Side effects of chicken gizzard lining (Fructus Galli Gigerii)

Chicken gizzard lining (Fructus Galli Gigerii), as a traditional Chinese medicinal herb, is primarily used to treat indigestion, food stagnation, and related symptoms. Its side effects are mainly associated with method of use and dosage. The following are potential side effects of chicken gizzard lining:

1. Reduced digestive function: Chicken gizzard lining helps promote gastrointestinal motility and improves digestion. However, long-term use may lead to dependency of the gastrointestinal system on this substance, thereby weakening the body's natural digestive capacity, reducing gastrointestinal motility, and potentially causing bloating.

2. Risk of gastric ulcers: Although chicken gizzard lining promotes gastrointestinal motility, taking it when physically weak or on an empty stomach may irritate the gastric mucosa, increasing the risk of gastric ulcers. This may result in symptoms such as stomach pain, nausea, and vomiting. In severe cases, gastrointestinal bleeding may occur, manifesting as hematemesis (vomiting blood) or melena (black, tarry stools).

3. Worsening of bruising and swelling: Chicken gizzard lining contains a pro-coagulant factor. Excessive intake by patients with external injuries or skin bruising may cause prolonged retention of blood stasis, potentially exacerbating bruising and swelling. This can lead to increased swelling and intensified pain at the site of injury or bruising.

When using chicken gizzard lining, it is essential to strictly follow medical guidance and adhere to the prescribed dosage and administration instructions.
