Jojoba oil is pressed from the seed of the jojoba plant that grows in Southern California, Arizona, and Northern Mexico. It is actually a liquid wax that is slightly nutty in flavor. Yes, it is edible but non-caloric since it is not absorbed. It is mainly used in cosmetics. It became popular in the 1970s as a replacement for whale oil. It is quite shelf stable because it does not have triglycerides. It is a natural fungicide and is therefore ideal as a base in products used for itchy skin.
