The correct method for acupuncture at the Fengchi point

The Fengchi (GB20) acupoint is located at the back of the head, where wind pathogens tend to accumulate. Acupuncture at the Fengchi point helps unblock meridians, activate collaterals, regulate qi and blood, dispel wind, and resolve exterior syndromes. It can also help prevent colds. Below are the correct methods for needling the Fengchi acupoint:

1. The patient should sit upright or lie down supine. The Fengchi point lies in the angle formed between the posterior border of the sternocleidomastoid muscle and the upper nuchal line at the junction of the neck and skull.

2. Disinfect the local skin area with an alcohol swab first, then sterilize the needle using alcohol.

3. Insert the needle into the Fengchi point to a depth of 0.3–1.0 cun, and leave it in place for 20 minutes.

4. When removing the needle, use the left thumb and index finger to press the skin around the puncture site. With the right hand, gently twist the needle and slowly lift it to the subcutaneous layer, then quickly withdraw it and apply a dry cotton ball over the puncture site to prevent bleeding.

Note: This procedure must be performed under the guidance of a qualified physician. During needling, the needle tip should be slightly directed downward—never upward—and must not be aimed toward the opposite eye socket or zygomatic region. If performed improperly, the needle may enter the foramen magnum, potentially injuring the vertebral artery or medulla oblongata, leading to serious complications such as subarachnoid hemorrhage.
