It is a cholic acid extracted from pig bile, which can inhibit the formation of bile acid and dissolve fat, reduce blood cholesterol and triglycerides. It is suitable for atherosclerosis, Pertussis, diphtheria, staphylococcus, etc. have a certain antibacterial effect, can also be used as anti-inflammatory drugs, treatment of chronic bronchitis, pediatric viral upper respiratory tract inflammation and so on.

1.Hyodeoxycholic acid, also known as 3α,6α-Dihydroxy-5β-cholan-24-oic acid or HDCA, is a secondary bile acid, one of the metabolic byproducts of intestinal bacteria. It differs from deoxycholic acid in that the 6α-hydroxyl is in the 12 position in the former. The 6α-hydroxyl group makes HDCA a hydrophilic acid, a property it shares with hyocholic acid.

2.HDCA is present in mammalian species in different proportions. It is the main acid constituent of hog bile, and for this reason it was used industrially as precursor for steroid synthesis before total synthesis became practical.

3. It can lower blood cholesterol, treat and prevent coronary heart disease, hypertension, etc.
