SP 21 Acupuncture Point Applications and Theory

The acupuncture point "SP 21" , 大包, is represented by "Dabao" in pinyin and "Great Embracement" in english and may be found:

On lateral side of the chest and on the mid-axillary line in the 6th inter-costal space. (or) 6 cun below the axilla midway between the axilla and the free end of the 11th rib on mid axillary.


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

  • Mentioned classically that when this point is deficient, all the joints are flaccid, and when excess, pain all over the body.
  • Pain of the thoracic region.
  • Descends lung qi - cough, chest oppression, shortness of breath.


Sp 21 has the following theoretical associations which serve as important guideposts in designing an effective treatment protocol:

  • Grand Luo-Connecting Point - connects all Luo channels

A single acupuncture point is not commonly thought of as an empirical way to influence a TCM diagnostic pattern. SP21, however, is a strong candidate to be incorporated into an acupuncture protocol for patients who exhibit: Lung Rebellious Qi

SP 21 may potentially be used, in coordination with a well designed acupuncture treatment protocol, to influence the following conditions: Asthma, Chest Pain and/or Cough

While not necessarily valid clinically, GB 22 (Local Point.), GB 23 (Local Point. The Great Compendium indicates GB 23…), KD 22 (Local Point, generally useful for cough, chest te…) and LV 14 (Strong effect on the middle and upper warmers - s…) are nearby.
