I am considering using doterra oils and supplements but before I do I would love to hear from anyone who has used these...they are very costly so some input would def. be appreciated. I've heard essential oils are very good for becoming stable and healthy. That they pass through to the blood brain barrier and into the cells while other things cannot. Even a virus can't enter the cell it just grabs it's DNA and replicates itself over and over. Any comments or suggestions on this?
