Benefits of green tea
Green tea is a type of tea that is made from Camellia sinensis leaves and buds that have not undergone the same withering and oxidation process which is used to make oolong teas and black teas.[1] Green tea originated in China, and since then its production and manufacture has spread to other countries in East Asia. Several varieties of green tea exist, which differ substantially based on the variety of C. sinensis used, growing conditions, horticultural methods, production processing, and time of harvest.
The health benefits of green tea
Is green better for you than black? Does it contain caffeine? Can it help ward off disease? Nutritionist Jo Lewin examines the dietary benefits of green tea. All types of tea, even your regular cup of builder’s, come from the Camellia sinensis plant. Green tea gets its name from the emerald green colour created when brewing unprocessed, unfermented tea leaves. With origins going back as far as 5,000 years, green tea is commonly drunk and widely grown in the Far East where the health properties are well regarded.
Different varieties of green tea
The difference between green and black tea results from the manufacturing process. Black tea undergoes fermentation which transforms its colour and flavour, whereas green tea remains unprocessed and retains its colour. Green tea is grown in higher altitudes, more specifically the mountainous regions of East Asia. Some green tea is still picked by hand, and it is thought that handpicked teas are less bitter and yield a sweeter, more robust taste. Other factors such as the climate and soil can also affect the flavour.
Sencha is the most popular of Japan’s green teas. There are numerous grades which can affect the price and quality. Sencha leaves are first steamed and then shaped. Sencha tea produces a clear yellow/green tea with a sweet, grassy but slightly astringent flavour.
Matcha is made from green tea leaves grown in the shade. The leaves have a higher chlorophyll content which makes them a vibrant green colour. To make matcha, the entire leaf is ground down into a powder. The powder is mixed with boiling water and gently whisked before being served. The flavour is light and sweet and so is now added to desserts and sweet drinks.
Green tea can be found as fresh leaves or in tea bags, frequently
blended with other flavours such as lemon, lime or ginger.When buying tea leaves, avoid older leaves. This is the same principle as with coffee beans. Allegedly, whole leaves are the highest grade and leaves that are older than four months are past their level of peak freshness. Once purchased and opened, keep leaves in an airtight container that can be resealed and store in a cool place to help slow down the reactions that can reduce the tea’s phytonutrient content and impact on flavour.
Nutritional highlights
There are many health claims surrounding green tea from a reduced risk of cancer to weight loss. The evidence to support these claims is largely inconclusive. Some of the health claims are based on ancient Eastern traditions, where green tea has been used to treat symptoms of disease for years. Because of the proposed benefits, many ‘health’ products now include traces of green tea. However, there is limited evidence to suggest these products are effective. If you are hoping to use green tea for medicinal purposes, make sure to consult your doctor first.
Green tea does have more health benefits than black tea which can be attributed to its lack of processing. Green tea is higher in protective polyphenols. The major polyphenols in green tea are flavonoids, the most active of which are catechins and epigallocatechin gallate (EGCG) which function as powerful antioxidants. Antioxidants are known to protect the body against disease and are an important part of a healthy diet. Antioxidants can be found in a range of fruits, vegetables and other unprocessed foods. As part of a balanced diet, green tea can be a good source of antioxidants.

How much caffeine does green tea contain?
Green tea does contain caffeine, although varieties and brands may differ. An equal quantity of green tea contains less caffeine than coffee (one cup of green tea contains approximately 35-80 mg compared to approximately 100-400 mg in the same size cup of coffee), but it can still act as a stimulant. As a result, some people find that drinking green tea increases energy levels, concentration and mood, but this effect may vary between individuals.
If you are sensitive to caffeine, it is advisable to limit the total number of cups of green tea you drink in a day. Too much caffeine can disrupt sleep patterns. If this affects you, try cutting back on caffeinated drinks after lunchtime.
Can green tea affect iron levels?
Like all types of tea, green tea contains tannins. Tannins can interfere with the absorption of iron so try not to drink tea with an iron-rich meal and leave at least one hour before drinking tea after an iron-rich meal.
Proven Health Benefits of Green Tea
Green tea is considered as one of the healthiest beverages across the world. This delightful and aromatic drink has tonnes of health benefits and can do wonders to enable a long and healthy life.
Green tea is more potent than any other tea simply because it is processed differently. Green tea is dried and steamed – this minimal processing leaves it with its green color, more antioxidants, nutrients and thus contributes to its wealth of benefits. For this reason, green tea makes for a daily cup full of fantastic health benefits:
Fights Allergies:
If you suffer from seasonal allergies, be it stuffy nose or itchy eyes, you might be surprised to learn that a cup of green tea may help you overcome your symptoms.

