Exploiting medicinal plants
By Prof.Kirthi Tennakone

Plants are the most versatile chemists on earth. They manufacture food for humans and all animals and synthesise millions of other chemical compounds. Plants do this magnanimous work without engendering the habitat. Instead, provide oxygen for us to breathe and cleanse and beautify the environment.
Plants make starch and sugar out of water and carbon dioxide, harvesting energy from solar radiation via an intricate process not fully understood. If we were to make these food stuffs artificially using present – day chemical technology, the energy and machinery needed would disrupt the environment making it inhospitable and beyond repair!
Plants, as sessile organisms, defend themselves against intruders- herbivores, insects, fungi, bacteria and viruses- using an armoury of chemical agents. These chemical substances, plants synthesise; deter, control or eliminate harmful encroachers. Additionally, plants also accumulate chemical compounds as by – products of their biochemistry. So many of these compounds served humanity as medicines, flavours, perfumes, colouring agents or other useful chemicals.
The teacher of the legendary physician Jeewaka, a contemporary of Gautama Buddha, was Athreya of Taxila University. After seven years of study, to qualify Jeewaka as a physician, Athreya instructed him to fetch a plant from the forest that doesn’t have medicinal properties. Returning empty handed, Jeewaka exclaimed, such plants do not exist!
All ancient cultures have resorted to preparations made from plant derivatives for healing illnesses. The empirical knowledge gained by trial-and-error constituted the arts of traditional medicine. Frequently pseudoscience and spiritualistic ideas designed prescriptions. However, efficacious treatments continued for generations, carrying a wealth of information.
Rarely, plant species of the appropriate curative properties have been discovered by rational argument. The great Chinese physician Sun Siamio (581- 682 AD) noted that goiter occurs frequently in people who live in mountainous regions far away from the ocean. He argued that a deficiency of some ingredients present in the ocean could be the cause of goiter and prescribed seaweed. Amazingly, Simio’s prescription worked. In 1852, French chemist Adolphe Chatin attributed goiter to iodine deficiency. The chemical element iodine was first discovered by a chemist who experimented with seaweed ash.
After advent of modern scientific medicine, traditional recipes received fresh attention, leading to the discovery of drugs. Around 20 percent potent drugs used today originated from investigations based on this approach. According to United States Food and Drug Administration, about 60 percent anticancer medications are derived from plants.
In 1563, a Portuguese doctor, Garcia da Orta, who worked in Sri Lanka, wrote a book describing medical practices in the East, where he mentions the use of the herb Ekaveriya (Rauwolfia serpentina) by native physicians to treat snake bites. And quoted an exaggeration of a native poison healer, who said a mongoose preparing to attack a cobra consumed this herb. For more than 3000 years, Indian Ayurvedic physicians prescribed preparations of Rauwolfia to treat epilepsy, insomnia, diarrhoea and a host of other complications.
In Bihar, mothers induced sleep in their unruly children by feeding a soup blended with the roots of the Rauwolfia. Around the mid-1930s, Indian scientists knowledgeable in modern chemistry extracted the active ingredient in the herb and proved its sedative and anti- hypertensive properties. Unfortunately, the Indian chemists lost the opportunity to gain world recognition for discovery of the drug reserpine, a medicinally active compound in Rauwolfia.
The American chemist Robert Woodward, synthesised reserpine confirming its structure. He shared the 1965 Chemistry Nobel Prize for this work and other accomplishments. Arvid Carlsson, Swedish pharmacologist used reserpine to understand the neurochemical functions of the brain and shared Nobel Prize for Medicine and Physiology year 2000. Carlsson’s insightful studies carried out with reserpine from Rauwolfia catalysed the development of antipsychotic medications which revolutionised the treatment of mentally ill patients, closing lunatic asylums, where patients were sometimes chained and beaten.
The first chemically identified compound that successfully cured an infectious disease was quinine. The natives of South America used decoctions made from the bark of a tree later named Cinchona to treat fever. European scientists, having heard of the story, discovered quinine. The drug cured the malarial fever of billions over a period exceeding two centuries. The parasite developed resistance to quinine. In the early 1970s, Tu Youyou and her team in China, examined ancient literature and found a traditional prescription which said, a preparation made from the plant Artemisia annua cure fever. Following the prescription, they developed the new drug artemisinin to combat quinine resistant malaria. Tu Youyou shared the 2015 Nobel Prize for Physiology and Medicine. Now the parasite is developing resistance to artemisinin, and the world may need clues from ancient medicine to develop alternative remedies.
