About PC-8 Palace of Toil
PC-8 Laogong occupies a unique position as a Fire point on a Fire meridian (the ying-spring point of the Pericardium/Jueyin channel), giving it an intense, concentrated heat-clearing action focused specifically on the Heart system. The name 'Palace of Toil' refers to the palm as the palace of labor -- the center of the hand's ceaseless activity -- and also to the fire that accumulates in the Heart from the toil of emotional and mental overexertion.
The palm of the hand is one of the body's major energy emission points. Qigong practitioners train to project qi through Laogong, and the warmth felt in the palms during meditation or energy work is attributed to the activation of this point. In therapeutic context, Laogong drains the excess heat that builds up in the Heart from emotional stress, overwork, and stimulant overuse, manifesting as mouth sores, restless agitation, insomnia, and the hot, sweaty palms of anxiety.
Laogong corresponds to KI-1 Yongquan on the sole of the foot, and together these two points form the hand-foot axis of the Heart-Kidney relationship. Where KI-1 draws energy downward into the earth, PC-8 can either release heat outward through the palm or draw healing energy inward. The palm-rubbing technique -- vigorously rubbing the palms together and then placing them over the eyes, face, or abdomen -- is a foundational qigong self-healing practice that activates Laogong's dual capacity for clearing and nourishing.
