Since emu oil penetrates so well does it take everything with it including unwanted toxic substances?
You do not want to mix emu oil with something that you know may be toxic such as applying it after you have been exposed to poison oak or poison ivy. If you are exposed to something toxic sometime after you have applied emu oil there is no hazard related to the oil because the oil has already penetrated. So, as rule, it is best to apply emu oil to clean skin whenever possible. Use care when when mixing emu oil with essential oils for topical application.
