Ox Bile Powder is a refined, dried powder preparation extracted from bovine bile, primarily containing conjugated bile acids (≥45% content, including taurocholic acid and glycocholic acid), bilirubin, lecithin, and other active components. Characterized by its distinctive bitter taste and aroma, this product is widely used in both traditional medicine and modern therapeutics. Its core functions include: promoting fat emulsification and absorption (via pancreatic lipase activation), regulating cholesterol metabolism (through HMG-CoA reductase inhibition), and enhancing intestinal barrier function. Recognized as an important digestive system drug ingredient by both the United States Pharmacopeia (USP) and European Pharmacopoeia (EP), it is particularly indicated for bile deficiency, biliary dysfunction, and fat malabsorption, with a recommended daily dosage of 250-500mg (calculated as total bile acids).
