Published

on

A study conducted by Dr Sameera Samarakoon of the Institute of Biochemistry, Molecular Biology and Biotechnology, University of Colombo, with renowned Food Scientist Dr. D. B. T. Wijeratne, has found that consuming green tea with gotu kola (Centella asiatica) as a mix could produce many health benefits. Gotu kola enhances the antioxidant, antiviral and immune-boosting properties of green tea.

Pegged as the herb of longevity, gotu kola is a staple in traditional Asian medicinal practices and green tea is one of the most popular health beverages around the world. Health benefits of green tea are well known and it is commonly consumed by many people owing to its antioxidant properties, reduction of obesity, prevention of cancer, reduction of blood pressure, etc. Similarly, in ancient medicinal practices in India, Japan, China, Indonesia, South Africa, Sri Lanka, and the South Pacific, the health benefits of gotu kola is well known. Modern laboratory tests have confirmed that the gotu kola has antioxidant properties, beneficial effects to the liver, skin protection and improving cognitive function and memory power.  All health benefits of both could be obtained when consuming a mixture of green tea and gotu kola, Dr Samarakoon said.

He said that gotu kola should not exceed more than 20 percent of the mixture due to reduction in acceptability as a beverage.

He said that green tea and gotu kola could be recommended as herbal beverages.

Dr Wjieratne said that previous studies had confirmed that consumption of gotu kola had a positive effect on improving liver health especially with regard to the most common type of primary liver cancer, Hepatocellular carcinoma, fatty liver and liver cirrhosis.  Recent research has also pointed out that gotu kola could help reduce blood pressure and cardiovascular diseases including stroke, myocardial infarction and coronary artery disease. Pharmacological studies have reported that the gotu kola extract can regulate the central nervous system activity and enhance cognitive function in the brain.

Dr Wijeratne pointed out that the health benefits of green tea have been well known around the world. Compared to gotu kola there was more scientific research with regard to green tea’s health benefits. Green tea is rich in catechin, polyphenols, particularly Epigallocatechin gallate (EGCG).  The EGCG is a powerful antioxidant which kills cancer cells without harming the normal cells. This compound is also effective in lowering LDL cholesterol levels, inhibiting the abnormal formation of blood clots and reduction of platelet aggregation. In addition, it has been found that green tea extract is a promising source of natural antioxidants that has been effectively utilized to enhance the antioxidant properties, Dr Wijeratne said.

He said that obesity had been identified as the major cause of a number of diseases, including coronary heart diseases, hypertension, non-insulin dependent diabetes, pulmonary dysfunction, osteoarthritis and certain types of cancer. Tea catechin, especially EGCG, appears to have an anti-obesity and diabetes effect. Green tea was also seen as a natural herb that can enhance energy expenditure and fat oxidation and thereby induce weight loss, Dr Wijeratne said, adding that consumption of a combination of two herbals could provide plentiful health benefits.

Herath

Foreign Affairs, Foreign Employment and Tourism Minister Vijitha Herath yesterday (05) told a media conference at his Ministry that the UN should deal with the US for violating international law.

Herath, who is also a senior member of the ruling National People’s Power (NPP) party’s National Executive Council, in addition to being a member of the JVP politburo, emphasised that member states couldn’t violate UN Charter and international laws.

The Minister said so when The Island sought the government’s position on the abduction of legally elected Venezuelan President Nicolás Maduro and his wife in a lightning raid carried out amidst heavy air strikes on that country. We raised the issue at hand pointing out that there were persistent allegations regarding US and Indian interventions in the 2022 regime change operation here and that the NPP finalised defence agreements with Washington and New Delhi.

Minister Herath said that Sri Lanka backed the ongoing UN Security Council bid to deal with the developing situation in Venezuela.

Herath was flanked by Deputy Foreign Minister Arun Hemachandra and Deputy Tourism Minister Prof. Ruwan Ranasinghe.

Minister Herath said that the UN Security Council was scheduled to take up this issue today. The US is one of the five members of the UN Security Council.

In terms of the UN Charter, UN members are to refrain from the “use of force” against the territorial integrity or political independence of any state. Another permanent member of the UN Security Council, France, broke ranks with the Western block to condemn US action. France unequivocally declared that the US operation was a “violation of sovereignty.

Minister Herath didn’t respond to the query whether he discussed the issue at hand with President Anura Kumara Dissanayake.

While pointing out that Sri Lanka had been subjected to foreign interventions, The Island sought the position the JVP in respect of US President Donald Trump threatening to move against Mexico, Cuba and Colombia as the party always took a strong stand against US actions. Declaring that his response would be for the government and not the JVP, Minister Herath said that there was a way to deal with situations through the UN.

Minister Herath strongly defended recently signed agreements with India and US pertaining to defence. Stressing that both agreements were beneficial, Minister Herath pointed out that they weren’t defence agreements but security cooperation arrangements.

The US and Sri Lanka signed a Defence Memorandum of Understanding (MoU) in November 2025, formalising defence cooperation under the State Partnership Programme (SPP) with the Montana National Guard. The MoU with India was signed in April, 2025. It was among seven MoUs.

Referring to devastating Cyclone Ditwah, the Minister said that India provided material support under the MoU signed in April whereas the US provided 10 helicopters to the SLAF recently.

Responding to a query on US-Sri Lanka tariff negotiations, Minister Herath said that about 95% of the negotiations have been finalised.

At the onset of the briefing, Minister Herath and Deputy Ministers Prof. Ranasinghe and Arun Hemachandra explained how the tourism sector and expatriate Sri Lanka work force contributed to the national economy.

Referring to Central Bank figures, they declared that tourism had brought in USD 3.2 bn whereas expatriate workers contributed USD 7.19 bn up to November last year. Once the Central Bank made available December figures it could reach USD 7.8 bn, they said. Tourism and expatriate work force together brought in as much as USD 11.6 bn, they declared, expressing hope 2026 would definitely be better.

Although the devastation caused by Cyclone Ditwah caused concerns that it may cause a significant drop in tourist arrivals, a steady flow of visitors paved the way for a comfortable 15% increase in arrivals by end of 2025, they said.

Minister Herath said that the government was happy that the country recorded the highest number of tourist arrivals this year.
