 Neural therapy has been described as a form of holistic medicine for treating illness and chronic pain.According to Quackwatch, neural therapy is "a bizarre approach claimed to treat pain and disease by injecting local anesthetics into nerves, scars, glands, trigger points, and other tissues".The idea underlying the therapy is that "interference fields" ("Störfelder") at certain sites of the body are responsible for a type of electric energy that causes illness.
