I am EXTREMELY particular when purchasing essential oils. I only buy pure, undiluted, ZERO additives, fillers, bases or carriers added. And therapeutic grade if possible. This one fits all the requirements! The price is right too. I use this lavender oil all the time...in my diffuser, humidifier, homemade lotion, baby balm, bath salts, healing salve, and magickal purpose blends. I love just opening the bottle and breathing deeply a few times...instant stress relief. It works very well for all of my needs! It also works FANTASTIC in a diffuser necklace for my 9yo daughter who has ADHD. The “Perfect” mix for her (or so she says, and I have seen a HUGE improvement in her calm and focus) is lavender and peppermint.
