Abstract
The physician who wishes to treat by hypnosis, asthma or any other disorder in which spasm is a characteristic sign, symptom or symbol, must, in general, be familiar with the two chief types of reflexes. The therapist must also possess a detailed knowledge of the structure of the normal functions of the organ which is the site of the spasm, and must know how these functions may be changed by the disorder when it is the result of conditioned reflexes and how they may be returned to normal by deconditioning the patient.
