Curiosity

Wangu, 'Wrist Bones', is often underrated but very effective in treating joint disorders (especially of the wrist) and pain radiating along the Taiyang pathway. It also acts on the chest, useful in cases of fullness or emotional blockage. Often combined with SI3, LI5, and PC7 in joint treatment protocols.
