Essential plant oils work medicinally so they MUST meet certain therapeutic standards guaranteeing their origin, exact botanical species, producing organ, and the biochemical specificity.
In the USA there are NO Federal Agency that Certify or Inspect or License Essential Oil Importers or Essential Oil Companies. You must be very careful where you purchase your oils. Some companies have trade marked the term Therapeutic Grade Certified but that means absolutely nothing so do not be fooled. It is just a marketing scam!
As of today there are NO licensing or inspecting agency with standards or guidelines in the essential oil market in the USA.
I wrote an article about the lethal Super-bug epidemic which you can readhere. In this article I mentioned two essential oils that kill the MRSA infection. (Methicillin-Resistant Staphylococcus Aureus Infection) as well as a host of other infections.
MRSA which was once confined to hospitals now is spreading rapidly among health clubs, schools and other community facilities. Research has shown that essential oils kills the MRSA infection that kills up to 20,000 Americans each year.
This research was in fact presented at a medical conference. Eucalyptus radiata and Melaleuca alternifolia (Tea-tree oil) clinical study proved to kill the MRSA infection and the data was presented at the Medical Conference.
I am sure this was a surprise to all the physicians who attended this medial conference! With 6 kids I always keep these two oils on hand!
