A disturbing section was the one on pets. I would definately do more research before putting anything on a cat. Cats lick their fur and not all oils can be ingested. Eucalyptus is toxic if taken internally. There have been reports of Tea Tree nearly killing cats. In addition, they recommended adding tansy to a horse’s feed to treat worms. Tansy is very toxic to horses and cows. People usually try to remove the plant from their pastures.

Last word. Do your research and don’t just use one book. More information at The Complete Book of Essential Oils and Aromatherapy
