Why are moon bears kept for bile?

Bear bile farming persists because demand and profit continue despite alternatives.

In brief

Moon bears are kept for bile because bear bile contains ursodeoxycholic acid, historically used in traditional medicine. Modern synthetic and plant alternatives exist, but demand and profit keep bile farming alive in some places. Bile farming keeps bears for extraction of bile used in some traditional products.

Why this question matters

Bear bile farming is one of the starkest examples of an animal kept alive for repeated extraction.


The welfare-first answer

The welfare-first answer is abolition plus care for survivors. Confiscated bears cannot simply be released after years in cages.


What to do next

Support sanctuaries that provide veterinary treatment, naturalistic enclosures and long-term behaviour recovery.

What WARN does
