About
Nutgrass (Cyperus rotundus) root powder — a traditional Ayurvedic skin-conditioning botanical with mild antioxidant effect. Mid-yellow on thin modern data.
Cyperus rotundus root (also called nut grass or nagarmotha) is a traditional Ayurvedic skin-conditioning and oil-control ingredient. The rhizome contains essential-oil sesquiterpenes (alpha-cyperone, cyperotundone) and flavonoids that contribute antioxidant and skin-conditioning effects. Listed in EU CosIng; typical cosmetic use is 0.1-2%. Long traditional topical use supports general tolerability, but peer-reviewed cosmetic toxicology is modest and the essential-oil fraction can contribute sensitising terpenes. No CIR monograph; no IARC classification.
