title: [Exploration on new role of ancient perilous but key acupoint of renying (ST 9)].
abstract: The specific functions, stimulating methods and ranges of clinical application of Renying (ST 9) are explored. Because Renying (ST 9) is located in the neck which is a dangerous area, it is perilous if the acupoint is stimulated, so it is mostly forbidden in the past dynasties. In recent years, the main stimulating methods for Renying (ST 9) include acupuncture and press. The keys of acupuncture are to apply correct technique of needle insertion and control the depth and direction of needle. The keys of press are focused on strength and time of press. Renying (ST 9) is effective for vertigo, palpitation, asthma, hemiplegia, aphasia, hysteria, acute attack of pain, hyperplasia of mammary, continuous hiccup, disorder of throat and so on. As long as the acupoint location is accurate, manipulation is careful and stimulating method is correct, not only the safety could be guaranteed, but also the function can be well-played in clinical application.
