As its name, “Three Leg Intersection” suggests, San Yin Jiao or SP6 is said to be the meeting point of the 3 Yin (or medial) channels of the leg. One can think of these three channels as separate rivers that cooperate and cross at various points, and SP6 is the key junction where their mutual power is maximized. This is awesome because it often allows us to effectively move Qi (vital energy) and Blood up the entire inner aspect of the leg with just one point. Perhaps it’s my family’s roots in landscape irrigation, but I like to think of SP6 as a major valve in a complex drip irrigation system. When we “open this valve” with a needle, it allows a rush of water to flood the system, which can moisten anything dry and brittle, and also slowly adds an upright sturdiness to anything that has been wilting.
Because these three vital channels run directly through the groin and into the abdomen, it’s no wonder SP6 is a potent point for conditions affecting these areas. It is famously used for helping with digestive and reproductive complaints, and it’s fantastic for emotional balance. I feel the inner sturdiness SP6 provides helps one find the strength to take the next deliberate step toward whatever change they are craving. While it’s not often highlighted, the stabilizing energy evoked by SP6 is also wonderful for many physical complaints. These days, I often include this point in treatments for back, leg, ankle, and hip pain, or for neuropathy in the foot. Not only does it provide a supportive, upright energy to align the body, but the three channels it influences together also have a profound effect on blood, bone, muscle, and tendons, which are all critical components of comfortable mobility. And truly, the fact that this point can also help calm the emotional stress that comes along with chronic physical discomfort is just the icing on the cake.
You might be thinking, “WOW, SP6 really does it all. Do we even need any other points?” My answer is a definite yes! SP6 is a real powerhouse, but it lacks a bit in refinement. To return to my drip irrigation analogy: Once the main valve has been opened, you still need to check the rest of your system for leaks, clogs, or areas that need more specific focus, making adjustments so that the entire system is humming along nicely.
