Acupuncture technique for the Neiting point

Neiting usually refers to the Neiting acupoint, one of the commonly used points on the Foot-Yangming Stomach Meridian. Acupuncture at this point is generally employed to clear and descend stomach fire and regulate gastrointestinal function. The most common acupuncture technique used at Neiting is perpendicular insertion; however, acupuncture should always be performed by trained professionals. The specific procedure is as follows:

1. Under the guidance of a physician, the patient assumes an appropriate position—either sitting upright with feet hanging down or lying supine. The physician locates the acupoint at the anterior aspect of the second metatarsophalangeal joint, in the web between the second and third toes, at the junction of the skin lines.

2. The practitioner takes a one-inch needle and disinfects it with a 2.5% iodine tincture swab. The practitioner also washes their hands thoroughly with soap and water, then wipes the fingertips with 75% alcohol swabs.

3. Holding the needle, the practitioner inserts it perpendicularly into the Neiting point. After inserting approximately 0.3–0.5 cun, the therapeutic effect is achieved by adjusting the angle, direction, frequency, force, and duration of needle manipulation (such as twirling).

4. The needle is retained for a short period. Before removal, the needle handle is gently twisted until a relaxed, smooth sensation is felt beneath the needle, after which the needle is withdrawn. A sterilized cotton ball is then applied to press and protect the acupoint.

Note: Acupuncture is contraindicated for pregnant women, individuals during menstruation, those with extreme physical debility, and patients with severe diabetes or hemorrhagic disorders.
