ACUPUNCTURE
The practice of acupuncture and moxibustion is based on the theory of meridians. According to this theory, qi (vital energy) and blood circulate in the body through a system of channels called meridians, connecting internal organs with external organs or tissues. By stimulating certain points of the body surface reached by meridians through needling or moxibustion, the flow of qi and blood can be regulated and diseases are thus treated. These stimulation points are called acupuncture points, or acupoints.
In acupuncture clinics, the practitioner first selects appropriate acupoints along different meridians based on identified health problems. Then very fine and thin needles are inserted into these acupoints. The needles are made of stainless steel and vary in length from half an inch to 3 inches. The choice of needle is usually determined by the location of the acupoint and the effects being sought. If the point is correctly located and the required depth reached, the patient will usually experience a feeling of soreness, heaviness, numbness and distention. The manipulator will simultaneously feel that the needle is tightened.
The needles are usually left in situ for 15-30 minutes. During this time the needles may be manipulated to achieve the effect of tonifying the qi. Needle manipulations are generally involved with lifting, thrusting, twisting and rotating, according to treatment specifications for the health problem. Needling may also be activated by electrical stimulation, a procedure usually called electro-acupuncture, in which manipulations are attained through varying frequencies and voltages.
