Essential oils are to never be digested since essential oils are concentrated and are ideal for use as inhalation, in a bath,  or applied directly to the skin with a carrier oil. The oil will slowly go through the skin to the bloodstream which acts like a time release capsule. This does not overload the liver and vital organs. Essential are not for digesting instead consider fresh herbs or herbal tinctures for digesting. Digesting a Essential oil can overload liver cause serious damage to organs or worse cause death so please be wise and careful not do take internally. You will find that this practice is endorsed by mostly multi level  marketing companies (MLM)  which we at Aytz Chayim are not.
