Do Those Who Practice Alternative Medicine Keep Themselves Aware Of The Advances Of Modern Science?

Things that were old become new again especially in the world of medicine and healing. This article “Do Those Who Practice Alternative Medicine Keep Themselves Aware Of The Advances Of Modern Science?” offers some

The advances of science, particularly those in metabolism, genetics, and nanotechnology, promise unprecedented medical techniques that will revolutionize the practice of medicine in the coming years. Things like targeted drug delivery, RNA interference, patient specific therapy, gene therapy, stem cell therapy, cloning, etc, will do so much in the fight against disease. As an example, work on T-cell engineering, combined with advances in our understanding of cellular communication in the immune system, will soon allow physicians to expose immune cells to particular antigens and tell them to attack and kill any cell that has it, or not to. Imagine what such techniques could do for cancer, or organ transplantation. We could train immune cells to target specific cancer cell lines, and they will wipe them out with ease. We could transplant organs from any person into any person. This is a tiny fraction of the possibilities promised by the advances of immune based therapy, and there are so many more fields. I could go on for days about the future of modern medicine. The ability to deliver RNA molecules to specific cells is already becoming a reality. Imagine the ease with which diseases like Type I diabetes mellitus, or cystic fibrosis could be treated when we can simply stick RNA into the cell that will activate the necessary genes, or serve as a template for the missing proteins. Imagine how quickly disease like Huntington’s will be wiped out.

Will the alternative practitioners stay in the loop as modern science advances? If they elect the not to, how long do they really think they’ll have a customer base?

This is an interesting question. Both modern and alternative medicine are moving towards integrating there procedures and practices with one another.  This is resulting to both learning that each has plenty to offer and receive from the other.
Traditional medicine has been used by peoples all over the world for centuries. Herbs and natural methods have been used to treat illnesses for thousands of years. In many parts of the world traditional medicine is still the primary method of healthcare. Even in “developed” countries traditional or alternative methods are gaining traction. It is estimated that more than eighty percent of the population in 1st world countries have tried therapies such as acupuncture or even homeopathy. When surveyed US students in medical school over seventy four percent of those students felt that Western medicine and traditional or alternative therapies have a place with one another.

Modern medicine is lacking in the world of new treatment options. New drugs take years to develop and the cost is almost prohibitive. This coupled with increasing resistance to drugs are making modern pharmaceuticals ineffective. Herbs and natural treatments are being used to help treat many illnesses and diseases.

Modernising tradition

But making traditional medicine truly mainstream — incorporating its knowledge into modern healthcare and ensuring it meets modern safety and efficacy standards — is no easy task and is far from complete.

And there is rising concern among conservationists that a growing traditional medicine market threatens biodiversity through overharvesting of medicinal plants or increased use of body parts from endangered animals, such as tigers, rhinos and elephants.

Beyond the sustainability of natural resources, marrying traditional and modern medicine faces numerous challenges that stem from key differences in how each is practiced, evaluated and managed (see Table 2).

Traditional medicine

Modern medicine

Knowledge protection

Open access

Closed, patent-protected


Ad hoc during consultation with the patient

Pre-determined, and once tested in clinical trials cannot be changed unless re-tested


Virtually none, though some countries are trying to introduce rules and standardisation

Extremely tight, to the point that bringing drugs to market now costs billions of dollars


No formal testing as knowledge of the effectiveness is handed down through generations

Rigorous trials that happen in different phases, first testing for safety, then efficacy


Unfixed: the amount of medicine given might be roughly similar, but the active ingredient (which is what dosage really is) can vary hugely

Fixed doses that tend to vary only slightly with age or weight, or disease severity


Lengthy, and the patient is asked about a wider range of questions than just their symptoms

Consultations in both primary and secondary care tend to be brief and focused, especially as national health systems come under strain


Both systems of medicine require lengthy training over many years but with traditional medicine, knowledge is often passed one-to-one through families, and practitioners are often born into a family of healers

Often vocational: health professionals go through formal training in schools and universities

Table 2: Key differences between traditional and modern medicine

Protection and piracy

One of the most striking differences between traditional and modern medicines is the legal protection given to knowledge.Traditional practitioners have historically shared their knowledge and experience freely — defining ‘open-access’ before the term even existed. Modern medicine, on the other hand, has stringent intellectual property laws and a highly evolved patenting system used to protect knowledge about drugs or medical techniques.

As Western researchers realise the wealth of knowledge stored in traditional medicine systems, and the need for new drugs becomes more urgent, many scientists have begun searching indigenous sources for new drugs: a term dubbed ‘bioprospecting’ (see Bioprospecting).

In some cases, researchers have sought patent protection for medicinal compounds that had already been used for centuries to treat disease. An example is the 1995 patent on an anti-fungal neem derivative commonly used in Indian traditional remedies. The European Patent Office (EPO) granted a patent to the US Department of Agriculture (USDA) and the multinational WR Grace and Company.

