Bile bears or battery bears are bears kept in captivity to harvest bile, a digestive juice produced by the liver and stored in the gall bladder. The Asiatic black bear (Ursus thibetanus) is the species most commonly farmed, however, the sun bear (Helarctos malayanus) and the brown bear (Ursus arctos) are also used. Both the Asiatic black bear and the sun bear are listed as Vulnerable on the World Conservation Union's (IUCN's) Red List of Threatened Animals. When extracted, the bears’ bile is a valuable commodity for sale as an ingredient in traditional Chinese medicine. Asiatic black bears are also known as moon bears because of the cream-colored crescent moon shape on their chest.

China was the first country to use bear bile and its gall bladder as an ingredient in Traditional Chinese Medicine (TCM). Bear bile was first recorded in "Tang Ban Cao" (Newly Revised Materia Medica, Tang Dynasty, 659 A.D.). For thousands of years, the traditional way to acquire bear bile was to kill a wild animal and remove its gall bladder. The use of bear bile in medicines was adopted by Korea and Japan centuries ago and today, the use of TCM is widespread not only in Asia but also throughout Asian communities in other areas of the world, including Europe and America.
In the early 1980s, bile bear farms began appearing in North Korea, eventually spreading to other regions.
The practice of bile bear farming is ethically controversial because of cruel treatment of the bears alleged by bile-farming opponents. The Chinese government, however, has attempted to justify bear farming, claiming that the farms promote captive breeding and reduce the need to hunt and kill wild bears. Nonetheless, the bears continue to be hunted in the wild in order to supply bears to the bile farms, allegedly because of difficulties with captive breeding where a gall bladder can fetch up to U.S.$3,000 - $5,000.
Breeding bears for use on bile farms has been shown not to reduce the impact on wild bear populations; records indicate that cubs are routinely taken from the wild to stock bear farms and rising prices of wild bear cubs on the black market indicate high demand. It has also been found that that farms in Lao PDR, Myanmar and Viet Nam show low success in breeding bears and these bear populations are in decline in bear-farming countries in Southeast Asia and China.
Housing and husbandry
To facilitate the bile milking process, the bears are commonly kept in extraction cages, also known as crush cages, that measure around 79 cm x 130 cm x 200 cm (2.6 feet x 4.4 feet x 6.5 feet) for an animal that weighs between 50 to 120 kilograms (110 to 260 lb). While this allows for easier access to the abdomen, it also prevents the bears from being able to stand upright, or in some cases even greater restriction. In two model Chinese bile farms, the Humane Society of the United States (HSUS) reports that the bears are moved to the crush cages for milking, but the rest of the time live in a cage large enough to stand and turn around.
Longevity and mortality
Farmed bile bears are often malnourished and in poor health, living to an average age of five years; healthy captive bears can live until age 35 and wild bears live to 25-30 years. If the bears live past age five, they are most often killed around age 10, since by then their productivity usually drops off. They are then sold for their meat, fur, paws and gall bladders. Bear paws are considered a delicacy, and have been seen priced at $250.
Farmed bile bears can suffer from a variety of physical ailments which include loss of hair, malnutrition, stunted growth, muscle mass loss, and often have their teeth and claws extracted.
Living for 10–12 years under such circumstances results in severe mental stress and muscle atrophy. The Chinese media reported an incident in which a mother bear, having escaped her cage, strangled her own cub and then killed herself by intentionally running into a wall. World Animal Protection sent researchers to 11 bile farms. They reported seeing bears moaning, banging their heads against their cages, and chewing their own paws (autophagia).
There are several extraction methods.
- Repeated injection in which an ultrasound imager is used to locate the gall bladder which is then punctured and the bile extracted.
- Permanent implantation of a tube through the abdomen and into the gall bladder. According to the HSUS, the bile is usually extracted twice a day through such implanted tubes, producing 10–20 ml of bile during each extraction
- Catheterization involves pushing a hollow steel or perspex catheter through the bear's abdomen. The use of metal catheters has been banned, although the HSUS writes that bile bears are still seen with catheters in them.
