Can ass hide glue be eaten after ten years

Ass hide glue is usually not recommended to continue to eat after ten years of storage. The shelf life of ass hide glue is generally 3-5 years. If the shelf life is exceeded, mildew, moth damage or loss of effective ingredients may occur, mainly due to improper storage environment, packaging damage, raw material quality difference, microbial pollution, drug effect reduction and other factors.

The main ingredients of ass hide glue are collagen and trace elements, which are easily affected by temperature and humidity after long-term storage. If stored in a cool and dry environment with intact packaging, there may only be slight discoloration or texture hardening after ten years, but the active ingredients have been significantly reduced. Traditional Chinese medicine believes that aged ass hide glue is mild, but modern pharmacological studies have confirmed that its active ingredients will degrade over time, and its hemostasis and blood tonifying effects will significantly decline.

If the surface of ass hide glue is found to have mildew, moth eaten marks or smell, it indicates that it has deteriorated. Mouldy ass hide glue may produce harmful substances such as aflatoxin, which may lead to gastrointestinal discomfort and even liver damage after consumption. Some businesses may reprocess and sell expired ass hide glue, which poses a higher security risk.

It is recommended to choose regular channel products and pay attention to the production date when purchasing ass hide glue. After opening, it should be sealed and refrigerated and used within the warranty period. For ass hide glue stored for ten years, no matter whether its appearance is normal or not, it is not recommended from the perspective of safety and effectiveness. If the aged ass hide glue needs to be used under special circumstances, it should be treated after being identified and confirmed by a professional pharmacist to be free of deterioration. It can be used externally or in combination with other medicinal materials according to medical advice. For daily health care, it is recommended to choose ass hide glue produced within 3 years, and use it with red dates, medlar and other ingredients to enhance the absorption effect.