EGCG, the abundant antioxidant compound in green tea, may help stop your body from mounting an immune response to a wide range of allergens, including pollen, pet dander, and dust.
. Reduce Body Fat:
Green tea contains caffeine and a type of flavonoid called catechin, which is an antioxidant. Research suggests that both of these compounds can speed up metabolism, increase the amount of energy the body uses and decrease fat content of the body. The consumption of green tea as a weight loss strategy must be supplemented by other healthy weight loss methods, such as exercising and eating a healthy diet with plenty of vegetables. Green tea used alongside these methods may increase and enhance the positive results. Green tea is easily available online and offer a plethora of flavors to chose from.

Nanda Malini Ascocenda: A flower that carries the name of a legendary voice
By Ifham Nizam
A flower named after one of Sri Lanka’s most celebrated voices has become a unique tribute to the country’s cultural heritage, with the Nanda Malini Ascocenda orchid carrying the name of veteran singer Dr. Nanda Malini.
The orchid was named in honour of Nanda Malini, recognising her outstanding contribution to Sri Lankan music and culture. She is among the country’s most acclaimed singers, with a career spanning several decades and a repertoire deeply rooted in Sri Lankan social and cultural experiences.
The striking illustration, released by the Ministry of Environment on August 21, features the veteran singer surrounded by colourful orchids and musical notes, bringing together two important elements of Sri Lankan identity — the country’s rich natural heritage and its musical tradition.
The Nanda Malini Ascocenda is particularly significant because it represents an unusual meeting point between art and nature. Orchids have long been associated with Sri Lanka’s botanical wealth, while the naming of individual hybrids after distinguished personalities provides a lasting link between the country’s natural and cultural heritage.
According to published accounts, the Nanda Malini Ascocenda was named in 2004 in recognition of the singer.
A recent profile described her as possibly the only Sri Lankan artiste to have an orchid named after her by the Orchid Circle of Sri Lanka.
Nanda Malini’s contribution to music has been recognised through numerous awards. She has also performed internationally and remains one of the most recognised figures in Sri Lankan music.
Her association with songs reflecting social realities, human emotions and national identity has given her a special place in the country’s cultural landscape.
The orchid, therefore, represents more than a botanical curiosity. It is a living tribute to an artiste whose voice has accompanied generations of Sri Lankans.
The Ministry of Environment’s presentation also serves as a reminder that conservation is not limited to forests, wildlife and ecosystems. Sri Lanka’s natural heritage is closely intertwined with its history, culture, art and the people who have enriched the nation’s identity.
As the colourful blooms of the Nanda Malini Ascocenda evoke the beauty of Sri Lanka’s orchid heritage, the name attached to them ensures that the contribution of one of the country’s most distinguished musical voices continues to live on in an entirely different form — through nature itself.

The Best of Malkoha celebrates half a century of Sri Lankan ornithological writings
By Ifham Nizam
The launch of The Best of Malkoha: Half a Century of Ornithological Writings marked a significant milestone in Sri Lanka’s birdwatching and conservation history, as the Field Ornithology Group of Sri Lanka (FOGSL) celebrated its Golden Jubilee at the Faculty of Science, University of Colombo.
The book, drawn from five decades of writings published in Malkoha, the FOGSL newsletter, brings together a rich record of observations, discoveries and experiences that helped shape modern field ornithology in Sri Lanka.
The launch formed part of FOGSL’s first-ever Founders’ Day, held on August 22, a date chosen to coincide with the 76th birthday of Vidyajothi Emeritus Professor Sarath Kotagama, one of the Organisation’s founding figures and its enduring source of inspiration.
The occasion brought together academics, conservationists, naturalists, birdwatchers, students, young birders and members of FOGSL, reflecting the broad community that the organisation has cultivated since its establishment in 1976.
Biodiversity expert Dr. Rohan Pethiyagoda, delivering the Golden Jubilee Founders’ Day Oration, used the occasion to reflect on five decades of biodiversity research and conservation in Sri Lanka, while paying tribute to Professor Kotagama and the role played by FOGSL in taking birdwatching beyond a small circle of specialists.
Pethiyagoda said the organisation’s greatest achievement had been its ability to make knowledge of birds and nature accessible to ordinary people.
He recalled how, in the early 1990s, Professor Kotagama had proposed producing an affordable field guide so that birdwatching would no longer be restricted by the high cost of existing publications.
That resulted in the publication of A Field Guide to the Birds of Sri Lanka in 1994, which Pethiyagoda published and which subsequently became a bestseller.
The collaboration later produced Sri Lanka Kurulu in Sinhala, making serious bird identification and knowledge available to an even wider audience.
