    Weizhong — Midpoint of the popliteal fossa

    In brief

    This point is traditionally used to relieve lower back and leg pain, including pain that radiates down the leg. It may also help with sensations of heat or skin problems.

    Where to find it

    Middle of the hollow behind the knee, between the long strap muscle of the thigh and the deep inner hamstring muscle

    How to stimulate it (acupressure)

    To stimulate this point, you can apply gentle to moderate pressure with your thumb or middle finger. Locate the midpoint of the hollow behind your knee. Apply steady pressure for 1 to 2 minutes. The sensation should be tolerable, such as mild pressure or localized numbness, never sharp pain. This self-massage is recommended 2 to 3 times a day, or as needed.

    Bloodletting

    This technique, performed by a trained practitioner, involves inducing a small superficial bloodletting. It is used with caution and is contraindicated for debilitated individuals.

    This point is a major point for conditions affecting the back and lumbar region.

    Effects in traditional Chinese energetics (TCM)

    This point's actions are to clear Heat (reduce sensations of heat), cool the Blood (soothe problems associated with excessive heat in the blood), relax the sinews (relieve muscle tension), activate the Luo (improve circulation in the collateral vessels), and strengthen the lumbar region (support the lower back). It is considered a He-Sea point (a point with a major action on the meridian), an Earth point (associated with the Earth element), and a Sea of Blood point (with a specific action on the Blood).

    Contraindications

    Bloodletting at this point should not be performed on people who are debilitated or have low vitality.
