The use of Oils are dated back to biblical times. They were used to anoint, to heal, and even to unite. Personally, I use oils for my mental and spiritual state (in terms of balancing emotions) as well as for my physical state. One of my favorite oils is Lavender as it has many purposes. It is an oil that can be diffused or rubbed on directly!
Diffusing - Peace
Diffusing - Hormone Balance
Diffusing - Keep Sickness Away