Pethiyagoda recalled a particularly emotional encounter that demonstrated the lasting impact of that work.
During a recent visit to Talangama to accompany Australian birdwatchers, he encountered two boys, aged around 12 and 14, carrying a battered copy of Sri Lanka Kurulu and using it to identify birds.
“I just started crying,” Pethiyagoda said, describing the moment as evidence of how knowledge had been passed from one generation to another.

He said the achievements of the past 50 years should not be underestimated. Sri Lanka has witnessed major advances in health, education, infrastructure and conservation, while the country’s protected-area network has expanded considerably.
At the same time, however, he warned that biodiversity research and conservation continue to face serious institutional challenges.
Pethiyagoda pointed to habitat fragmentation, climate change, inadequate scientific research and restrictions on field research as major challenges facing the next generation of conservationists.
He said climate change would increasingly force species to move towards cooler, higher elevations, but fragmented habitats could prevent them from making such movements.
“Our challenge now is to connect up those little fragments so that plants and animals can migrate across these landscapes,” he said, stressing the importance of restoring ecological connectivity.
He also called for greater investment in ex-situ conservation for species facing extinction and urged the establishment of conservation facilities across Sri Lanka’s different climatic zones.
Pethiyagoda placed particular emphasis on citizen science, arguing that Sri Lanka possessed an enormous reservoir of public enthusiasm for biodiversity.
He noted that more than 20,000 Sri Lankans were now involved in citizen science through platforms such as iNaturalist, with Sri Lankan users generating significant biodiversity data.
“The appetite for science, the appetite for conservation, for exploration, for discovery is there in the people,” he said.
Pethiyagoda also paid an emotional tribute to Professor Kotagama, describing him as the constant force behind much of Sri Lanka’s modern conservation movement.
“In future generations, we will talk of conservation in this country as before Kotagama and after Kotagama,” he said.
He also acknowledged Professor Kotagama’s wife, Namali, for being the “bedrock” of his household and for supporting his decades-long contribution to conservation.
The Golden Jubilee celebrations also looked back at the origins of FOGSL.
The Organisation was founded on October 10, 1976, when four passionate bird enthusiasts—the late P. B. Karunaratne, Professor S.U.K. Ekaratne, Professor Sarath Kotagama and Rex I De Silva —came together with a shared objective of making birdwatching accessible beyond the relatively exclusive group that had traditionally dominated the field.
FOGSL was subsequently formally recognised by the University of Colombo and developed as a platform bringing together birdwatchers, researchers, students, educators and nature enthusiasts.
Its philosophy was simple: one did not need an academic qualification to become a member. Enthusiasm, careful observation, recording and sharing knowledge were enough.
That principle continues to define the Organisation.
FOGSL has since become Sri Lanka’s BirdLife International partner and has played an important role in bird research, conservation, environmental education, field studies, school programmes and citizen science.
Its work has extended from research on endemic birds and migratory species to biodiversity monitoring, conservation education and programmes aimed at children and young people.
Speaking at the event, FOGSL President Professor Nihal Dayawansa said the organisation’s founding vision remained relevant even after half a century.
The Organisation, he noted, was created not simply as a birdwatching club but as a platform through which people could study and conserve Sri Lanka’s birds while inspiring the wider public to appreciate nature.
The Founders’ Day itself was described as an opportunity to honour those who established and shaped the Organisation while celebrating the contribution of generations of members.
Professor Mayuri Wijeyasinghe, Head of the Department of Zoology and Environmental Sciences, said FOGSL had given ornithology a new meaning in Sri Lanka by taking birdwatching beyond an elite community and making it accessible to ordinary people and schoolchildren.
She noted that Sri Lanka, as a tropical island with a remarkable diversity of birds and a high level of endemism, had a special responsibility to understand and conserve its avifauna.
The Dean of the Faculty of Science, Professor I.M.K. Fernando, meanwhile, said that although his own field was physics, he recognised the common foundation shared by all branches of science—curiosity.
He congratulated FOGSL on reaching 50 years and praised its contribution to research, education, student development, wetland conservation, public awareness and science-based advice on development projects.
“The work goes far beyond publishing,” he said, noting the Organisation’s lectures, school programmes, research projects and conservation initiatives.
He also paid tribute to Professor Kotagama, describing him as a legend whose influence had extended well beyond ornithology.
Professor Kotagama, speaking after receiving tributes from colleagues and friends, said the Organisation’s foundations had been laid with a belief that people could make a difference.
He stressed the importance of taking decisions based on scientific knowledge and criticised excessive bureaucratic barriers that, in his view, prevented scientists from carrying out important field research.
Reflecting on his own period as Director of Wildlife Conservation, he said he had sought to transform the Department into a scientific institution.
