NOW Foods Lemongrass Essential Oil 4 fl oz delivers the same 100% pure, steam-distilled Cymbopogon flexuosus as the 1 fl oz bottle in a generous economy size — ideal for those who use lemongrass daily in diffusers, body care formulations, yoga studios, or as an aromatic cleaning ingredient. High in citral (geranial + neral), lemongrass has a fresh, bright, citrus-herbaceous aroma with proven antimicrobial properties and a refreshing, uplifting effect when diffused. NOW Foods' 4 fl oz size provides outstanding value for frequent users of this versatile and popular essential oil. GC/MS tested for identity and purity. Dilute appropriately before topical application. Not for internal use.
