I've seen posts on blogs, Pinterest and in my Facebook news feed about the cancer fighting properties of Frankincense essential oil, perhaps you have too. However, I've "listened in on" and even been part of discussions with leading experts in the field of essential oils and this is what they have to say:
"Does Frankincense oil contain boswellic acids? Yes, if it is distilled for 14-18 hours at unusually high temperatures, then you get about 1.3%. Otherwise, none."
Robert Tisserand, author of Essential Oil Safety
"It seems an insurmountable task for an oxygenated triterpene like boswellic acid (molecular weight 456) to be steam distilled by a normal process."
Robert Pappas, essential oil chemist