The Indian government convinced the EPO to revoke the patent on the basis of prior use, but it took five years and millions of dollars.

This plundering of freely available indigenous resources has been termed ‘biopiracy’ and is a strong example of the challenges facing efforts to take traditional medicine mainstream.

Some regions have tried to tackle the problem by enacting laws to protect indigenous knowledge. For example, Cusco, in Peru, last year outlawed the exploitation of native species for commercial gain, including patenting genes or other resources the trees contain (see Peruvian region outlaws biopiracy).

India’s Council for Scientific and Industrial Research (CSIR) takes a more pragmatic approach to bridging the divide. In 2001, it launched a traditional knowledge digital library (TKDL). From last year, the EPO has been able to consult the 24 million page, multilingual database on traditional remedies and medicinal plants before granting patents (see BioMed Analysis: Keep traditional knowledge open but safe).

Many other countries have, or are considering establishing, similar databases to protect their local resources, including China, Ghana, Malaysia, Nigeria, South Africa, Tanzania, Thailand and some nations in the Middle East.

Regulating remedies

Beyond differences in indigenous and Western knowledge systems, efforts to make traditional medicines mainstream also have to cope with significant differences in regulation.

Every country has a national drug authority of sorts, responsible for administering and managing modern medicines and setting drug policies.

The problem with traditional medicine is that it often means different things to different people. A single medicinal plant may be classified as a food, a dietary supplement or a herbal medicine, depending on where you are.

A 2005 survey of WHO member states found that 84–90 countries (around 60 per cent) had no national policy, laws or regulations for traditional medicine (although more than half of these proposed developing them) [5]. These are often the countries where traditional remedies are used the most (see Figure 1).

Figure 1: Worldwide regulation of traditional medicine [5]

And those countries with TM legislation take diverse approaches to licensing, dispensing, manufacturing and trading traditional remedies.

The lack of regulation means there are just as many fake remedies and false practitioners as there are genuine treatments. And that can have fatal results. For example, last year, two people died and nine were hospitalised after taking fake anti-diabetic traditional medicine, used to lower blood sugar, in the Xinjiang Uygur Autonomous Region in China. [6]

For most of the past decade, the WHO has been working to develop international guidelines and technical standards to help countries formulate policy and regulations to control traditional medicines.

Testing times

If regulation of traditional and Western medicines varies, so too do methods for evaluating and testing them.

Modern drugs go through a rigorous series of laboratory tests and clinical trials before coming to market. Modern medicine has developed powerful methods for proving effectiveness, testing for safety and standardising good manufacturing practices.

In contrast, few scientific tests are done to evaluate traditional medicine products and practices. Quality tests and production standards tend to be less rigorous or controlled and in many cases, practitioners may not be certified or licensed.

Of course, some researchers believe that putting a drug that has been tried and tested in thousands of people for decades or centuries through the same hoops as a brand new chemical is not appropriate.

But many agree that before a traditional medicine can be imported into a conventional framework of pharmaceuticals, it will require reassessment.

In some cases, this means adapting standard methods to cope with ethical issues that do not arise with conventional drug development. US researchers Jon Tilburt and Ted Kaptchuk have, for example, suggested that clinical trials of traditional medicines must follow different rules for research ethics (see Box 2). [7]

Box 2: Rules of research ethics for clinical trials of traditional medicines*

1. Justifiable social need for the research

The rationale for testing a traditional medicine in a clinical trial cannot simply be that it already exists as a treatment. There must be both a social need and some preliminary evidence that the medicine will not negatively counteract other medicines used to treat the same disease. Different stakeholders will define social need in different ways — for example, a government may want to prevent any other party from commercialising the treatment and health campaigners may want the clinical trial to try to produce better drugs.

2. Appropriate definitions of inclusion and exclusion criteria, and outcome measures

Concepts of health and sickness differ between modern and traditional medicine. For example, Western researchers would probably categorise heart failure in patients according to the New York Heart Association classification. But practitioners of traditional Chinese medicine (TCM) would see heart failure as a heart yang chi deficiency or a kidney yang deficiency, categorising patients based on pulse or tongue examination. Researchers testing a herbal remedy for heart failure would need to take both biomedical and TCM criteria into account for the results to be valid from both perspectives.

3. Innovative protocol design

Drugs brought to market by putting traditional medicines through clinical trials must be rigorously tested but researchers will need to think carefully about how best to design their protocol. Standard methodologies may not be appropriate for a medicine that contains a mixture of active ingredients or in treatments that vary between practitioners. But adaptations of standard protocols could accommodate many of these issues. For example, cluster randomised controlled trials could be rigorous while allowing for practitioner variability.

4. Establishing standards for safety and evidence

The familiarity of traditional medicines, and their widespread use, could bias some researchers towards a good safety profile. Care is needed early on to determine safety requirements.

Inherently variable

Ethical issues aside, it can be extremely difficult to apply modern methods — developed to test standardised drugs — to the inherently diverse range of products that are traditional medicines.