Sri Lanka has inherited a vast knowledge of written and unwritten prescriptions based on our rich diversity of plants. Our ancient physicians received worldwide recognition. According to the Ramayana, a genius physician named Sushena, who lived in Sri Lanka, knew the medicinal properties of thousands of plants and where they grew. A Chinese chronicle says that a merchant who visited Sri Lanka told the Emperor Xuanzong that in this land, an esteemed woman physician of vast pharmaceutical knowledge, cures the sick and prolongs their lives. Anuradhapura era physician Buddhist monk, Sakya Mitra was invited to China and served as the alchemist to the Royal Court of a Tang Dynasty Emperor.
Despite the exceptional background of traditional medicine and the availability of a diverse variety of plants at our doorsteps. And despite the longest and largest number of research projects in the area of Natural Products Chemistry, Sri Lanka has not succeeded in innovating a one single pharmaceutical to gain world recognition.
Our policymakers complain the country is not delivering innovations. They should critically examine why we have failed. It would be prudent for them to learn the stories of men and women who discovered proven drugs. They were curious and consistent workers who struggled hard to understand a problem and solve it. Our policies should nurture students and researchers of that caliber.
An article in the journal Nature, published just after the award of the Nobel Prize to Tu Youyou, refers to two comments made by acclaimed Indian scientists.
“Indian herbal research is like blind men and elephant story. Scientists doing bits and pieces of research for publication.”
“India is well behind both material facilities as well as intellectual and concerted efforts “
Needless to elaborate on the applicability of these comments to Sri Lanka. However, food for thought to evaluate and reform our institutions.
We also need to note the statement made by a member of the Nobel Committee in reference to the award of the prize to Tu Youyou:
“It is important that we are not giving a Nobel Prize for Traditional Medicine, and the award is only for scientific work inspired by traditional medicine.”
Traditional medicine is a virtue because of the information it has accumulated and the empathetic qualities of its practitioners, especially their older generation.
My grandfather was a native physician. We were told how he was awakened after midnight by people from neighbouring villages. He did not hesitate to get up, wrote prescriptions without charging a cent. If the condition of the patient, as described by the men who visited him, was noted to be critical, he consented to see the patient and walked miles barefoot along snake infested footpaths, accompanied by men carrying fire torches.
Our health care system and study of medicine would advance further, if traditional practice is motivated to be scientific and scientific practice is diverted to be more empathetic. Collaboration between two sectors would enable us to exploit the rich diversity of our flora to discover pharmaceuticals.

Addressing human rights needs multi-pronged approach
by Jehan Perera
The ongoing 63rd session of the United Nations Human Rights Council, which runs from September 7 to October 7, 2026, in Geneva is important to Sri Lanka. Its outcome will send a signal to other international actors, including the European Union, as to whether Sri Lanka’s reform policy is on track. The written update on Sri Lanka, prepared by the Office of the United Nations High Commissioner for Human Rights under High Commissioner Volker Türk and presented by Deputy High Commissioner Nada Al-Nashif, has taken a more holistic approach to the government’s performance over the past year. It acknowledged the progress Sri Lanka has made under the NPP government in relation to accountability for financial fraud and other economic crimes. At the same time, the High Commissioner’s update made clear that progress in relation to economic crime cannot be equated with progress in relation to accountability for grave human rights violations committed during the armed conflict and in other periods of political violence.
The government may have felt sufficiently confident that its response to the High Commissioner’s update could be handled by its representative in Geneva and did not require the attendance of Foreign Minister Vijitha Herath. Sri Lanka’s representative Sumith Dassanayake called for a fundamental review of country-specific mandates within the UN Human Rights Council. Sri Lanka has been facing repeated scrutiny in the form of successive UNHRC resolutions from 2012 onwards. Ambassador Dassanayake argued that such mandates should not continue indefinitely and must be regularly assessed against measurable objectives and tangible outcomes. This may reflect confidence that its record of reform is beginning to receive recognition internationally. The reports and statements at the Human Rights Council acknowledged progress in the government’s efforts to address corruption and economic crime.
