BASIC CONCEPT & PHYSIOLOGICAL ACTIONS OF BODY FLUIDS IN TCM
Body Fluids (Jin Ye) refers to all liquids in the body other than Blood. They are divided into two kinds: Jin and Ye. Jin are the clear, light and watery Fluids which flow easily and quickly. They circulate with Defensive Qi in the space between skin and muscles. They can manifest as sweat, tears, saliva and mucus. Ye are the thick, heavy, turbid and dense Fluids which flow slowly with the Nutritive Qi in the Interior. They moisten brain, spine, bone marrow, joints and sense Organs.
