INDIGENOUS peoples possess a vast body of knowledge that is of great value to humanity. Their creativity is reflected in the rich knowledge systems they have developed to conserve and carefully utilise Earth's resources.

And that creativity has healed, fed and clothed the world.

There is so much that mainstream society can learn from indigenous communities not only about plants, herbs and flowers that have the power to heal but also about this whole ethos of living harmoniously with nature.

Before you dismiss this as the romantic notions of environmentalists, pause a while to consider the contributions of indigenous knowledge to world health.

Three quarters of plants that provide active ingredients for prescription drugs came to the attention of researchers because of their use in traditional medicine.

Among the 120 active compounds currently isolated from the higher plants and widely used in modern medicine today, 75 per cent show a positive correlation between their modern therapeutic use and the traditional use of the plants from which they are derived.

More than two thirds of the world's plant species - at least 35,000 of which are estimated to have medicinal value - come from the developing countries.

At least 7,000 medical compounds in the Western pharmacopoeia are derived from plants.

According to Rural Advancement Foundation International estimates, US$32 billion (RM121.6 billion) of sales of pharmaceuticals worldwide are based on traditional medicines.

Yet the developing countries' exports account for only US$551 million - an incredible shortfall.

The importance of medicinal plants is highlighted by the work of the United States National Cancer Institute. Between 1986 and 1992, it paid for the collection of 23,000 plant samples of 7,000 species, almost all of which came from the South countries.

These staggering statistics were presented by Gurdial Singh Nijar, professor of law at Universiti Malaya, at the recent two-day seminar on "Biodiversity and the Knowledge Systems of Indigenous Peoples" jointly organised by The Indigenous Peoples' Network of Malaysia (Jaringan Orang Asal SeMalaysia) and UM's Law Faculty.

Indigenous knowledge and practices pertaining to medicinal plants are of particular relevance to Malaysia because of its desire to be a global player in the natural products sector.

The Malaysian Industry-Government Group For High Technology (Might) is now fine-tuning the National Herbal Products Blueprint for presentation to the Cabinet soon.

Proponents see opportunities in the rising demand for speciality natural products especially in the primary health care and cosmetics arena.

They point to two of Malaysia's many strengths: the plants growing in its forests and the local know-how about the myriad uses of medicinal plants.

Indeed, the creation of a depository of knowledge on the traditional uses of tropical herbs among Malaysians has been suggested as a way of expanding product development.

Many allude to the unique confluence of Asian health traditions found in Malaysia and say this cumulative knowledge could be used to advantage.

They suggest that a continuous effort be taken to document that knowledge to build up a rich database of medicinal plant applications.

It is sad if the proposed initiative overlooks the rich healing systems of the various indigenous peoples in Malaysia.

This is because Malaysia's indigenous communities are said to have mastered their practices and knowledge about the way plants and other biological resources are used to treat many ailments and for promoting health.

But how many realise that the source of the "local know-how" (as touted by the promoters of Malaysia's natural products sector) has actually come from the indigenous peoples themselves, a process which started when local communities began interacting with the indigenous folk?

"People must understand that the source of a lot of this knowledge is actually the indigenous peoples ... the cumulative knowledge which we have acquired for millennia, in fact. And this is not just true of Malaysia, it is also true of all Third World countries; so it is very critical for all of us to acknowledge this fact," says Gurdial, who is also consultant to Third World Network.

Even so, this is not a licence for mainstream society particularly researchers and bioprospectors to appropriate indigenous knowledge for commercial gain.

"There is a danger of that happening as well," says Gurdial. "It should not become another commodity. You must draw a balance between the commodification of indigenous knowledge and the undermining of that knowledge itself."

"Outsiders accuse us of being lokek (stingy) with our knowledge," says Jannie Lasimbang, a Kadazan from Sabah and secretary-general of the Asia Indigenous Peoples Pact which is headquartered in Chiangmai, Thailand.

"It is not that. We want it to be shared for the common good and not for the profit of a few multinationals which are controlling the pharmaceutical industry," adds Lasimbang, who was in Kuala Lumpur recently to take part in the UM discussions.

"Unless we are convinced that commercialisation will benefit us in every way and not just in monetary terms, we will continue to protect our knowledge."

