Aromatherapy Products for Your Home
It is possible, though unusual, to have an allergic reaction to an aromatherapy product or ingredient. As with any product careful use, reading any instructions or warnings, and not going overboard are the best things you can do to avoid problems.
If a product is made of pure essential oil, people are less sensitive to it. Synthetic fragrances, however, may present more problems, as people tend to be more allergic to synthetic materials in general.
Keep track of materials or ingredients you've had past reactions to, and read labels carefully. If you develop a reaction, such as sneezing, a rash, or any type of breathing problem, discontinue use of the product and consult your doctor.
