I acutally have a home business where I make custom blended therapy grade aromatherapy products. I use Dreaming Earth Botanicals for my EO's and Bases. They are really reasonably priced (IMO) and the quality is top of the line. They carry the SomaTHerapy line which are....
"professional quality, aromatherapy grade essential oils, extracted by non-toxic methods. they are always 100% pure , undiluted, unadulterated in any way. They are obtained by wild harvest and/or organic sources when avialable from sources that meet the standard for quality and effectiveness. however, many essential oils are simply not available from certified organic growers or from ecologically responsible wild harvesters."
All oils are lab tested to verify purity and authenticity.
THis is what I use to make my blends. I have never had a problem at all with quality of the product.
