  • Cyperus rotundus is a species of sedge (Cyperaceae) native to Africa, southern and central Europe, and southern Asia. Sedges (Cyperaceae) are a family of monocot flowering plants. Cyperus rotundus is a common lawn weed.
  • Cyperus rotundus has been used extensively in time-honored Asian therapies, especially Indian (Ayurvedic), Chinese, and Japanese (Kampo) traditions, to treat a wide variety of ailments, including bacterial infections, inflammation, and pain.
  • The nutritional and pharmacological components of purple nutsedge are located in the tubers. Antioxidant, antimicrobial, diabetic, and weight control activities occupy current research interests.
  • At this time, there is a lack of high-quality human trials supporting the efficacy of Cyperus rotundus for any indication.
