Abstract：The therapy of vagua nerve stimulation of auricular points for gastrointestinal diseases was pointed out after the authors combed concerning theories of the diagnosis and treatment of gastrointestinal dieases in traditional Chinese medicine (TCM) in combination with the principles of modern neuroscience. After analysis，it is believed that vagua nerve stimulation of auricular points is a percutaneous noninvasive therapy，treating diseases by electical stimulation of superficial branches of vagua nerve at auricular concha region. In addition， the physiological basis of the therapy is the control and regulation of enteric nervous system by nerve- endocrine- immunological network which is also called brain- bowel interaction. The connection of meridians and collaterals is not only the basis for the close relationship between auricular points and gastrointestinal diseases，but also the TCM theorectical basis of the development of the idea of treating bowel diseases by auricular points based on the vagua nerve stimulation of auricular points. Under the guidance of the idea of treating bowel diseases by auricular points， the vagua nerve stimulation of auricular points can be applied for the treatment of such gastrointestinal diseases as functional gastrointestinal disorders，inflammatory bowel dieases and postoperative ileus.
