Can chicken gizzard lining (Ji Nei Jin) be used to treat indigestion?
Generally speaking, chicken gizzard lining (Ji Nei Jin) can be used to treat dyspepsia. The detailed explanation is as follows:

Chicken gizzard lining contains components such as gastric hormones, keratin, various vitamins, and digestive enzymes. These components can stimulate the gastric glands to secrete gastric juice, increase gastric acidity and digestive capacity, thus promoting gastrointestinal motility and accelerating food digestion and absorption. For dyspepsia caused by overeating or food retention, which manifests as symptoms like abdominal distension, loss of appetite, and nausea, chicken gizzard lining can effectively alleviate these discomforts and exert therapeutic effects by enhancing digestive function. Whether it is dyspepsia in adults caused by overeating or food accumulation in children due to weaker spleen and stomach function, chicken gizzard lining can exert certain regulatory effects.
When using chicken gizzard lining to treat dyspepsia, attention should be paid to adjusting the dosage according to age and condition; especially for children, its use should be guided by a physician. At the same time, dietary regularity should be maintained during administration, and excessive consumption of greasy and cold foods should be avoided to better support the efficacy of chicken gizzard lining. If symptoms of dyspepsia do not improve or worsen after taking it, prompt medical attention should be sought.
