Acupuncture treats numerous emotional and psychiatric disorders, including neurosis, anorexia, insomnia, addiction (smoking cessation, eating disorders, and drug dependency) autism, schizophrenia and various speech disorders. Acupuncture encourages the development of diverse biochemical endorphins, which are opium-like substances that relieve the feeling of anxiety and depression, giving a person a feeling of well-being. Acupuncture can be substituted for psychotropic drugs, along with psychotherapy, to reduce obsessive compulsive behavior and phobias, etc. The effectiveness of acupuncture treatment can be further enhanced by diet and herbal medicine.
