One of the important things to remember, especially if you are going to put the oil on the body, is to be sure that the oils that were used were from wild or organically grown plants. You have to make sure that the oil is derived from an organically grown plant if you want to have the best aromatherapy possible. So many of the aromatherapy products that are on the market are not of that quality; probably most of them. Secondly, some of them are even synthetic fragrances they are using. Another very important thing is the base that the essential oil is in. If you are going to put it on your body and you put it in a base that's non penetrating, then the oils cannot be absorbed into the body to do their job. So, if you see anything that says it has mineral oil or any kind of petroleum base, then it is not going to allow the product to really do anything; it is just going to stand on top of the skin. So very few of the products out there really will do the job; they are just using the name.
