Overview:
Ji Nei Jin, known as Chicken Gizzard Membrane in English, is the dried inner lining of a chicken’s gizzard. It has been used in Traditional Chinese Medicine for centuries to support digestion, resolve food stagnation, and promote the dissolution of urinary or biliary stones. With a neutral nature and sweet taste, it is commonly included in formulas for digestive disorders.
