Neural therapy is a form of complementary and alternative medicine in which local anesthetic is injected into certain locations of the body in an attempt to treat chronic pain and illness. Neural therapy is a form of alternative medicine in which local anesthetic is injected into certain locations of the body in an attempt to treat chronic pain and illness. There is no good evidence that the therapy works and it carries some risk; it has not been found to be of overall benefit.Neural therapy is a treatment system to relieve chronic pain and illness through the injection of local anesthetics into scars, peripheral nerves, autonomic ganglia, trigger points, glands, and other tissues. Treatment is based on normalizing the dysfunctional autonomic nervous system, which initiates or propagates many chronic ailments. Neural therapy has been used widely by European physicians for over 50 years. Theories of action relating to a dysfunctional autonomic nervous system and chronic pain or illness are discussed.Neural therapy is a specific injection technique used in the treatment of chronic pain and illness that stimulates healing of tissues and repair of autonomic nervous system dysfunction. According to Dr. Huneke, any type of pain, illness or organ dysfunction is always preceded by a disturbance in the autonomic nervous system. Neural irritation causes autonomic nervous system dysfunction and leads to a disturbance in circulation to tissues and unstable resting cellular membrane potentials. The accumulation of cellular debris, tissue congestion and neural irritation results frequently in pain as well as an overall impairment of the healing process . The goal of neural therapy is to restore the autonomic nervous system to normal physiologic function via resolving neural irritation, reducing interference fields, normalizing resting cellular membrane potential and regulating unstable electrical membranes. Neural therapy utilizes local anesthetics, known to restore membrane potentials in nerve cells, to restore stability to cellular membranes of the nervous system. The restoration of membrane potential has been shown to last days to weeks, or even years longer than the relatively short action of the local anesthetic . Once a nerve membrane has chronically lost its resting electrical potential of -80 mV and is chronically hypo- or hyper-polarized, the ion pumps of the nerve membrane become dysfunctional. Not only does the cell become electrically paralyzed, but the metabolism of the cell becomes impaired
