Introduction to Dried Pig Bile Powder
Dried Pig Bile Powder is the dried product of bile obtained from the pig (Sus scrofa domestica Brisson). It is prepared by filtration, drying, and pulverization of fresh pig bile.
As a traditional Chinese medicinal material, pig bile powder has been used for centuries for its heat-clearing, moistening, detoxifying, and cough-relieving properties. In modern pharmaceutical applications, it serves as a valuable source of bile acids, primarily hyodeoxycholic acid (HDCA). Per the Chinese Pharmacopoeia, the content of hyodeoxycholic acid (C₂₄H₄₀O₄) in dried pig bile powder shall not be less than 16.0% on a dried-basis.
Recent scientific research has revealed additional therapeutic potential. A 2025 study published in the World Journal of Diabetes demonstrated that pig bile powder improves glucose homeostasis by promoting GLP-1 (glucagon-like peptide-1) secretion through the inhibition of farnesoid X receptor (FXR) signaling, highlighting its potential as a therapeutic strategy for metabolic disorders.
Dried Pig Bile Powder supplied by Huilin is manufactured under strict quality control standards, complies with Chinese Pharmacopoeia (ChP) requirements, and is supported by full documentation including COA and batch traceability. We offer private label, OEM, and ODM services with competitive pricing and reliable supply chain support for bulk wholesale customers worldwide.

Process Flow
Dried Pig Bile Powder is produced following the method prescribed in the Chinese Pharmacopoeia:
- Sourcing – Fresh pig bile is collected from healthy pigs from qualified sources
- Filtration – Bile is filtered to remove impurities and particulate matter
- Drying – Filtered bile is dried using appropriate methods (spray drying or low-temperature drying)
- Pulverization – Dried bile is ground into a fine powder
- Quality Control – Each batch is tested for appearance, identification, hyodeoxycholic acid content (≥16.0%), water content (≤10.0%), reducing sugars, foreign organic matter, and bovine/sheep bile contamination
- Packaging – Powder is packaged under controlled conditions in moisture-proof, light-protected containers

Frequently Asked Questions (FAQ)
Q: What packaging options do you offer?
A: We offer 1 kg foil bags for samples, 5–10 kg bags for intermediate quantities, and 25 kg fiber drums for bulk shipments. Customized packaging and private labeling are available upon request.
Q: Can Dried Pig Bile Powder be exported globally?
A: Yes, we export to most regions worldwide with full export documentation and regulatory support.
Q: What is the difference between dried pig bile powder and purified bile acids?
A: Dried pig bile powder is the crude dried product containing a mixture of bile acids, bile pigments, mucoproteins, and other components. Purified bile acids (such as hyodeoxycholic acid, cholic acid) are individual compounds extracted and purified from bile powder for higher-purity applications.
Q: Is Dried Pig Bile Powder suitable for cell culture applications?
A: It is commonly used in microbiological culture media as a selective agent. For cell culture applications, additional processing to remove endotoxins and other impurities may be required.
Q: Is Dried Pig Bile Powder a pure compound or a mixture?
A: It is a natural mixture containing bile acids (mainly hyodeoxycholic acid, cholic acid, and chenodeoxycholic acid), bile pigments, mucoproteins, and other components. It is not a purified single compound.
Q: How is the quality of Dried Pig Bile Powder controlled?
A: Each batch is tested per Chinese Pharmacopoeia standards for appearance, TLC identification, hyodeoxycholic acid content (≥16.0%), water content (≤10.0%), reducing sugars, foreign organic matter, and bovine/sheep bile contamination.
Q: Does Dried Pig Bile Powder contain any additives or preservatives?
A: No, our product is produced through a simple, clean processing method (filtration, drying, pulverization) without any synthetic additives or preservatives.
