Essential Oils The fact is that aroma therapy has been put to the test of being peer reviewed and it does comply with scientific standards. Not only that, but Grapefruit EO smells amazing. In short what an essential oil is, is the extract of what the plant used as it's natural defence mechanism, and then using it to boost ourselves. Lavender has been found largely to calm people down, yet not all, and this is where natural, organic, homeopathic, complimentary, and alternative medicine get's mislabeled and mistreated. As a law, natural medicines do not have the exact same effects on each person, thus we always start with a low dosage and keep record of the results. One person might get results from 1%, others need at least 5% to have similar results. So we can never in the natural remedy world say that "well this worked for that person, so surely it will work for me". No. We say "well I have tried this at these dosages and I have seen these results". Know for yourself instead of just following what you heard or read. Also Peppermint definitly assists with the following - anti nausea, - cooling, - opens up the sinus. The rest I am pretty sure all have the same effects, because yes they came from different plants, but they all did the same for each plant. Please send through your personal experiences and questions so we can all assist and motivate each other to start knowing for ourselves.
