SPOTLIGHT ON THE TRADE IN WILD PLANTS
Wildcrafted for Green (Gullible?) Customers
By Chrissie Wildwood
With the soaring trade in herbal medicine,
essential oils and natural skincare products, ‘wildcrafted’ and
‘sustainable’ are the current buzzwords used by traders of medicinal and
aromatic plants. Words that summon images of smiling workers gathering leaves,
bark, and flowers from forest, meadow and mountainside - not indiscriminately,
but with knowledge and sensitivity to ensure survival of plants and habitats for
future generations. In fairness, some companies do try to ensure that wild
plants are harvested ethically and sustainably. However, there is no legal
definition of the terms, and buying herbal medicines and essential oils with
these labels is no guarantee they are from sustainable sources.
While the herbal medicine market has taken its
toll, undoubtedly the most voracious plunderers of Earth’s finite resources
are the multinational drug companies. Renewed interest by the pharmaceutical
industry in plant medicines (to isolate and/or standardise their ‘active
principles’ or manipulate plant genes to gain lucrative patents), combined
with the lack of effective international agreements on conservation of habitats,
has resulted in ‘slaughter harvesting’ of medicinal plants and massive
depletion of habitats. Even smaller companies producing over-the-counter herbal
remedies are collectively contributing to ecological devastation.
The true scale of the international trade in
medicinal plants is difficult to assess because of lack of reliable statistics
and trade secrecy. According to research carried out by the World Wildlife Fund
(WWF), a staggering 90 per cent of all medicinal and aromatic plants traded
throughout the world are still collected from the wild. More conservative
estimates from herb traders interviewed by myself give a figure of around 60-80
per cent. In view of this, it’s hardly surprising that an alarming number of
medicinal plants have become threatened in recent years.
Following is a mere selection of endangered or
otherwise ‘at risk’ species, gleaned from more extensive lists compiled by
conservation agencies such as the WWF and United Plant Savers in the USA. Those
plants marked with an asterisk are valued not only as herbal medicines, but also
for their essential oils.

The following plants are cited by the United
Nations’ Convention on International Trade in Endangered Species (CITES),
which means international trade in wild harvested or artificially propagated
material is subject to licence.
*Agarwood (Aquiliara malaccensis and other Aquilaria
species), also known as aloeswood, eaglewood and gaharu. Found in eastern
India, though now on the verge of extinction there. Populations are widespread
but patchy in Indonesia, Malaysia, the Philippines, Papua New Guinea, Laos,
Burma, Vietnam, and Cambodia.
Aloe species (except Aloe vera), from
*Amyris (Amyris balsamifera), from the South
Pacific and West Indies. .
Guaiac (Guaiacum officinalis and G. sanctum), from
the West Indies.
Indian Yew (Taxus wallichiana), also found
in Afghanistan, China, Nepal, Pakistan.
Himalayan Mayapple (Podophyllum hexandrum).
Kutki (Picrorhiza kurroa), from the
Orchid species (Orchidaceae), all species
are protected throughout the world.
Prunus bark (Prunus africanas), from the wet
montane forests of Africa.
*Rosewood (Aniba roseodora,) and all related
species found in Brazil and other parts of South America.
*Sandalwood (Santalum album), from India,
Indonesia and other parts of southeast Asia. In fact, wherever the tree grows it
is at risk from over-harvesting.
Snakeroot (Rauvolfia serpentina), from
India, Malaysia and Indonesia.
*Spikenard (Nardostachys grandiflora), from
The manner of collection of the recently endangered
Prunus bark (Prunus africanas) in Cameroon and Zaire is a sad reflection
of practices adopted by the international trade in medicinal plants as a whole.
Extracts of the bark are used in pharmaceutical preparations in several European
countries to treat early stages of benign prostate disease. Businessmen, or
their agents, contact local villagers for collection of the bark, which is
stripped indiscriminately causing many trees to die. It’s difficult for poor
people to resist the chance of an income, no matter how appallingly small, even
if they are aware that the long-term effects may be devastating.
IS CULTIVATION THE ANSWER?
Even though there has been an enormous increase in
herb cultivation in recent years, wild harvesting in still prominent in many
parts of Europe (including France, Spain and Eastern Europe), also the USA,
China, India, Africa, Indonesia, and other regions of the globe. Many medicinal
and aromatic plants are unsuited to high volume monoculture, or the market is
too small to make commercial harvesting financially viable.
