Traditional acupuncture is based on ancient Chinese theories of flow of qi (a fine, essential substance which nourishes and constructs the body) through distinct channels that cover the body somewhat like the nerves and blood vessels. According to this theory, acupuncture adjusts the flow of qi, leading it to areas where it is insufficient and draining it from areas where it is stuck or over-abundant.
Is acupuncture safe?
When performed by a competently trained, licensed professional, acupuncture is safe. All registered acupuncturists today use individually packaged, sterile, disposable needles.
Does it hurt?
There is a saying in Japan that a good acupuncturist should be able to needle a sleeping cat without waking it up! You may feel a warm sensation where the needle goes in.
