i joined doTerra because I wanted to explore the use of essential oils. This oil was an extra gift that came as a promotion from a kit that I purchased. The claim for this product is that it will increase your metabolism and quell hunger pangs. I was mostly interested in the metabolic features, so I tried to use it (as instructed) as an additive to my water. I have to say, it was really awful to try and gag down. It has a strong citrus and bitter taste to it (kind of like the rinds of an orange or lemon). The quality of the products at doTerra are very good, but not enough to offset the extreme premium pricing they have. The Slim and Sassy product is one that I hear others talking about in a positive way, which is why I thought I would try it. My own experience is that they often don't result in the claims they make. Many people who use these blends for purposes like weight loss, emotional uplift, etc, seem to be trying to convince themselves that the product delivers the claim, but I have not found this to be true in my own experience yet. I absolutely use essential oils for health reasons, but I do not encourage their use, based on false promises. They are good for what they are good for - no more, no less. This one fell short for me.