- The "full-jacket" method uses a permanent catheter tube to extract the bile which is then collected in a plastic bag set in a metal box worn by the bear.
- The "free drip" method is regarded as more humane. A permanent hole, or fistula, is made in the bear's abdomen and gall bladder, from which bile drips out freely. The wound is vulnerable to infection and bile can bleed back into the abdomen, causing high mortality rates. Sometimes the hole is kept open with a perspex catheter, which HSUS writes causes severe pain.
- Removal of the gall bladder whole is sometimes used.
There is no definitive estimate of the number of Asian black bears in the wild: Although their reliability is unclear, rangewide estimates of 5–6,000 bears have been presented by Russian biologists. Rough density estimates without corroborating methods or data have been made in India and Pakistan, resulting in estimates of 7–9,000 in India and 1,000 in Pakistan. Unsubstantiated estimates from China give varying estimates between 15–46,000, with a government estimate of 28,000. Some estimates put the total Asia-wide population as low as 25,000.
In July 2000, Animals Asia Foundation, a Hong Kong based charity, signed an agreement with the Chinese government to remove 500 endangered Asian black bears from bile farms in Sichuan province and work towards ending the practice. Today, the China Bear Rescue has placed 219 previously farmed moon bears at a Sanctuary in Chengdu, and is helping to advance the concept of animal welfare in China.
World Animal Protection conducted a study in 1999 and 2000, and estimated that there were 247 bear bile farms in China, holding 7,002 bears, though the Chinese government called the figures "pure speculation." The Chinese consider bear farms a way to reduce the demand on the wild bear population. Officially 7,600 captive bears are farmed in China. According to Chinese officials, 10,000 wild bears would need to be killed each year to produce as much bile. The government sees farming as a reasonable answer to the loss of wild bears from poaching, and at the same time are indifferent to the cruelty issues that concern Western animal rights activists. However, the government's agreement to allow the rescue of 500 bears may represent a softening of this stance.
In 2013, estimates of bears kept in cages in China for bile production range from 9,000 to 20,000 bears on nearly 100 domestic bear farms. China has repeatedly been found to be the main source of bear bile products on sale throughout South-East Asia; this international trade in their parts and derivatives is strictly prohibited by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).
There are estimated to be 4,000 bile bears in Vietnam, where their bile can sell for 100,000 dong (~US$6.25) per millilitre (with 37,500 dong a week regarded as the poverty line for an urban resident).
In 2009, according to the Korean Environment Ministry, there were 1,374 bears raised at 74 farms across South Korea. In Korea it is legal to raise bears for bile and bears older than 10 years old can be harvested for their paws and organs. By 2012, it is estimated the number of bears in Korean farms will have risen to about 1,600.
In Laos, bear bile can sell for 120,000 kip (~US$15) per millilitre (with 240,000 kip being the average monthly wage in the country). the number of bile bears is estimated at more than 100 individuals.
Treatments and products
The monetary value of the bile comes from the traditional prescription of bear bile by doctors practicing traditional Chinese medicine. Bear bile contains ursodeoxycholic acid (UDCA). It is purchased and consumed to treat hemorrhoids, sore throats, sores, bruising, muscle ailments, sprains, epilepsy, reduce fever, improve eye-sight, break down gall stones, act as an anti-inflammatory, reduce the effects of over-consumption of alcohol, and to 'clear' the liver. It is currently found in various forms for sale including whole gall bladders, raw bile, pills, powder, flakes and ointment.
Because only minute amounts of bile are used in traditional Chinese medicine, a total of 500 kg of bear bile is used by practitioners every year, but according to WSPA more than 7,000 kg is being produced. The surplus is being used in other non-essential products such as throat lozenges, shampoo, toothpaste, wine, tea, eyedrops, and general tonics.
