NOW Foods Eucalyptus Globulus Oil 4 fl oz is a 100% pure essential oil steam-distilled from the leaves of Eucalyptus globulus, providing the same high-1,8-cineole therapeutic oil in a larger economy size perfect for regular diffusion, aromatherapy practitioners, and natural product makers. Eucalyptus oil's characteristic refreshing camphor-like scent is both clarifying and supportive for respiratory health — making it a cold-season staple for steam inhalations and chest rubs. GC/MS tested by NOW Foods to verify identity and the correct therapeutic cineole profile. This larger format offers significant value for those who use eucalyptus oil regularly in diffusers, homemade cleaning products, or wellness preparations. Dilute in a carrier oil for topical application. Not for internal use.
