NOW Foods Lavender Oil 4 fl oz delivers the same 100% pure, steam-distilled Lavandula angustifolia essential oil as the 1 fl oz version in a generous economy size perfect for households that use lavender daily — in diffusers, linen sprays, bath preparations, and skin care blends. Lavender's linalool and linalyl acetate content make it the most versatile and universally beloved essential oil in aromatherapy, with research supporting its calming, sleep-promoting, and anxiety-reducing effects both aromatically and topically. NOW Foods' Lavender Oil is GC/MS tested to verify the correct composition and origin, ensuring you receive therapeutic-quality Lavandula angustifolia — not lavandin (a hybrid with a coarser aroma). At 4 fl oz, this size offers significant value for regular lavender users.