Therefore, the problem of over-exploitation of wild
plants cannot be solved by cultivation alone. In any event, most experts believe
there is not enough cultivatable land available to meet escalating world demand,
unless yet more rainforest is destroyed. The only way forward is to find ways of
supporting existing sustainable practices of wild harvesting, alongside
sustainable methods of cultivation (i.e. without the use of artificial
fertilisers and agrochemicals). No easy task, for we must also make provision
for the social and economic needs of the world’s poorest people. Progress will
be largely dependent on support from governments and industry.
Another point, while sustainable cultivation is to
be encouraged, indiscriminate and opportunistic planting is an increasing threat
to fragile ecosystems. In Madagascar, for example, virgin forest has been
cleared in recent years to make way for the cultivation of Pelargonium species
for distillation of geranium oil. While in Indonesia, the boom in patchouli oil
prices (from the species Pogostemon cablin), prompted large-scale
deforestation on the island of Nias to make way for plantations. In July 2001,
catastrophic floods and landslides swept away hundreds of homes and killed 50
people on the Island, the direct result of deforestation in the upper Masio
River watershed. Adding to the tragedy, patchouli oil prices have since
plummeted, so the plantations have been abandoned.
ENTER THE SOIL ASSOCIATION
The Soil Association (the largest independent
inspection body for organic agriculture in the UK) has recently drawn up
comprehensive standards for sustainable wild harvesting. SA certification is
regarded as more than just a mechanism for controlling indiscriminate gathering
of wild plants. As well as ensuring maintenance of biodiversity (the broadly
diverse forms into which all living things have evolved), it is also seen as
being of fundamental importance for the preservation of cultural traditions,
providing income for some of the world’s poorest people.
All fine and dandy on paper, but from my own
researches I cannot help but conclude that the SA has grown too big for its
roots. True, the organisation may well be doing an excellent job in monitoring
organic standards for agriculture in Britain, but wildcrafting throughout the
world is something else entirely. Due to reluctance of traders to reveal sources
of wild harvested plants, it is impossible for any single agency to know the
origin of every plant traded - and thus, extremely difficult to estimate
sustainable yields. What we do know is that plants are commonly gathered from
remote regions of the globe, usually by local people who sell the plant material
on to agents. Therefore, whether the Soil Association’s monumental task can be
effectively implemented and monitored remains to be seen.
Added to the SA’s inexperience of wildcrafting is
their lack of knowledge of the complexities of the essential oil trade. Indeed,
as we shall see, the certification of organic essential oils is another example
of premature branching out. Incidentally, other EU approved organic inspection
bodies such as Ecocert in France, Belgium and Germany can be criticised for
making the same errors of judgement.
As a supporter of the organic movement for nearly
30 years, it came as a shock to discover that the SA had awarded certified
organic status to a source of geranium oil from recently cleared rainforest in
Madagascar. On further enquiry, in transpired that they were also about to
certify a ‘sustainable’ source of oil from endangered Indian sandalwood (Santalum
album). Likewise, a source of Rosewood oil (Aniba spp). After
bombarding the SA with informative and heartfelt pleas for sanity, thankfully
they have agreed to reconsider certifying these oils. However, it’s too soon
to celebrate, as the outcome will depend on the vote of the SA’s leading
membership (mostly traders with vested interests). So watch this space!
In personal correspondence with the SA’s
President Jonathan Dimbleby (broadcaster, journalist and organic farmer),
although he sympathises with my general concerns, he admits that the SA
certification is ‘bound to be an evolving process, very often in uncharted
territory.’ I intend to write back, pointing out that surely anyone paying a
premium for a certified organic ‘wildcrafted’ herb or essential oil has
every right to demand competence and expert knowledge from the certifying body?
SPOTLIGHT ON THE AROMATICS TRADE
Readers of my books will know that I’ve always
advised against the use of rosewood oil because of the environmentally
destructive method of its production. As for sandalwood, until recently, like
many other aromatherapists I had allowed myself to succumb to the rosy picture
painted by traders - that for every tree felled, three more were planted. This
same mantra is now being intoned for rosewood. Alas, the true picture is imbued
with murky tones. Let’s take a closer look at these two popular aromatics and
consider the reasons why they have no place in holistic healing.
The essential oil of Santalum album is found
mainly in the heartwood and roots of mature trees. Thus, the tree must be felled
in order to capture its precious bane. The sweet, soft-balsamic aroma is
immensely popular in perfumery and as an ingredient in upmarket body care
products. In aromatherapy, sandalwood is used mainly for its calming effect on
the nerves and for skin treatments.
