Killing of Endangered Animals Continues for Usage in Traditional Medicine and Bogus Remedies

2013; American Botanical Council
Since HerbalGram’s 2010 exposé on the usage of endangered animals in
cultural healing systems and the botanicals that can replace tiger bone wines
and bear bile soups,1 some nonprofit organizations and a few
countries’ governments have made progress toward realizing the end of this
heinous situation. But the outlook for most involved species, unfortunately,
remains bleak and uncertain, as apparent in the World Wildlife Fund’s (WWF)
December 2012 announcement that the illegal trade of wildlife has become the
“fourth largest illegal global trade, after narcotics, counterfeiting, and
human trafficking.”2
Tigers
Tigers most
often are killed for their bones, which are used in various remedies, and other
tiger parts also are used medicinally, including the blood, penis, tail, and
eyes.1 Although tiger-based tonics, wine, and other products
are used much less commonly now than they were throughout their long history in
Traditional Chinese Medicine (TCM), the trade in illegal tiger parts continues
and the challenges faced by these revered cat species remain serious.
“It’s difficult
to say with certainty whether the situation [for tigers] has improved or got
worse, but one thing we can say with certainty is that the trade is certainly
ongoing,” said Richard Thomas, communications coordinator of TRAFFIC
International (email, March 27, 2013).
Since the
2010 HerbalGram piece was
published, the International Union for the Conservation of Nature (IUCN) has
continued to classify tigers as endangered, as they have been since 1986.3 WWF
recently announced that tiger populations are further decreasing, and poaching
for tiger body parts — most often destined for China — is their primary threat.3,4 In
March 2013, TRAFFIC issued an updated report on the illegal tiger trade, noting
that at least 1,425 tiger carcasses and body parts were seized by officials
during the last decade.5
“There are an
estimated 3,200 tigers left in the wild today and in most places where tigers
live, the population remains in jeopardy,” said Barney Long, WWF’s Asian
species expert (email, January 24, 2013). “Destinations for tiger parts differ
based on the product. For example, there is demand coming from Chinese Tibet
for skins and pelts; demand from China and Vietnam for tiger bone, etc. In
recent years, the largest factor contributing to the illegal trade of tiger
parts is their status symbol value in China and Vietnam, which is driving their
use in tonic wines and as exotic meats.”
Although more
than a dozen botanical alternatives to tiger remedies have been identified and
encouraged in the past — including Chinese clematis (Clematis chinensis, Ranunculaceae) root and rhizome, pubescent
angelica (Angelica pubescens,
Apiaceae) root, dong quai (A. sinensis)
root, and Sichuan lovage (‘Chuanxiong’;
Ligusticum sinense, Apiaceae)
rhizome, among others1 —
most current efforts focus on enhancing law enforcement in countries of
concern, as well as repopulating wild tiger populations.
Unfortunately,
in February 2013, the nonprofit Environmental Investigation Agency released a
report claiming that the Chinese government is quietly fueling domestic trade
in tiger parts, and — despite the country’s 1993 ban on tiger medicinal products
— the federal government has issued “secret” notices to traders that encouraged
the production of wine made from the bones of tigers from Chinese tiger farms,
which reportedly house 5,000 to 6,000 tigers as of early 2013.6
Bears
Bear bile
contains high levels of the anti-inflammatory compound ursodeoxycholic
acid (UDCA), and it has been used medicinally in TCM for many years.1 Due
to increased awareness of the cruel way in which bile is harvested from the
gallbladders of live bears — that are often kept in inhumane conditions on
overcrowded, filthy bear farms — its usage in TCM has decreased somewhat.
However, bear bile is increasingly being sold for non-scientific and
non-traditional uses in unregulated shops and markets, in addition to being given
as an expensive gift to represent wealth or status.
“Bear bile,
historically, has been used in limited amounts for specific diseases and
illnesses, and nothing could be further from the truth of how it’s exploited
and sold today,” said Jill Robinson, founder and CEO of Animals Asia, an animal
welfare organization (oral communication, January 27, 2013). “In Vietnam, for
example, we’ve been picking up bile that originated in China and is being sold
as hangover cures. It’s also being sold in wines and tonics and, despite the
fact that every farmed and extracted bear has contaminated bile, it continues
to be ingested by people who are persuaded by the farmers that it can cure a
multitude of ills.”
