Acupoints reside along more than a dozen of major meridians. There are 12 pairs of regular meridians that are systematically distributed over both sides of the body, and two major extra meridians running along the midlines of the abdomen and back. Along these meridians more than three hundred acupoints are identified, each having its own therapeutic action. For example, the point Hegu (LI 4), located between the first and second metacarpal bones, can reduce pain in the head and mouth. The point Shenmen (HT 7), located on the medial end of the transverse crease of the wrist, can induce tranquilization.
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.
Treatment protocols, frequency and duration are a matter of professional judgment of the practitioner, in consultation with the patient. A common course of treatment may initially involve between ten and fifteen treatments spaced at approximately weekly intervals, and spread out to monthly later in a program.
A professional practitioner will always warn the patient of the possibility of exacerbation at the start of a course of treatment. The patients may find that in the short term after treatment, the symptoms may in fact get worse before an improvement sets in. This is a quite common feature of acupuncture treatment.
Patients should inquire about types of needles used prior to treatment. Most practitioners now use pre-packed and sterilized disposable needles that are only once. If re-useable needles are being used patients should ask to see the sterilization procedures that the practitioner adopts.
The effectiveness of an acupuncture treatment is strongly dependent upon an accurate Chinese medical diagnosis. The needling skills and techniques of the practitioner will also influence greatly the effectiveness of the outcome. Acupuncture can be remarkably effective in many conditions, but in the West, patients often use acupuncture as the last option for their long-term chronic problems. Therefore we sometimes see the treatment as slow and in some cases of marginal benefit. With the gradual establishment of acupuncture as the treatment of choice for many people, the effectiveness of the approach with acute as well as with more chronic conditions is being recognized.
Acupuncture is often conducted in combination with Moxibustion. Moxibustion is the process where moxa sticks, made of dry moxa leaves (Artemisia vulgaris) is ignited and held about an inch above the patients’s skin over specific acupuncture points. Moxa is available in a loose form that can be used for making moxa cones. Alternatively, moxa is packed and rolled in a long stick like a large cigar, about 15-20 cm long and about 1-2 cm in diameter. The purpose of this process is to warm the qi and blood in the channels. Moxibustion is most commonly used when there is the requirement to expel cold and damp or to tonify the qi and blood. A single treatment of moxibustion usually lasts 10-15 minutes. Needle-warming moxibustion combines needling and moxibustion by attaching a moxa stub (about 2 cm long) to an inserted needle. This method enhances the effects of needling and is often used to treat chronic rheumatism and rheumatoid arthritis.
