4 Acupuncture Points of the Twelve Primary Channels
Location
In the middle of the calf, between the two heads of the gastro-
cnemius muscle, on a line connecting ➞BL-40and ➞BL-60,
approximately 8 cun distal to ➞BL-40.
How to find
Slide along the dorsal aspect of the Achilles tendon in a superior
direction until you can feel the depression between the two bel-
lies of the gastrocnemius muscle. This will become more defined
when the patient’s muscles are flexed. Or:Spreading hands
technique (➞2.3.3): Place the little fingers on ➞BL-40(centre
of the popliteal crease) and ➞BL-60(depression between the
Achilles tendon and the highest prominence of the lateral mal-
leolus). The midpoint of this distance, where the thumbs meet,
marks the location of BL-57.
Located on the same level on the anterolateral aspect of the
lower leg are ➞ST-38(1 finger-width lateral to the tibia) and
➞ST-40(2 fingerbreadths lateral to the tibia).
Needling
Vertically or obliquely 1–1.5 cun
Actions/Indications
● Relaxes the muscles and tendons, opens the channel
● Eliminates haemorrhoids (pathway of the Bladder divergent
channel)
