Back to school with aromatherapy: Every school year I add another essential oil to my arsenal of therapies I use to deal with the "sickies and ickies" that the kids pick up at school. My kids are totally healthy all summer long but once they hit the classroom it seems the germs accumulate overnight. With aromatherapy we encounter less and less sick days as the years go on. There are several lines of defense that a mother can take. It takes a combination of being proactive and reactive to get through a school year successfully.
