You have to use pure oils and those are not sold at the stores. They are not regulated by the FDA, so oils on a shelf can be labeled as 100% pure with only 5% of the actual oil. The rest can be fillers. Also, check the labels. Most of them say "not for topical use". When you see that, it means it's perfume grade and that just dosn't have the healing properties the pure ones have.
I believe your service is superb and more should access it. Keep up your great work. Many many thanks to the wonderful work you do and the manner in which you help people.
