I love Young Living. They are very particular about the product they put out. They don't add chemicals or toxins to their products and they test every single batch both in house and through independent testers. If even the smell is off just a little, they will not use it! They put their patrons over profits. I have seen it done. They are a bit more expensive but there aren't fillers and they are the highest quality in my opinion. They are medicinal quality, therapeutic grade.
