Ordered, used one time. I love it but I do not like it mixed with my body chemistry. Paying attention and staying on task is an important part of effective study. InTune, a proprietary blend of uplifting and earthy aromas, is delightful when used while working or studying. This combination of Amyris, Patchouli, Frankincense, Lime, Ylang Ylang, ‘Iliahi (Hawaiian Sandalwood), and Roman Chamomile essential oils is high in limonene and ά-pinene. These two main chemical compounds are calming. The aroma of Ylang Ylang essential oils is relaxing, uplifting, and harmonizing. Packaged in a convenient roller bottle, InTune fits easily into a purse or pocket and is easy to apply when needed. Smoke free home.
