Notes: Clinically, Yuan-Source points are of great significance in treating diseases of the internal organs. Yuan-Source points are the sites where the Yuan (Primary) qi of the Zang-Fu organs passes and stays. Puncturing the Yuan-Source points stimulates the vital energy of the regular meridians, regulates the functional activities of the internal organs, reinforces antipathogenic factors and eliminates pathogenic factors. This method of treating diseases deals principally with the root causes. The Yuan (source) point from the affected meridian is often combined with the Luo (Connecting) point of the internally-externally related meridians in use. Shu-Stream points are where the qi starts to pour down the meridian. They are known to alleviate heaviness and pain in the joints. On Yin Meridians, Shu-Stream points are identical to the actions of Yuan-Source points.

Needling: Perpendicular insertion .3 - .5 cun. Keep clear of the radial artery.
