UB 40 Acupuncture Point Applications and Theory

The acupuncture point "UB 40" , 委中, is represented by "Wei Zhong" in pinyin and "Bend Middle" in english and may be found:

Midpoint of the transverse crease of the popliteal fossa, between the tendons of biceps femoris and semitendinosis.

Of many possible clinical applications, it may be considered to influence the following issues/symptoms:

  • As the Lumbar Command Point, useful for all lumbar related issues: acute low back pain, sprain, muscle spasms, etc.
  • Main point for heat conditions such as summer heat, heatstroke and heat exhaustion.  Nightsweats in some cases from deficiency.
  • Main point for all skin related issues: itching, oozing, inflammation, eczema, etc.
  • Good local point for hip, leg a/or knee pain.
