Spleen 6 '
Spleen 6' is widely known as the crossing point of the Spleen, Liver and Kidney channels. One of the books we used (it's been ages ago, so I can't remember what the title was) when learning points listed three other, similar points, which it identified as crossing points of the Leg Yang channels (
Gall Bladder 39 - '
Gall Bladder 39'), Arm Yin channels (
Pericardium 5 - '
Pericardium 5'), and Arm Yang channels (
San Jiao (Triple Burner) 8 -
San Jiao (Triple Burner) 8). I haven't seen this information in other books, but the name of
San Jiao (Triple Burner) 8, at least, points to a similar overlap.
The combination of all 8 points serves to address all 24 circulating channels, and has a broad, gentle full-body-balancing kind of effect. I like to use the combination with one or two other points to add a slight focus (e.g.
Heart 7 for anxiety or pain, or
Du Mai (Governing Vessel) 20 for fatigue).
I've heard the combination called the 'Tai Ji' treatment - which, I suppose, is more or less appropriate.
