This is a fine short article on Essential Oils being accepted by the medical profession. Notice it does say oil quality matters, and you should learn how to use them from someone qualified to teach.  I use only Young Living Therapeutic Grade Oils, and they are the best. That's a fact, scientifically proven.
I also teach people how to use the oils on family and loved ones safely and effectively. Call me for more information (315) 635-2739
