When my daughter was here she was telling me about them said I first she didn't think anything like that would work .Well anyway one day at work she got a horrible headache, well headaches and 28 kindergarten children just don't do well together so anyway she said something and a teacher friend put some oil on her and her headache disappeared. One of her student mothers wanted to put certain oils and a diffuser in her room . Fyi for all those thinking about applecider vinegar use with caution I got sick from using it as a diet tool
