KI4 (Dazhong, “Dazhong means 'Great Bell'”) is the Luo-Connecting point of the Kidney Meridian point of the Kidney Channel Meridian. It is located on the medial aspect of the ankle, in the depression on the anterior border of the Achilles tendon, 0.5 cun inferior and slightly posterior to Taixi (KI3). It is located on the calcaneus, posterior to the talus. It tonifies the Kidney and strengthens the lower back, regulates the intestines, calms the spirit (Shen), clears deficiency heat, benefits the throat and moistens dryness, resolves damp-heat in the lower jiao.

As the Luo-Connecting point of the Kidney channel, Dazhong is pivotal for treating conditions involving both the Kidney and its paired Bladder channel, particularly urinary issues like retention or dribbling. It addresses both deficiency (lower back pain, fear, desire to be alone) and excess (constipation, urinary blockage) patterns. Its pathway to the throat and tongue makes it a key distal point for chronic sore throat, dry mouth, and difficulty swallowing due to Kidney yin deficiency.
KI4 is one of 27 points on the Kidney Channel Meridian. Nearby points:
