Aura Cacia is a nationally branded Aromatherapy product provider and today has leaped dredlocked and pachouli-soaked head-first into the smartphone world with their new iPhone app. Now you can learn about the history and benefits of aromatherapy without having to worry about getting sandalwood oil all over your iPhone touch-screen.  While the app does have different factoids and bits of information regarding aromatherapy treatments and different combinations of oils, it is merely an information source and not a diagnostic tool like many other similar iPhone apps in the same arena.  Considering it is free, I guess you get what you pay for.
