I bought German Chamomile from here ~2 years ago, when I did not know much about essential oils.
When I get a chance to study more about Aromatherapy this year, suspected the oil is not pure.
I put this oil in my diffuser two weeks ago and the oil sinks down to the bottom and left a nasty blue greasy residue in my diffuser. When I saw that, I suspected the oil had been adulterated. I immediately bought a bottle of German Chamomile oil from another vendor specializing in high quality essential oils and the oil I put in the diffuser does not leave any residue at all.
If you are looking for German Chamomile for its therapeutic value, you most likely will be better off getting it somewhere else

Hi Helen! I'm sorry you were disappointed in this product though I can assure you that our Chamomile, German, Blue Essential Oil is 100% pure and unadulterated, as are all of our essential oils. The only exception being our Ylang Ylang III Essential Oil which is 80% pure and 20% nature identical oils to boost the scent which is noted for transparency right on our product page. Though, this essential oil very likely would leave a blue residue in a diffuser as it is blue in color. We usually recommend adding a lightweight carrier oil to any fragrance or essential oils you use in a warmer as they are not cut with any carriers.
