I started learning about oils and using the oils in my everyday life in March of 2015. and immediately started sharing with family and friends as I started seeing the benefits that the oils were bringing to me. We now have oils in every room of the house. Finding a favorite is hard but if I had to choose, I would say Cedarwood, Lavender, Citrus Fresh and Grapefruit are must for me as I use them every day. I diffuse Cedarwood and Lavender every night to help me have a restful sleep. I also drink 1.9 liters of water every day with a couple of drops of Citrus Fresh and Grapefruit not only does my water taste great but my digestive system is loving it.
