Lavender (Lavandula angustifolia) has a sweet, floral aroma that is soothing and refreshing. Lavender’s aroma is great for relaxing and winding down before bedtime; add to bath or diffuse to create a calming and comforting environment. Lavender essential oil may compliment your favorite shampoos, lotions and skin care products. Because it is the most versatile of all essential oils, no home should be without it.
