After this film is peeled off, after being washed, dried and ground, it becomes a fine powder of light yellow or yellowish-brown color. According to traditional Chinese medicine theory, chicken gizzard lining powder has a very strong effect of invigorating the spleen and stimulating the appetite, aiding digestion and eliminating food accumulation. It is especially suitable for alleviating the problem of indigestion and abdominal distension caused by foods such as rice, flour, sweet potatoes and taro. This is because it is based on the analogy of the chicken's sandsac, which can grind grains, and its inner wall naturally has the ability to aid digestion. Therefore, it is often used in the treatment of indigestion in children or in adults with weak spleen and stomach and poor digestion.
