Contraindications and Cautions


Great Lo of the SP: hundreds of vessels flowing into the sides and the chest from this point, all in contact with the longitudinal Lo vessels of all other meridians.

Opens the Chest to move Qi and Blood (angina, etc)
Firms the Sinew and Joints
This channel presides over Yin and Yang, and via the SP irrigates the five viscera. If the Tai Lo is excessive, there are pains all over the body: disperse this point. If the Tai Lo is empty, all the joints become flaccid: tonify this point. Binds the tendons and bones.
