 5,308 patients reported that herbal medicines containing Cyperus rotundus, combined with conventional therapy, may improve clinical efficacy rates and pregnancy outcomes. Considerable heterogeneity and publication bias were noted, calling for further rigorous trials. (PMID: 41640680)
  • Female infertility – Low certainty: Identified among key herbs in RCTs of 2,662 participants, herbal interventions including this herb were associated with increased pregnancy rates compared to placebo. However, the methodological quality was generally poor, highlighting a need for better-designed research. (PMID: 37778518)

Side Effects

No direct human clinical trial evidence has reported adverse effects solely attributed to Cyperus rotundus. Mild adverse effects reported in clinical studies generally relate to multi-herb combinations rather than the herb on its own.

Drug Interactions

There is no direct clinical evidence regarding drug interactions involving Cyperus rotundus identified in the currently reviewed literature.

Who Should Avoid It

There are no specific contraindications reported for Cyperus rotundus in clinical studies or systematic reviews. However, caution is advised for pregnant or breastfeeding women due to a lack of sufficient safety data during these periods.

Evidence Limitations

  • Most clinical data involve Cyperus rotundus as part of multi-herb formulations, limiting conclusions about its isolated effects.
  • Many studies demonstrate moderate to low certainty with potential biases including heterogeneity and publication bias.
  • Direct safety, contraindication, and drug interaction data for Cyperus rotundus are sparse or lacking.
  • Further high-quality, large-scale randomized controlled trials focusing specifically on Cyperus rotundus are needed to confirm efficacy and safety.
