The Chinese media has reported on an extraordinary account of a mother bear saving her cub from a life of torture by strangling it and then killing itself.
The bears were kept in a farm located in a remote area in the North-West of China. The bears on the farm had their gall bladders milked daily for 'bear bile,' which is used as a remedy in Traditional Chinese Medicine (TCM).
It was reported that the bears are kept in tiny cages known as 'crush cages', as the bears have no room to manoeuvre and are literally crushed.
The bile is harvested by making a permanent hole or fistula in the bears' abdomen and gall bladder.
As the hole is never closed, the animals are suspect to various infections and diseases including tumours, cancers and death from peritonitis.
The bears are fitted with an iron vest, as they often try to kill themselves by hitting their stomach as they are unable to bear the pain.
A person who was on the farm in place of a friend witnessed the procedures and told Reminbao.com that they were inhumane.
The witness also claimed that a mother bear broke out its cage when it heard its cub howl in fear before a worker punctured its stomach to milk the bile.
The workers ran away in fear when they saw the mother bear rushing to its cub's side.
Unable to free the cub from its restraints, the mother hugged the cub and eventually strangled it.
It then dropped the cub and ran head-first into a wall, killing itself.
Many TCM practitioners have denounced the use of bear bile in their treatment as there are cheaper herbs and synthetics that can be used in its place.
Bear bile is traditionally used to remove 'heat' from the body as well as treat high fever, liver ailments and sore eyes.