The government’s anti-corruption drive has included investigations into allegations involving individuals who held the highest political offices in the country. The arrest of former President Ranil Wickremesinghe in connection with alleged misuse of public funds, and the investigation into the controversial SriLankan Airlines Airbus transaction involving former President Mahinda Rajapaksa’s son, are examples of the reach of these investigations. The arrest of SLPP National Organiser and Member of Parliament Namal Rajapaksa in connection with allegations relating to the Airbus purchase scandal has also demonstrated that the government is willing to pursue cases involving politically powerful figures.
Wide Range
The ongoing investigations appear to encompass a wide range of parliamentarians and government members, both past and present. They suggest that accountability for corruption is not being confined to lower-level officials or to individuals who lack political influence. This is precisely the kind of accountability that the public has long demanded and that previous governments have too often failed to deliver. The government is also reaching into the upper levels of the military hierarchies of the past. The case in which 11 young men, most of them Tamil, disappeared after being abducted in Colombo between 2008 and 2009 involved allegations that some families were asked to pay ransoms. The investigation into this case has reached senior military figures. The willingness to pursue such cases is important because it challenges the assumption that those who exercised power during the war are beyond the reach of the law. Such cases would provide a practical test of whether the government’s commitment to accountability for economic crimes is part of a broader commitment to the rule of law.
Success in prosecuting corruption cannot substitute for justice for those who were unlawfully killed, disappeared, tortured or otherwise victimised. The UN report noted that there had been no recognition or accountability for crimes under international law, gross human rights violations and serious violations of international humanitarian law committed by all parties during the war. The government has yet to establish a credible and effective process to address the many cases of enforced disappearance, extrajudicial killing, torture and other serious violations. The government needs to take the international commitments it has inherited on human rights issues seriously. It needs to adopt a multi-pronged approach and go beyond focusing primarily on financial and corruption-related accountability.
Need Action
As a member of the international community, Sri Lanka has a responsibility to abide by the commitments it has made. It cannot selectively uphold international obligations postponing those that are politically difficult. Also, as a small country, Sri Lanka has a self-interest in ensuring the survival of international law, which is all that it has to protect it from the depredations of the bigger international actors. The erosion of international law by powerful states makes it all the more important that smaller states uphold the principles on which the international system is based. Sri Lanka cannot credibly appeal to international law when it is threatened from outside while disregarding its own obligations within. Sri Lanka also needs to win the confidence of its own population that it is committed to justice and equality for all. Public opinion polls and community-level research have disclosed that ethnic and religious minorities are appreciative of the sense of greater security they enjoy under the present government from ethnic or religious extremists.
But a sense of security is not the same as the fulfilment of rights. As far as the Tamil people are concerned, the government has yet to deliver on several of its specific promises. These include the long-standing problems of missing persons, the release of political prisoners who have been members of Tamil militant organisations, and the return of land taken over for military purposes during the war. The issue of Buddhist statues and archaeological sites found on their properties which are then taken from their control continue to trouble them especially as they see no signs of resolution of those disputes. The issue of pastureland in the east of the country in Mylathamadu is particularly concerning to them as they see orders by successive presidents, both President Ranil Wickremesinghe and President Anura Kumara Dissanayake, being disregarded on the ground. The Mylathamadu pastureland dispute is where traditional Tamil dairy farmers have engaged in multi-year protests against the ongoing encroachment of their ancestral grazing lands by Sinhalese crop cultivators relocated under government development schemes.
The government’s failure to hold Provincial Council elections is particularly troubling. The provincial council system is the only one that can provide the Tamil people and other ethnic minorities the opportunity to wield political power and exercise a measure of self-determination in the areas in which they are the numerical majority. The continued postponement of Provincial Council elections therefore has consequences that go beyond an ordinary electoral delay. It deprives communities of an important constitutional avenue for democratic participation and power-sharing. The ethnic and religious minorities appreciate what the government is doing in the larger national interest, but they must not be made to feel that their special concerns are being ignored. The government cannot resolve Sri Lanka’s entire legacy of rights violations overnight. But it does need to demonstrate that it is willing to move forward on multiple fronts, not only on a few.

