4.7 The Bladder Channel System – Foot taiyang(zu tai yang jing luo)
Location
1.5 cun lateral to the posterior midline, on the level of the lower
border of the spinous process of the 5th thoracic vertebra (T5).
How to find
First, locate the spinous process of C7 (➞3.4.1). From there,
count down five spinous processes to the lower border of the
spinous process of T5. Measure 1.5 cun laterally to locate BL-15
on the highest point of the paraspinal musculature. Or:With the
patient seated and their arms hanging down, the spinous process
of the T3 is generally on the level of the easily palpable medial
end of the scapular spine (➞3.4.2). From there, count down two
spinous processes in an inferior direction to the T5. Locate
BL-151.5 cun lateral to the midline.
Located on the same level are ➞Du-11(on the midline), a point
of ➞Ex-B-2 (0.5 cun lateral to the midline) and ➞BL-44
(3 cun lateral to the midline).
Needling
0.5–1 cun obliquely towards the spine. In clinical practice, this
point is often needled transversely (subcutaneously) towards the
spine. This allows the patient to lie in a supine position during
needle retention (the needles can be secured with tape). Caution:
Pneumothorax.
Actions/Indications
● Tonifies and nourishes the Heart, regulates the Heart Qi,
unbinds the chest and removes Blood stasis, calms the shen,
clears Fire, moves Qi locally and along the channel pathway:
for example, for disorders of the thoracic spine and inter-
costal region