Few sandalwood trees are left in the Indonesian
archipelago due to over-exploitation, while relatively recently discovered
supplies in Papua New Guinea and the South Pacific are in danger of being
squandered by local villagers, who fell them before maturity. Of the traditional
areas in Southeast Asia where sandalwood is found, only India has made a
significant effort to create sandalwood plantations, all of which are government
owned. However, this parasitic tree is notoriously difficult to cultivate
because the seed will usually only germinate once it has passed through a bird.
The self-seeded saplings are protected from browsing animals to form semi-wild
Despite the Indian government’s restrictions on
the trade in sandalwood (which allows a limited amount of the essential oil to
be traded on the world market), clandestine cutting and smuggling remains a
serious threat to the species, causing law and order problems in areas bordering
the state of Tamil Nadu. Smugglers have bribed hundreds of villagers to take
part in illicit cutting and carrying, paying them twice as much as they can earn
performing forest chores for the government. Alas, the gangs will often stop at
nothing to secure their bounty - even murders have been committed in the name of
sandalwood! The poached wood is taken north to the distilleries and incense
factories of Uttar Pradesh and Bihar. Much of the illegally distilled oil finds
its way to Indonesia from where it is sold to traders throughout the world.
Another major threat to sandalwood in southern
India is seasonal forest fire, usually started by graziers and others employing
unsustainable methods of land usage through ignorance of the need to maintain
biodiversity. The fierce heat renders the trees susceptible to spike disease. A
sandalwood tree infected with this mycoplasma organism usually dies within three
Due to its value and scarcity, sandalwood oil is
especially vulnerable to adulteration. It is also fairly easy to replicate the
aroma of sandalwood in the laboratory, the true nature of the product usually
only detectable to the expert nose. Analysis of various essential oils obtained
from different aromatherapy suppliers conducted by the British consumer magazine
Health Which? (February, 2001) revealed that, in one case, a synthetic
sandalwood perfumery chemical was being peddled as authentic sandalwood oil to
unwitting aromatherapists. The source of the ‘oil’ was traced to a
specialist wholesale supplier to the profession and a member of the prestigious
Aromatherapy Trade Council. True, the use of synthetic sandalwood odourants is
one way to save trees. Omitting to declare the true nature of the product on the
label, however, is an act of fraud.
There is no doubt that it would be advantageous to
reduce the world demand for sandalwood. The only way to do ensure such an
outcome is for us to stop buying it!
The Asian trade in sandalwood and other endangered
species will continue unabated, but this is no reason for other countries to be
complacent. Some have argued that there is nothing wrong in using sandalwood oil
if it can be obtained from a legal, traceable and sustainable source. Indeed,
moves are afoot to establish such guarantees.
However, the real issue is that certification will
give the product an ethical image and increase its desirability to the
eco-minded - the very people who would choose not to buy the product if
presented with the whole picture! Awarding organic status to a consignment of
oil will do nothing to curb the illicit trade in sandalwood, which is playing a
major role the tree’s demise.
Wherever the tree is found growing, there will
always be someone lurking in the shadows awaiting the opportunity to hack it
ABOUT AUSTRALIAN SANDALWOOD?
As an alternative
to precarious Asian sources, there is growing interest in Australian sandalwood (Santalum
spicatum). The Department of
Conservation and Land Management (CALM) in western Australia is overseeing the
supply and sustainability of sandalwood stands for extraction.
A huge amount of money has been poured into the project, and so the
producers of the extract (as we
shall see, ‘pure essential oil’ is a misnomer) are doing their utmost to
sell it to aromatherapists (among others).
plantations are being established, the newly planted trees will take at least
30-50 years before the oil content (found mainly in the heartwood) becomes
In the meantime, trees will continue to be felled mainly from wild stands
in the arid interior.
In such harsh conditions, it can take 100 years for a tree to grow
sufficiently large enough to meet harvesting criteria.
Quite a different picture from that painted by the producers who are
claiming that trees as young as 15 years can produce a viable amount of
are also estimating that even without a replanting programme, there are enough
trees to continue exploiting for 100 years.
What is forgotten is that the demand for the product is likely to
escalate as Asian sources continue to diminish and pressure mounts to expand or
maintain the harvest
- even if it is not sustainable.
Indeed, as Ian Kealley from CALM points out, ‘It will take a strong
government and industry to resist the financial incentives not
Therefore, such estimates amount to little in a rapidly expanding market.
Furthermore, at this time no one can be certain that the new plantations
will flourish or expand sufficiently to replace the harvest from natural stands.
process used to obtain the extract involves a combination of solvent extraction
and steam distillation (authentic essential oils are extracted solely by steam
distillation or by cold expression in the case of citrus fruit).
