Lemongrass seems fine....just be sure it's not used on someone with sensitive skin, lemongrass is sometimes an irritant....lavender is one of the few essential oils that can be applied neat to the skin....ylangylang is a nice scent...floral, uplifting and smile inducing...teatree is a good one with antiseptic properties...basil essential oil is good for the skin and clarity of thought...
