•Channel and collateral 經絡:
Hand jue yin
ying-spring, fire point (滎火穴)
勞 láo : toil, labor, taxation, weariness
宮 gong : palace
PC-8 is located in the center of the palm. The point may be named Palace of Toil in reference to its location in the middle of the palm. The character 勞 láo suggest the task that the pericardium performs in protecting the heart. Palace 宮 gong may be taken as a reminder of the close relationship of the pericardium and the heart, the emperor (the heart) residing within the palace (the pericardium).