The fear is real. The search for new drugs has taken pharmaceutical companies to species-rich countries. They engage ethnobotanists to work with indigneous peoples to scour and collect samples of plants for surveys.

These ethnobotanists talk to healers among the indigenous communities about secrets of a particular species.

"The use of this information about traditional medicinal uses of plants when screening them for biological activity has increased the rate of discovery of a lead chemical by some 400 to 800 per cent," writes Ong Chui Koon, senior manager at Sirim's Intellectual Property Services Section in his paper "Indigenous Rights and Forest Products".

"We cannot tell how many researchers or bioprospectors approach our villages because they come as tourists or they come without revealing their true intentions," says Lasimbang.

In response to that threat, Sabah has passed a law which controls access to indigenous knowledge and biological resources. Any researcher or bioprospector must obtain consent from the community concerned.

"That will, to some extent, protect us but not all the issues related to knowledge and biological resources are addressed," says Lasimbang.

For example, in areas claimed by both the indigenous communities and the State Government, the question of ownership of biological resources makes obtaining consent problematic.

That has prompted the indigenous communities in Sabah to draft a community protocol on the collection of biological resources and documentation of indigenous knowledge by outsiders.

"We are pushing for the State Government to accept the community protocol as a mechanism to obtaining consent," says Lasimbang.

Since the access law also talks about benefit-sharing of any commercial development accruing from usage of indigenous knowledge and biological resources, the community protocol will decide whether or not the researcher or bioprospector can carry out work in a particular area.

Sabah's indigenous communities find commercialisation of medicinal plants distasteful because these are tied to their spiritual beliefs.

Tijah Yok Chopil, a Semai from Kampung Chang Lama, Bidor, Perak, wants to know why herbalists from Peninsular Malaysia's Orang Asli community - a term which means "original peoples" - were not invited to form a group under the Health Ministry's programme to organise Malaysian practitioners of traditional and complementary medicine (New Sunday Times, March 4).

"Why were we not invited?" asks Tijah, one of the organisers of the UM discussion and deputy president of The Indigenous Peoples' Network of Malaysia.

"You can't say that you don't know about the existence of Orang Asli herbalists or holders of knowledge in traditional medicine. That is impossible because history tells you about our existence and our dependence on the forest and its products not only for food but for our medicinal needs as well," she says.

"I do not think for a moment that it is because the Government wants to exclude the Orang Asli," says Gurdial. "But for some reason, the indigenous peoples have been marginalised and we should rectify this."

He suggests that the Standing Committee for Traditional/Complementary Medicine, Malaysia, include representatives of indigenous peoples from Sabah and Sarawak as well as Orang Asli from Peninsular Malaysia.

Tijah says inclusion of Orang Asli in the Health Ministry drive to integrate relevant components of traditional and complementary medicine into the national healthcare system will result in the following: Orang Asli will be able to continue practising their healing systems and they will be part of the national development process besides receiving acknowledgement of their existence.

Deputy director-general of Health (research and technical support) Datuk Dr Mohd Ismail Merican says indigenous communities "can write to me officially, provided they have a registered body within which they are operating".

"Whoever contacts us must represent the majority. We do not want a situation where so many will come forward, once they know there is an avenue, and claim to be representing the Orang Asli. Once we receive the letter, we will certainly look into it and see whether they can come under one of the existing five umbrella bodies or otherwise," says Dr Ismail.

The spectre of cultural extinction hangs over indigenous communities who live close to, or within, forested areas in Malaysia.

Deforestation threatens to cut them off from their traditional cultures and this loss is the world's loss. Indigenous communities worry that one day when no forest is left, their descendants cannot keep cultural traditions such as natural healing.

For Nelson Janggai, an Iban from Miri, Sarawak, that day has already arrived.

He lives in an area which has no more forest resources.

"Traditional medicinal practices and knowledge are disappearing because the forest is gone and many of us who have converted to other religions are not allowed to practise our traditional systems, including that pertaining to health," says Janggai, also a participant at the UM seminar.

"The situation is compounded by the strong influence of urban lifestyles and modern medicine," he adds.

If dominant society continues to marginalise forested communities, a repository of knowledge based on an enormous amount of practical know-how will vanish.

But if we want to learn from them, it has to be on their own terms and in a mutually beneficial arrangement.
