The Chinese term for acupuncture, zhen jiu, refers to both the insertion of needles and the application oxibustion (heat treatment) at precise points (xue) on the skin in order to facilitate the flow of qi, blood and fluids in the body.
Needling techniques have been in use since ancient times, it is believed in the Iron Age stone needles were first introduced, this was superceded by silver and gold ones, which were superseded by high-quality sterlised stainless steel, disposable needles.
In Western medical terms acupuncture is thought to work by blocking pain receptors, stimulating the nervous system and the production of endorphins, and promoting blood circulation.
Although no one is certain exactly how acupuncture works, it is now widely recognised as an effective form of pain relief and the World Health Organisation has published a list of disorders that acupuncture can treat effectively, including digestive complaints, respiratory diseases, gynaecological ailments and neurological problems.
Acupuncture needles vary in length and thickness. Needle insertion is quick and normally painless. The points of insertion are located along 'meridians'. These are the pathways or energy channels and are believed to be related to the internal organs of the body.
Once the needles are inserted, various techniques are used to either sedate and disperse qi or to supply and tonify it.
Qualified acupuncturists complete training courses of three years duration and also need qualifications in the related disciplines of anatomy, pathology, physiology and diagnosis before the can belong to a professional association. It is very important that a fully qualified acupuncturist, who is a member of the relevant professional body, is consulted because at present time, any unqualified person can use the title 'acupuncturist'.
