Essential Oils are VERY THIN and enter the skin way too fast---the body responds to the invader with acid and burns as a self protection method…..
ONCE your brain learns that the essential oils are friendly and pose no threat…you stop making the acids and the problems al go away..
I have seen people eat extremely hot peppers with pleasure, just for the fact they ate them as children---no one told their brain it was bad……….
after handling essential oils for 20+ years, the only place they bother me is my eyes-----when i rub my eyes with my fingers---that is when I remember I got some essential oils on my fingers earlier in the day and it did not 100% wash off.
Pure essential oil of cayenne is the ultimate----20 years ago i use to call it bee sting---because 1/10th of 1 drop would burn my skin for hours……..today, 20 years later, it does not bother my skin at all---other than my eyes.
Same with pure oregano, in the early years the smell and burn was super strong---now I can't smell it and it has no burn at all---except your eyes---never get spices in the eyes---even though I have seen old people want such essential oils in the eye spray formula and they tell me that gives their eyes the enema….for me, i like my eyes and protect them.
