CO 10: SHOUSANLI (Arm's Three Measure)
Two cun below CO 11. On the radial aspect of the radius, in the extensor carpi radialis brevis and longus muscles.
Will paralyse the arm, and in some cases will stop the heart. Causes a shock wave to rise up the arm into the upper body. Will cause knock out if struck hard enough. Usually used with ST 9 for a deathblow! This point will affect the whole CO meridian, especially around the arm, neck and face, hence the fact that ST 9 works really well with this point. When struck slightly upwards, the lower body will lose Qi with nausea. We have had several martial artists who have received a wack on CO 10 go down and turn slightly green. When struck slightly downwards (down the forearm towards the fingers), the bowels may work on the spot! When struck straight in, the lower abdomen will go into spasm, the arm becomes paralysed and there may be residual diarrhoea for a number of days.