The emptying university: why are academics leaving?
by Hasini Lecamwasam
Brain drain in Sri Lanka is at an all-time high. The latest Human Flight and Brain Drain Index for 2024 shows that we are 16th of 175 countries on this count, and first in South Asia. That this is a crisis goes without saying. Brain drain affects all sectors, and is a huge strain on the resources of a developing country. Particularly in Sri Lanka, where considerable public investment is made in the moulding of professionals through the system of free education, this amounts to transferring the resources of poorer countries to richer ones with top migration destinations. It is, therefore, important to consider the push and pull factors behind skilled outmigration, specifically from the public university system of Sri Lanka, a key focus of the Kuppi column.
From frustration to exit
Several bitter realities in our crumbling public university system act as push factors in the migration decisions of academics. Many essays on this column have, over several years, attempted to highlight numerous aspects of this erosion. Perhaps, primary among them is the lack of adequate funding, which has debilitating ramifications for the system: very little investment is made in the up-keep of infrastructure (and even less in its expansion), resulting in serious constraints in accommodating growing batches of students and the wellbeing of the staff (particularly in regional universities); research funding is negligible, severely curtailing academics’ ability to effectively discharge their primary duty of teaching which should ideally be informed by their research (and the research of others, access to which is also, unfortunately, mediated by funding); a funding crunch also means a slash in (or greater constraints on) recruitments, increasing the workloads of academics, currently in service, and eating into the quality of their teaching and research.
What recruitments are done frustrate those with any faith in merit. As many of our interventions in this column have shown, recruitment processes are characterised by archaic selection criteria that place very little weight on a candidate’s postgraduate growth and the advantages of interdisciplinary training. Added to this is the general preference for ‘culturally compliant’ candidates who would not rock the boat too much. The combined effect is that those with the capacity and spirit to try out innovations in education are discouraged from joining or staying on in the public university system. Some, or many, of them may instead seek appointments abroad.
A thread that binds all of these problems together is pervasive hierarchy which, again, many interventions on this column have sought to highlight. It is the interest in preserving hierarchy that leads to the preference for alumni in recruitment processes. Hierarchy within universities can be particularly frustrating for younger faculty and women, who typically have to bear the brunt of the workload of their senior, often male, colleagues. In a context of funding, and, therefore, recruitment, restrictions, this translates into a disproportionate burden being placed on junior (usually female) faculty, seriously hindering their prospects of growing into successful academics due to the time constraints within which they have to operate. Junior academics, therefore, are more likely to look to educational institutions abroad for what they hope would be a different work culture that respects them more.
Ideological ruses
On top of these structural frustrations are also the workings of neoliberal ideology. For one, the nature of relations between the global metropole and peripheral countries like Sri Lanka largely dictates what is desirable and what is not. The apparent lifestyles of Western countries – from food to clothing, housing, appliances, and so on – have continued to lure people from the periphery with the promise of a ‘better’ life, alongside better career advancement opportunities. This, of course, masks much of the struggle that goes on behind the scenes to survive in Western societies. For instance, in most cases highly attractive public infrastructure such as roads, public transport, clean air, quality control of food, and so on belie the astronomical privatised costs of healthcare and education. Health insurance is usually mandatory and steep in most high-income settings, while even subsidised education (for which eligibility criteria are strict) creates a serious dent in household earnings. Of course, the happy images of glossy trams and gleeful international travellers don’t convey this.
A second ideological ruse is the myth of greater opportunities and recognition abroad. While there is no denying that local skilled sectors – be it higher education, health, civil service, or private white-collar positions – are replete with issues that inhibit merit-based professional advancement, the notion that things are fundamentally different in Western countries stems from an uninformed optimism. As is now increasingly known and discussed, Western labour markets are notoriously racialised, and equivalent skills are rarely treated as such. Instead, it is usually demanded that skilled migrants clear certain formal examinations in their host countries. In fields like medicine, this is followed by an interview that may also be racially prejudiced. Once these initial steps are cleared, remuneration reverts to square one irrespective of experience accumulated abroad, not to mention the many subtle aggressions, rejections, and trials one has to go through in the negotiation of everyday life. In the many cases where professional qualifications are used as leverage for a move abroad, sights are set on a better future for one’s children, which again is informed by the misplaced faith in greater opportunities and a lack of awareness of the factors outlined above. Needless to say, in the global swing to the Right, things have become even more challenging. In such a context, considering the few rare cases where skilled migrants live extremely comfortable lives as the norm becomes a dangerous misconception.
