However, with the lack of better information, it is probably wise to exercise caution with oils that are considered toxic. The affects of toxicity from Essential Oils are of a longer term nature and do not manifest themselves immediately. Our bodies have the natural ability to rid itself of toxins, yet if a toxin is repeatedly brought into the body it can break down our natural systems and cause a build-up of any harmful substance. To be safe, only use toxic oils sparingly and do not use them continuously over long periods of time. Viscosity - A common term used to describe the thickness of an Essential Oil.
Water is a high viscosity liquid, as opposed to molasses, which is very low viscosity.
