rose is a good example of this scenario. According to Shirley Price, in Aromatherapy Workbook, there are over 200 plants that produce an essential oil. However, there are actually only 21 plant families which produce enough essential oil, free from toxicity, that are safe to use for pure aromatherapy work.
If you have access to The Illustrated Encyclopedia of Essential Oils, by Julia Lawless, you will see that Lawless profiles over 160 essential oils. However, if you read the descriptions of each essential oil carefully you will further see that some essential oils do not have a use in aromatherapy. Many are used in the fragrance and perfumery industry, where the purity and healing powers are not as vital to use - and many more still can be extremely toxic in any situation.
So, the answer to the question, "Can you use all essential oils produced by fragrant plants in aromatherapy?" is no. Although many essential oils have many therapeutic properties that can be used in aromatherapy, there are those that are best avoided too - for several reasons :)