Many traditional medicines are made by crushing the leaves or bark of plants and trees, and the resulting mixture can contain hundreds of potentially active molecules. Identifying these is hard enough — testing each one for safety and effectiveness is practically impossible.

And unlike many modern pharmaceuticals, the quality of source material for traditional medicines varies greatly, even within individual countries. This is true both because of differences in the genetic material used as well as other variable factors such as environmental conditions, harvesting, transport and storage.

Dosage is similarly varied. Modern medicine demands standard dosages that tend to vary only with bodyweight or severity of disease. Traditional healers are more likely to give their patients a unique dosage or combination of medicines that is concocted only during the consultation and based on the patient’s symptoms.

Poor evaluation results may therefore be the result of any number of factors — from the mistaken use of the wrong species of plant to contamination with toxic substances during storage to overdosage. They do not necessarily indicate that the medicine is an inappropriate candidate for modern drug development.

Culture clash

Similarly, if a traditional medicine is deemed clinically ineffective by modern standards, it doesn’t mean it cannot work as a therapy. Homeopathy, for example, seems to work despite hundreds of clinical trials suggesting that it has no biological effect. Many scientists believe this is a placebo effect generated because homeopathy practitioners spend far longer listening to what their patient has to say than do conventional doctors. [8]

But while the placebo effect can certainly be beneficial, many would consider it unethical to prescribe clinically ineffective treatment in order to induce this benefit.

Then there is the issue of combining traditional medicines and modern drugs. The belief system that accompanies traditional medicine can sometimes interfere with modern treatments. In 2009, Kumanan Wilson, of the University of Toronto, Ontario, Canada, and colleagues reviewed barriers to malaria treatment in Africa in the journal BMC International Health and Human Rights. [9]

In Africa alone, malaria is estimated to kill one million people, more than 90 per cent of whom are children under five. Wilson’s team found that a reliance on traditional medicines and linked cultural beliefs — such as the idea that a child with convulsions is possessed or haunted by spirits and would die if taken to hospital — was a major barrier to effective treatment for malaria.

In many of the studies the team reviewed, respondents said that traditional therapies such as herbal remedies were used as a first-line treatment before modern drugs.

New techniques for old treatments

New scientific techniques are also being applied to traditional medicine in the search for modern drugs. These innovative approaches are developing at breakneck speed (see Table 3).



Reverse pharmacology

Researchers start with the end product, a clinically useful compound for example, and work backwards to find out what it contains and how it functions. This can offer clues about how particular medicines work, and where they act in the body.

High-throughput screening

This advanced screening relies on high-speed data processing and sensitive detectors to conduct millions of biochemical, genetic or pharmacological tests in a few minutes. The process can quickly identify active compounds that affect particular biological pathways.

Systems biology

This holistic approach aims to understanding the way different chemicals and metabolic processes interact within the body. Since traditional medicines often have numerous active ingredients, it could be used to measure the whole body’s response to the mixture of compounds.

Table 3: How to create modern drugs from traditional compounds [10]

In India, the CSIR has teamed up with several public and private partners to conduct clinical trials on herbal products generated through reverse pharmacology. It says this has resulted in wider acceptance of Ayurvedic traditional medicines and promises cheaper, faster and more effective drugs. [10]

And in Africa, at the Kenya Medical Research Institute, scientists at the institute’s Centre for Traditional Medicine and Drug Research are testing thousands of plants in the hope of finding a new antimalarial (see Turning plants into pills in Kenya). The team has had a handful of promising leads, though none has yet been effective enough to pursue as a candidate drug.

Gaining ground

Integrating traditional medicine into modern healthcare is certainly being taken seriously by some of the biggest research bodies worldwide. In 2007, 62 countries had national institutes for traditional medicine — up from 12 in 1970. [11]

The US National Institutes of Health, for example, houses an organisation called the National Center for Complementary and Alternative Medicine (NCCAM), which this year has a budget of US$128.8 million.

NCCAM funds research into how acupuncture, herbal supplements, meditation, or osteopathy can help treat conditions such as cancer, cardiovascular disease, and neurological disorders.

Developing countries with ancient histories of traditional medicine are also hunting for ways to modernise their own medical heritage. In China, modern and traditional medicine are practiced alongside each other at every level of the healthcare system. The government gives equal weight to developing both and China has a large and active research community on ‘integrative medicine’.

In Latin America too, several countries are working to provide modern and traditional health care side-by-side (see Modernising traditional medicine must work for locals).

African governments, including those of Ghana and Nigeria, are rolling out educational campaigns and launching anti-counterfeiting technologies to better monitor drug procurement. And initiatives such as the African Network for Drugs and Diagnostics and Innovation are encouraging the mining of traditional medicine.

So traditional medicine has much to offer global health, especially as new drugs have never been more urgently needed. If both developed and developing countries joined research capacities in equitable collaborations, new scientific techniques could spark a revival in global health research and development.