Still, the
situation for bears, according to Robinson, is improving. In January 2013,
Animals Asia won its fight against a pending eviction from the Vietnam Bear
Rescue Centre in Tam Dao National Park, which is home to many bears that the
organization saves from farms and the chain of illegal trade.
“Vietnam,” said
Robinson, “has seen some quite interesting developments in that the official
government figure there has reduced the number of bears, from an estimated
4,000 on the farms to about 2,400. So the numbers are coming down on the farms
and that gives us a lot of confidence in the work that we’re doing.”
But, Robinson
also recognized that the number of farmed bears in China is
increasing. “China is at the heart of this industry; there is no question
about it,” she said. The Chinese public, however, is learning more about
the cruelties of the bear bile trade and also is speaking out against it more
frequently. According to Robinson, “bear farming” was one of the top 10
most-discussed topics in China in 2012, and at one point was the second
most-searched term on the Chinese Internet. And more and more celebrities are
endorsing the anti-bear-farming cause, she said, in addition to a new
documentary film that went viral in China.
“What we’ve
seen in China in the last year is unprecedented outrage across the country,” said
Robinson. “I’ve never seen anything like this in 20 years of campaigning
against bear farming. And it gives us a lot of confidence that we’re turning a
corner.”
In May 2013, The New York Times reported that
vehement protests in China recently resulted in the withdraw of a Shenzhen
Stock Exchange application by Guizhentang Pharmaceutical, the country's largest
bear bile extract manufacturer.7
Animals Asia
recently launched its “Healing Without Harm” campaign, which has successfully
convinced about 140 TCM pharmacies to stop selling, stocking, and prescribing
bear bile. In the next year, the organization will continue to focus on these
efforts, and is expecting more pharmacies, including some large chain
businesses, to join in taking the pledge. Futhermore, Professor Yibin Feng of
the University of Hong Kong — who conducted research in 2009 on botanicals to
replace bear bile — will soon disseminate informational documents on the
medicinal efficacy of plants in the goldthread genus (Coptis spp., Ranunculaceae), an antibacterial, antiviral,
anti-inflammatory, and anti-hypertensive herb that is a promising
alternative to bear bile.
Rhinos
For thousands
of years, the keratin-rich horn of the rhino has been a common TCM treatment
for numerous conditions, including fever, convulsions, and hemorrhaging.1 Although
alternatives to rhino horn have been encouraged, poaching of rhinos has only
escalated. The South African government announced that poachers killed a record
668 rhinos in 2012, 50 percent more than the 448 rhinos killed in 2011, and
significantly more than the 13 rhinos killed in 2007.8 More
than 500 rhinos already had been killed in the first seven months of 2013.9
Rhino poaching also has increased in other African countries, such as Kenya, as
well as in some parts of India — where officials estimate one average-sized
horn yields $90,000 to $100,000.10
“We can say
with absolute certainty that the last three years have been getting
progressively worse [for the rhino],” said Thomas of TRAFFIC.
“We’re dismayed,
obviously; we’re very upset,” added Susie Ellis, executive director of the
International Rhino Foundation (IRF). “Again, the root cause is essentially the
same and the primary reason behind it seems to be that there is an emerging
market in Vietnam, where rhino horn is purported to be a cancer cure. But it is
also emerging as a high-value gift that people give one another. It’s not used
decoratively; it’s just used for medicinal purposes. It’s also being used as a
hangover cure in Vietnam. These are new uses” (oral communication, January 23,
2013).
Ellis noted
that the demand for rhino horn also is present in China, where she said the use
of it is ongoing and not showing signs of decreasing. Ellis purported that
the current Asian demand partly stems from the increasing Asian presence in
Africa, where Chinese companies are being awarded construction and
infrastructure contracts.
Perhaps a
greater cause for the demand, Ellis continued, is the strong cultural belief in
these remedies in Vietnam, China, and other Asian countries, where rhino horn
is available for sale whole over-the-counter and ground-up in prepared
remedies. Thomas of TRAFFIC added, “It’s important to stress that the horns are
not in demand for traditional medicine — they are being sought for new uses; in
Viet Nam ground horn is used as a body detoxifier — essentially a hangover
cure, also given as a high value gift, and to some extent also used as a
supposed (though medically unsupported) cancer cure. The traditional,
centuries-old use of rhino horn is in a concoction used to treat high fever.”
