Purple nutsedge


Purple nutsedge (Cyperus rotundus) is a species of sedge (Cyperaceae family) native to Africa, southern and central Europe, and southern Asia. Sedges are a family of grass-like flowering plants. Purple nutsedge is considered an invasive weed in North America and is a common lawn weed. The therapeutic components of purple nutsedge are located in the tubers (a type of underground stem), which resemble nuts in appearance (hence the name nutsedge).
Purple nutsedge has been used extensively in Asian therapies, especially Indian (Ayurvedic), Chinese, and Japanese (Kampo) traditions, to treat a wide variety of ailments, including bacterial infections, inflammation, and pain. In traditional medical systems in the Middle East, both fresh and dried forms of purple nutsedge have been used in a paste to heal skin wounds, ulcers, and sores.
Modern research on purple nutsedge has investigated its possible antioxidant, antimicrobial, antidiabetic, and weight control effects. At this time, there is a lack of high-quality human trials supporting the efficacy of purple nutsedge for any indication.
