NOW Foods Lemongrass Oil is a 100% pure essential oil steam-distilled from Cymbopogon flexuosus — a tropical grass native to Asia with a fresh, citrus-herbaceous aroma distinctly different from lemon. High in citral (a mixture of geranial and neral), lemongrass oil has demonstrated antimicrobial, anti-inflammatory, and antifungal properties, and is widely used in aromatherapy for relieving muscle tension, calming stress, and creating an uplifting, refreshing atmosphere. It is also a popular addition to natural insect repellent formulations. NOW Foods' Lemongrass Oil is GC/MS tested for identity and purity. Dilute well in a carrier oil before topical application, as lemongrass can be sensitizing to skin at higher concentrations. A vibrant, versatile oil equally at home in the diffuser, massage blends, or natural household products.