IRF and other
groups are planning to implement an education campaign in Vietnam informing the
public that these remedies are baseless and have no scientific
support. Additional conservation and wildlife groups have been trying to
quell poaching through the dispersion of a similar message. The theme of 2011’s
World Rhino Day, for example, was “Rhino Horn is Not Medicine,” and at the
Convention on International Trade in Endangered Species of Wild Flora and Fauna
(CITES) meeting in early March 2013, Thomas said, “countries were instructed to
develop strategies to reduce the demand for rhino horn. This would naturally
include the promotion of alternatives to the use of horn as well as more
frequently employed measures such as stronger penalties for those caught
trafficking, etc.”
Ellis also noted the importance of
educating the public that real animals are being killed.
“There’s not much wildlife left in
Vietnam, for example, and I’m not sure that the end-user always knows that [the
remedy] even comes from a live animal that was killed,” she said. “The majority
of rhinos are killed with AK-47s. Some of the more sophisticated poachers are
coming in and — obviously have the involvement of veterinarians — with helicopters
and are darting the animals with drugs. But, by and large, they’re so
interested in getting every single shred of horn that they hack down into the
animal’s skull. They bleed to death; they die from trauma and shock.
Occasionally they live, but only one or two actually survived more than a few
days.”
Because it is very difficult to
address the deep, cultural root of the problem, however, Ellis’s organization
and others largely focus on deterring and preventing poaching, as well encouraging local authorities to punish those involved
with poaching.
Future Outlook
Offering hope
for the future of these beloved animal species is the increasing presence and
awareness that illegal wildlife trafficking is obtaining among charity groups,
the media, and public and government officials. Several wildlife groups
are taking action to address the overall situation, such as TRAFFIC’s
distribution of educational wildlife crime kits to customs officials in
Southeast Asian countries.11 Robinson of Animals Asia emphasized the
important role that the public has to play, especially by contacting relevant
authorities, as well as the media in the United States and in China.
“Please, please
to anyone reading [this] article that is remotely interested and wants to
help,” she said, “don’t underestimate the power of your pen and how much you
can help. Please, please, keep raising it.”
Recent journal
articles suggest interest in using DNA testing to detect the presence of
endangered animal species in Chinese medicines. A February 2013 article
published in PLoS One, for example,
discussed the use of DNA barcoding to successfully identify endangered Saiga
antelope and Sika deer particles in known animal-based products.12
According to the Chinese authors, “… We believe that the identification (DNA
barcoding) of threatened animals combined with seeking substitutions
(bio-response) can yet be regarded as a valid strategy for establishing a
balance between the protection of threatened animals and the development of
traditional medicine.”
A similar
paper, published in PLoS Genetics in
2012, details DNA testing that revealed Asiatic black bear and other threatened
animals in TCM samples, substances that “were rarely declared on the product
packaging.”13 High-throughput sequencing of DNA, the Australian
authors wrote, could be a cost-effective and efficient way to screen TCM
products, especially when genetic reference databases become better
established.
Still, the
situation remains complex and is far from being solved, especially considering
the large role played by unregulated shops and markets that sell remedies for
uses with no scientific or traditional support. And the problem touches many
animals in addition to the species covered in this article; pangolins (a small,
scale-covered Asian mammal), the most commonly traded mammal — two species of
which are endangered — are killed for their scales and blood;14
manta rays are killed for their gills that are bogusly purported to treat
cancer, chickenpox, and suppressed immune systems.15 The list goes
on and on.
Thomas said he
thinks the key to seeing a significant improvement is to address possibly the
most difficult aspect of the situation: reduce demand for the endangered
wildlife products in the first place.
“Close that
down,” he said, “and you take away the reason to source and supply it. There
needs to be a coordinated strategy, ranging from simple public awareness
raising of the impacts the demand is causing; more information about what the
actual rather than perceived medicinal benefits of the product; what legal,
cheaper, effective alternatives may exist, etc. Such activities should be
focused in user groups/destination countries. Alongside there should be other
measures, such as higher penalties, stronger monitoring, and enforcement to
reduce or curtail the supply of the product. These should be applied across the
entire trade chain — from source to end user.”
