The purity of the oils is the best I have tried.
The purity of the oils is the best I have ever found. You can tell by the smell of each oil and you also know that it does what it is claimed to do. I am not sure of some doterra products sold on ebay which I have purchased because of their smell. I think maybe there is away to reproduce cheaper because the low prices seem to good to be true and plus the smell is off. I can't prove this!
