I always try to buy quality essential oil & the Tisserand brand is one I trust. Because the quality is so good you only need a few drops to add fragrance, whereas less potent oils require you to use more. I always keep lavender oil in the house. It's handy to have as a natural antiseptic for minor cuts, spots & grazes. I also use a small travel spray bottle with diluted cucumber water & several drops of lavender oil as a linen/pillow spray. It freshens bed linen & leaves it smelling pleasant. A few drops in a bath, oil burner or neat on a handkerchief can help promote a peaceful nights sleep. A good all-rounder.