Another process extracts the aromatic entirely by solvents.
The favoured solvent is hexane (a highly toxic petrochemical) because it
has been found to extract the maximum constituents from the wood. The resulting aromatic liquid is quite different in chemical
structure from an essential oil as it includes non-volatile elements that are
never found in steam distilled oils.
Nevertheless, recent studies indicate that the properties of Santalum
are anti-microbial, fungicidal and anti-inflammatory.
few people realise that the producers of the extract were also directly involved
in the commissioning of acute dermal and oral toxicity tests on animals carried
out by the Danish laboratory Scantox in the year 2000 (currently unpublished
And yet, the aromatic is an ingredient in certain ‘cruelty free’
cosmetics sold in the USA and Australia!
Needless to say, I have reported this unsavoury truth to the Australian
animal rights organisation Choose Cruelty Free and they have promised to
to extraction of the aromatic, although virtually all traces of the
solvent are removed from the finished product, of more serious concern is the
potential adverse environmental impact.
No matter how careful the extraction process (the solvent is continuously
recycled) some will escape into the environment.
For this reason, truly holistic aromatherapists shun all solvent
extracted aromatics, including the ubiquitous jasmine absolute.
Certainly the use of hexane in the extraction process will preclude
Australian sandalwood from gaining certified organic status.
Rosewood trees (Aniba spp) are severely
threatened with few mature trees left standing. The species A. roseaodora from
the Brazilian Amazon Basin is on the verge of extinction resulting from
over-exploitation by the perfume industry. The essential oil is found in greater
abundance in the roots and heartwood of mature trees, which necessitates
felling. It is estimated that 3000 rosewood trees (of several species) are still
felled annually for the extraction of essential oil.
Contrary to one popular myth, rosewood plantations
have not been around since the 1930s! All evidence shows that the tree has
always been cut down from the wild, hence its severe decline. Research carried
out by the Global Trees Campaign confirms that there have been attempts in
recent years to establish rosewood plantations, but they have not been greatly
successful. However, the current AVIVE replanting project in the Silves area of
Brazil is looking more promising because the tree seedlings are being nurtured
in their favoured wild forest habitat. Fortunately for these plants it is not
their destiny to be ripped from the Earth for commercial gain. Essential oil can
be extracted by distillation of clippings of leaves and branches (even of fairly
young trees) to provide a non-destructive and truly sustainable source of oil.
Indeed, from the distillation project supervised by
WWF-Brazil, AVIVE will soon be providing an assured source of sustainable
rosewood leaf/branch oil. To ensure that local workers are not exploited, the
price received for the essential oil will be higher than the usual market price
in accordance with guidelines set by the international Fair Trade scheme. Due to
the scarcity of rosewood trees in the region, however, the amount of oil
produced will be limited and available from only a handful of essential oil
Unfortunately, at this time the aromatherapy
profession is less enthused about rosewood leaf oil because its aroma and
therapeutic properties are regarded as inferior (Incidentally, Tony Burfield is
aware of research suggesting that the leaf oil is probably equally efficacious.)
In aromatherapy, rosewood oil is used mainly in external applications (e.g.
massage) to alleviate nervous tension and anxiety through its sweet, woody-rose
fragrance. Therefore, it’s absurd to believe that rosewood leaf/branch oil,
whose aroma is only marginally different (i.e. with an additional citrus-like
top note) from that obtained from heartwood, could be noticeably less effective
for addressing emotional disharmony. Any essential oil whose aroma is pleasing
to the recipient has the potential to enhance mood and reduce stress when
A word of caution: once word spreads about a
sustainable source of rosewood leaf/branch oil, chances are the aromatherapy
market will become flooded with ‘ethically harvested’ rosewood oil. (Indeed,
similar has occurred with sandalwood, with some suppliers seriously claiming to
sell oil produced only from trees blown down in storms!) Therefore it’s
advisable to boycott rosewood oil, as many enlightened therapists and traders
have been doing so for over a decade - that is, unless indisputable documented
evidence of its provenance and sustainability can be acquired from the supplier.
Thus making it easier to take legal action against a trader making fraudulent
THE WAY FORWARD
Always remember that together we can make sweeping
changes for good. It’s incumbent upon us all to be ever vigilant about the
products we use in our daily lives. Don’t be afraid to ask awkward questions
of suppliers. Encourage them to investigate the provenance of every herb,
essential oil and related product that they sell. Never underestimate the power
of the Green coin. For choosing what to buy and what not to buy, collectively we
can improve the ethics of business and industry!
