Dr. John Weisberg is skilled at relieving the nervous system of the stress of vertebral subluxation. The body is a self healing, self regulating and self adapting organism. The nervous system is the master control system of the body. there is nothing within the realm of the human experience that does not influence the nervous system. Therefore, if there is an interference in the nervous system, there must be interference in the body’ ability to adapt, heal, and function.
