The seats of kapha

Kapha resides in the stomach, chest, head, throat and all the joints and, aided by mobile vāta, carries out its work in the whole body. The commentary names the five kaphas by site (kledaka in the stomach, avalambaka in the chest, tarpaka in the head, bodhaka in the throat, śleṣmaka in the joints), and a footnote explains each: kledaka moistens food in the stomach and aids digestion, avalambaka strengthens the heart and supports the other kapha sites, tarpaka nourishes the senses above the neck, bodhaka in the tongue aids the perception of tastes, and śleṣmaka lubricates the joints like oil on a cart's axle.
