*Theory and Applications*
The extraordinary vessels run "behind" the 12 main meridians. They interconnect
with the 12 meridians and correspondingly allow for broad and deep effects within
the body. 6 of the 8 extraordinary vessels has a master and coupled point on a pair
of the main meridians. The Governing Vessel and the Conception Vessel, however,
have their own points.
*Extraordinary Vessel Pairings:*
Yin Qiao Mai [paired with] Ren Mai (Conception Vessel, CV)
Yang Qiao Mai [paired with] Du Mai (Governing Vessel, GV)
Yin Wei Mai [paired with] Chong Mai
Yang Wei Mai [paired with] Dai Mai
*Using the Points in Practice - Master & Couple Combinations:*
In general you needle the master point of the main meridian you are treating (due
to symptomology) and then you needle its coupled point.
For males it is common to needle the master point on the Left side and the coupled
point on the Right.
For women it is common to needle the master point on the Right side and the coupled
point on the Left.
