One of my favourites for the oil burner. It’s a very fresh, uplifting smell. Great for ‘deodorising’ a room, if you’re using it as a general air freshener; also a must for me when I’m studying, as the slight sharpness (but less so than just lemon oil) is good for focus and concentration.
I like to mix it with black pepper, which I always find warm and relaxing, for the balance. Or a recent experiment: lemongrass, pine and bergamot – thought the pine would carry on that fresh, outdoors-y alert feel I wanted (for studying!), but when oodles came out of the bottle, I shoved in some bergamot to balance it out without being too ‘alert’. Was really nice.