The two ideological pull factors mentioned above are complemented by a push factor, which has to do with a highly classed understanding of what a white-collar professional is due in their society. Many of these aspirations are clearly articulated in academic trade union action demanding separate quotas for school entry, increased fuel allowances, winning back the presently stalled vehicle permit scheme, salary hikes, and so on. While working people have every right to agitate for better material conditions, insofar as it remains unconnected to a broader movement for improving the conditions of the lot of the working class, it remains self-serving and very much within the class logic of capitalist society. Since these demands are articulated as a means of maintaining distinction, it is clear that they are not envisaged as part of a class movement. The frustration of not having these needs for distinction satisfied may push some to seek greener pastures abroad, at least financially, (perhaps as a means of social mobility based on it), only to be disappointed on most occasions.
What is to be done?
Addressing the systemic push factors listed above requires, first and foremost, greater allocations for free public higher education. This would immediately translate into more recruitments and less work per academic, and better research and teaching in the long haul. An increase in funding would also ideally lead to greater infrastructural investments, especially including improving the living conditions of those who work in regional universities amid untold hardships. Next, fairer, more creative, and, therefore, more effective recruitment policies are badly needed to attract talented individuals to university positions. Rather than carving out a ‘special category’ for academics to achieve this purpose, which is informed by a classed logic, this needs to be done through fundamental reforms in recruitment processes. Third, a persistent attack on the entrenched hierarchy within universities through internal reform is much called for. Reforming recruitment practices will go a long way towards addressing this. Measures should also be taken to introduce more stringent policies against SGBV (not to mention ragging, even though it is not directly connected to brain drain). Such measures would create a safer, fairer, and more attractive workplace, which would give more reasons for people to stay.
On top of greater allocations, we also need a transformation of our aspirations themselves if this situation is to change. That necessitates a kind of education capable of questioning the ‘paradise’ conception of Western societies, and lays bare their colonial material and ideological dimensions, in both their historical and contemporary manifestations. These colonial understandings of the ‘good life’, moreover, have devastating ecological implications for the planet, not to mention social justice. An education with the ability to transform this mindset would hopefully prove to be more than a mere path to social mobility, rather being a tool of social emancipation that renders mobility moot.

Kuppi is a politics and pedagogy happening on the margins of the lecture hall that parodies, subverts, and simultaneously reaffirms social hierarchies.

Friends favourite Suzi Croner returns for Oktoberfest 2026
Charming audiences in Switzerland as Suzi Flückiger, Sri Lanka’s own Suzi Croner is coming home… for a very special occasion.
The bubbly former frontline vocalist of 90s band Friends will take the stage at a popular venue in Colombo for Oktoberfest 2026.
Known in Europe for her country and classic hits, Suzi has remained a much-loved name back home. This will be a rare chance for local fans to see her live and celebrate the voice behind so many Friends memories.
Oktoberfest 2026 in Colombo promises an evening of live music, traditional Bavarian food and beer, colourful dirndls and lederhosen, folk dancing, and plenty of community cheer.

Suzi Croner (Flückiger)
Against this lively backdrop, Suzi will take the stage for a special solo set, featuring her own pre-recorded music. She performed at the event last year too, as a solo artiste, but a German band providing the music.
This year, however she says, it’s a different scene.
“The novel attraction will be the dancers from Germany — all girls, clad in German outfits,” Suzi said. She added that the event will also highlight the activities generally connected with Oktoberfest, which should generate a lot of fun and excitement for those who join her in Colombo next month.
Suzi has become a much-in-demand artiste in Europe, and has even performed Down Under, in Melbourne.
In Switzerland, where she has been based for the past 42 years, she continues to charm audiences with country and classic hits, performing at private events and community nights across Europe.
“My weekends are generally loaded with my work as a singer,” she said. “And I also play tennis three times a week, because I need to keep fit to entertain my audience in an active way.”
Her repertoire is made up mainly of Swiss, German and English songs.
And true to form, Suzi loves springing surprises.
“So watch out when you join me at Oktoberfest 2026, in Colombo!” she said.
