We talk a lot about the pros of essential oils over here. Their benefits are too many to count and if I had to choose one thing to be stuck on a desert island with, it would be my oils. Part of the power of the oils is the knowledge of when and how to use them. Too often I see oils for sale in the Vitamin Shoppe, surrounded by young women who want to see what all the hype is about. They are all the rage right now. And while, yes, they are AMAZING. They can also do terrible harm if not used properly.
