I always keep EO's in the house and use them for lots of different things. I scent my house cleaning products, lotions and bath salts with them so I want them to be pure therapeutic grade and these are working great. The blend right in and make the lotions smell heavenly and a few drops added to my white vinegar mop water makes the entire house smell great. This is a great starter set and would make a great gift. It comes with 10mm bottles of lavender, tea tree, eucalyptus, sweet orange, lemon grass and peppermint. Great for aromatherapy and they all work perfectly in diffusers. The only one I haven't tried in mine is the peppermint and only because it smells to much like christmas, which is great, just a bit early for Christmas smells in my home. I love this set of oils and they can be used for so many different things everyone should have some in their home.
