Some aromatic oils come from herbal plants while most come from flower producing plants. Not only the flowers are used to produce the fragrance oils from but also the leaves, fruits, roots, stems and other parts of the plant can be used.

Some animals have odorous sacs that are used to create many different fragrance oils. These animals include specific kinds of whales, beavers, civets, deer and even bees. Bees are not the direct sources of the fragrance oils but their honeycombs are. Other organic or natural sources are lichens.

Some aromatic oils can be made from purely synthetic materials. These are cheaper alternatives to the more costly natural sources of the aromatic oils. Many of these are derived from petroleum and coal or tar.