In January 2006, the Chinese State Council Information Office held a press conference in Beijing, during which the government said that it was enforcing a "Technical Code of Practice for Raising Black Bears," which "requires hygienic, painless practice for gall extraction and make strict regulations on the techniques and conditions for nursing, exercise and propagation." However, a 2007 veterinary report published by the Animals Asia Foundation (AAF) stated that the Technical Code was not being enforced and that many bears were still spending their entire lives in small extraction cages without free access to food or water. AAF also noted that the free-dripping technique promoted in the Technical Code was unsanitary as the fistula created to access the gall bladder allowed for an open portal through which bacteria could infiltrate the abdomen. The AAF report also stated that surgeries to create free-dripping fistulae caused bears great suffering as they were performed without appropriate antibiotics or pain management and the bears were repeatedly exposed to this process as the fistulae often healed over. The free-dripping method still requires the bears to be prodded with a metal rod when the wound heals over and, under veterinary examination, some bears with free-dripping fistulae were actually found to have clear perspex catheters permanently implanted into their gall bladders. In addition to the suffering caused by infection and pain at the incision site, 28% of fistulated bears also experience abdominal hernias and more than a third eventually succumb to liver cancer, believed to be associated with the bile-extraction process.
There are more than 50 legal herbal alternatives and many synthetic alternatives.
The active therapeutic substance in bear bile—and in the bile of all mammals—is ursodeoxycholic acid (UDCA). Before the manufacture of UDCA by pharmaceutical companies, bear bile was prescribed by practitioners of traditional Chinese medicine because it contained a higher percentage of UDCA than the bile of other mammals. However, modern chemistry has made this fact irrelevant. Today, pharmaceutical-grade UDCA is now collected from slaughterhouses, then purified and packaged under trade names such as Ursosan, Ursofalk, Actigall, and UrsoForte. Chinese doctors have also endorsed several herbal substitutes, which provide a cheap, effective and readily available alternative.
Substances in mammalian bile other than UDCA, such as cholesterol, have never been demonstrated to have any healing effect in humans. Despite this observation and the availability of affordable pharmaceutical-grade UDCA, some practitioners of traditional Chinese medicine continue to prescribe whole bear bile for their patients and reject any sort of modern substitute.
Price of products
Raw bile can sell for as much as U.S.$24,000 a kilogram, approximately half the price of gold.
A report published in 2013 stated that a poacher in North America can usually get U.S.$100 to $150 for a gall bladder, but the organs can fetch U.S.$5,000 to $10,000 in the end-market once they are processed into a powder. The report also stated that the HSUS indicated a bear gall bladder can cost more than $3,000 in Asia. A TRAFFIC report estimated that prices for whole gall bladders were as low as $51.11 (Myanmar) and as high as $2,000 (Hong Kong SAR). For gall bladder by the gram, the least expensive was $0.11 per gram (Thailand) and the highest was $109.70 per gram (Japan).
Pill prices ranged from as low as $0.38 per pill (Malaysia) to $3.83 per pill (Thailand).
In China, there are two moon bear rescue centers, one in the Sichuan province and one in the Yunnan province. The rescue centers have already rescued approximately 300 bile bears. The bears are kept at the rescue centers where they are allowed to run around and play. The rescue centers not only rescue bile bears but also rescue some brown bears, dogs, cats, etc. The rescue center was opened by Jill Robinson from England.
It is claimed by animal welfare advocates that bear bile is not needed to make traditional Chinese medicine or other products as many herbs, such as coptis or rhubarb, can be used as alternatives for bear bile.
In 2010, the Guizhentang Pharmaceutical company was one of the most successful bile extraction companies in China, paying some 10 million yuan in taxes. In 2012, the company tried to go public in the Shenzhen stock exchange and proposed to triple the company’s stock of captive bears, from 400 to 1,200. This provoked a large response from those opposed to bear bile farming, and met heavy challenges from activists, internet users and protesters. This was followed by a number of controversies along with public interviews.
