Can Cockscomb Be Taken Long-Term?
Generally speaking, chicken gizzard lining (Ji Nei Jin) should not be taken for a prolonged period. Detailed explanations are as follows:

Although chicken gizzard lining can treat indigestion and related issues, it is not suitable for long-term consumption. As a traditional Chinese medicine used for eliminating food accumulation and improving digestion, its medicinal properties tend to be aggressive, primarily functioning by stimulating gastrointestinal motility and promoting secretion of digestive fluids. Prolonged use may continuously irritate the gastrointestinal mucosa, potentially disrupting the self-regulating function of the gastrointestinal tract and causing digestive dysfunction, thereby affecting normal digestion and absorption. For individuals with pre-existing spleen and stomach weakness, long-term use may further deplete the vital energy of the spleen and stomach, worsening their condition and leading to symptoms such as loss of appetite, abdominal distension, and diarrhea. Moreover, once the digestive issues have improved and food accumulation is no longer present, continued use of chicken gizzard lining is unnecessary, as long-term consumption will only impose additional burden on the body.
When taking chicken gizzard lining, the duration should strictly follow medical advice and the actual need of the condition. Once symptoms improve, medication should be stopped promptly; self-administration for a prolonged period is strongly discouraged. During the course of treatment, close attention should be paid to any bodily reactions, and if gastrointestinal discomfort or other abnormalities occur, use should be discontinued immediately and professional medical advice sought. Additionally, high-quality chicken gizzard lining should be obtained through legitimate channels to ensure its efficacy and safety, thereby achieving optimal therapeutic outcomes.
