I use mostly auracacia, I like the quality but they're also the easiest to find in my area. I was recently introduced to doTERRA and I'm blown away at the quality of these oils. I hope to fill my collection with their oils but it will take a while because they're quite pricey (but worth it). I use a whole array of oils in my practice. It really depends on the client. I use German chamomile and rose on a lot of women, especially women entering menopause. I use camphor and frankincense a lot on men. I also work at a university and work on a lot of young clients. I like to use bergamot and other citrus oils on the younger women. I avoid any invigorating or energizing oils unless its at the very end of a session.