“For me and for us who were working in the Mahaweli environment programme at that time, we knew that if not for science, you cannot go forward in conservation,”
Professor Kotagama said, stressing that conservation required both natural and social sciences.
He recalled the challenges faced by the Department, including inadequate staffing structures and poor career progression for wildlife officers, and said efforts had been made to introduce a more professional and scientifically grounded system.
The 50-year journey of FOGSL is closely intertwined with the development of modern field ornithology in Sri Lanka.
From the early days when birdwatching was largely confined to a small group of specialists, the Organisation helped create a culture in which students, schoolchildren, amateur birdwatchers and citizen scientists could contribute to the understanding of the country’s biodiversity.
The launch of The Best of Malkoha, therefore, served as more than the unveiling of another publication. It was a record of that transformation.
The writings collected in the volume represent five decades of observations and experiences, documenting how Sri Lankan field ornithology evolved through the work of generations of birdwatchers, researchers and conservationists.
As theOorganisation enters its next half century, the message emerging from the Golden Jubilee celebrations was clear: the future of conservation will depend not only on institutions and scientists but also on an informed and empowered public.
FOGSL’s enduring motto—”Once a member, always a member”—perhaps best captures that legacy: a lifelong connection with birds, nature, scientific observation and the responsibility to protect Sri Lanka’s extraordinary natural heritage.

Heart that beats for humanity
Dr. Rajitha de Silva
By Zanita Careem
Dr. Rajitha Y. de Silva, Consultant Cardiothoracic Surgeon and Consultant at Sri Jayewardenepura General Hospital, has built a distinguished career around one of medicine’s most demanding discipline – surgery of the heart. With his expertise, precision and pioneering spirit, he has become closely associated with the advancement of Minimally Invasive Cardiac surgery in Sri Lanka. He joined Sri Jayewardenpura General Hospital in 2013 and is today recognised as a pioneer of Minimally Invasive Cardiacs procedures in the country.
He is particulary recognised as a pioneer of mimimallyinvasive surgery in Sri lanka,with experience in procedures including minimally invasive coronary surgery and mitral valve repair. He is recognition as a leading figure in the advancement of modern cardiac surgery in the country. With years of specialised training and experience behind him, Dr de Silva has built a reputation in cardiothoracic surgery while remaining deeply conscious of the human story behind every patient who enters the operating theatre. For him, the beating heart is more than an organ to be repaired – it represents a life, a family, a future and a second chance.
His commitment to patients extends well beyond the operating theatre. Having witnessed the financial hardships faced by heart patients who desperately needed surgery but could not afford it. Dr de Silva, together with Senior Cardiologist Dr. Ruwan Ekanayake, co-founded the Heart to Heart Trust Fund.
The initiative was created with a powerful objective, that no patient should be denied life saving cardiac treatment simply because of financial difficulties.
Perhaps one of the most striking aspects of Dr de Silva’s personality is that his concern for patients does not end when the operation is over. His vision has included creating initiatives that make the difficult journey of cardiac patients more humane, giving them encouragement, dignity and hope during a period when they are often at their most vulnerable. Abayadhana was born from a simple but powerful conviction that every patient deserves a chance to live.
Through the Abayadhana programme, he represents his compassionate approach to caring for people who need not only medical attention, but also understanding, encouragement and support. What makes this initiative particularity meaningful is the personal commitment behind it. It reflects his belief that healing is not only about medicine, but about reaching out to people when they are most vulnerable.
Away from the intensity of the operating theatre, Dr. Rajitha de Silva finds another kind of joy – his passion for cricket over the years; he has taken the field in numerous matches, playing alongside and against many well known personalties.
Dr. Rajitha de Silva’s journey is guided by compassion and success anchored in humanity. From pioneering milestones in cardiac surgery to the Heart to Heart Trust Fund and the Abayadhana initiative, he has continued to give back to the people whose lives he touches. His love for cricket, his warmth and generosity reveal the heart behind the healing hands.
A surgeon by profession, a humanitarian by choice and a cricketer by heart, Dr. Rajitha’s greatest legacy may not be measured only by the operations he has performed, but by the lives he has changed, the hope he has restored and the hearts he has touched.
The trustees of the Heart to Heart Trust Fund stand united behind the mission of saving lives and giving hope. Their collective commitment helps turn the Trust’s vision into meaningful support for patients and families in need
The Executive Director, Heart to Heart Trust Fund, Shanti Fernando, plays a hands on role in turning the Trust’s vision into action, coordinating efforts, and bringing hope where it is needed.
Behind Dr. Rajitha de Silva’s demanding life is his wife, Dr. Arunie, and children, who has been his strength and support.
