A friend had been using essential oils for various health conditions and had told me the great results she had when she used essential oils. My husband has allergies that are off the scale and I wanted to find a way to help him feel better and hopefully get him off of those over the counter medications and allergy shots he takes as well as hoping to help him have days that were not so miserable. I started him with the 3 oils for allergies and, needless to say, he loads the diffuser himself and I don't even have to remind him. Being the skeptic he is, that is major. I love learning about the oils and try to attend every class I can to learn everything I can about essential oils.
