I absolutely love the Essential Oil Blends and Single blends. My absolute favorite oils in this kit are the Tranquility and Harmony oil. I don't normally like the scent of a few oils in both but honestly it's formulated so well that I just can't get enough . The oils are so nice too. Definitely not watered down. Thick, golden oils that truly change my sleep, cleaning routines, and bed/ clothing spray. I tried many brands of oils through the years until I found this brand.Highly recommend !
