Commentary:

Gongshun is the Luo-Connecting point of the Spleen channel, connecting the Spleen with its related organ the Stomach. Together the Spleen and Stomach comprise the middle jiao and together provide nourishment for the whole body; the Stomach in its function of 'rotting and ripening' food and drink, and the Spleen in its function of transforming food and drink into Qi and transporting Qi to the rest of the body.

The principal action of Gongshun is, not surprisingly, then, the harmonizing of the middle jiao. As well, it is used to fortify the spleen, regulate Qi in the channel, and transform dampness.
