As a 100% pure essential oil, this lavender oil is concentrated. It works primarily through its soft, herbal-floral aroma to create a more settled atmosphere. You'll only need a small amount. The most common ways to use it are by adding a few drops to a diffuser or an oil burner to scent a room, or by mixing it into a base oil, such as sweet almond or jojoba oil, before adding it to bathwater. This prevents the oil from floating on the surface and potentially causing skin irritation. For a typical bath, you might add 5-10 drops of the lavender oil to a tablespoon of a base carrier oil. When creating a custom massage or body oil blend, a general starting point is to add about 6-12 drops of lavender oil per 30 ml (1 fl oz) of your chosen carrier oil, which creates a pleasant scent without being overpowering. Always do a patch test on a small area of skin first to check for sensitivity, especially if you have sensitive skin.
