Lately I have been watching and learning more about how essential oils work in the body.
Dr. Jim Bob and his wife Dr. Cindy Haggerton are Chiropractors in Hurst, TX and they incorporate essential oils, herbs, and other nutritional supplements into their practice. He has a series of YouTube videos and is very good at explaining to a non-medical person how the body works.
He is also pretty darned entertaining! Really - watch one and see if you don't agree - #awesomesauce
You can also do a google search or search on YouTube for Dr. Jim Bob Haggerton to find his videos.
