Acupuncture, a technique of inserting and manipulating fine filiform needles into specific points on the body, has been found effective in curing headaches.
Recently it has been found that, even the fake procedures, in which the needles are inserted incorrectly, can be pretty effective.
According to traditional explanations, acupuncture works by tapping into "meridians" or channels which are described in classical and traditional Chinese medical texts, as pathways through which Qi (the vital energy) and "Blood" flow.
