Aqua-acupuncture or aquapuncture is the injection of a liquid, typically Vitamin B-12, Adequan (polysulfated glycosaminoglycan or PSGAG), normal saline or homeopathic remedies, into acupuncture points. The purpose of the liquid is to put pressure on the acupuncture point, similar to the way an acupuncture needle is used. One of the main benefits to aquapuncture is the continuous stimulation or sedation of the point for several days. In general, practitioners will use aqua-acupuncture in conjunction with acupuncture on one to a few specific points that require prolonged stimulation.
