The book gives examples of induction methods, including what is now called the classic "Dave Elman Induction", as well as the use of hypnosis in dozens of physical and mental conditions. Since these uses are reserved today only for licensed professionals, and since licensed professionals usually shy away from or shun anything that is not considered mainstream, hypnosis is most often used today for behavior modification issues, such as weight loss or smoking cessation.
Since hypnotherapy is an adjunct form of therapy, used along with other forms of psychological or medical treatment, there are many applications. Hypnotherapy can be used to treat anxiety, phobias, substance abuse including tobacco, sexual dysfunction, undesirable spontaneous behaviors, and bad habits. It can be used to help improve sleep, learning disorders, communication, and relationship issues. Hypnotherapy can aid in pain management and help resolve medical conditions such as digestive disorders, skin issues, and gastrointestinal side effects of pregnancy and chemotherapy. It can also be used by dentists to help patients control their fears or to treat teeth grinding and other oral conditions.
