KANDY – Scientists of the Peradeniya University have produced a herbal immunity enhancer capable of combating bacteria and any kind of virus, including the COVID-19.
Introducing the product, named as Prana, to the media, at the Department of Veterinary Pathobiology of the University of Peradeniya, on Saturday, Senior Professor and Head of the Department Prof Jayantha Rajapaksa said that the immunity raiser had been produced from local herbs and spices such as cardamom, cinnamon, pepper, ginger, thalisa pathrra, and una kapuru.
The tests conducted by the Department had proven that the product could boost primary immunity in humans against viruses, Prof Rajapakse said, adding that increasing immunity against an identified virus was known as enhancing the secondary immunity, which ensures protection from only identified viruses. Vaccination against an identified virus is increasing secondary immunity. The immunity booster produced by the university could ensure the enhancement of primary immunity thereby be a sure protection against any variant of the COVID-19 virus and other harmful bacteria, he said.
Senior Prof Rajapakse said: “We have conducted two main researches on this product which could be used by people as a drink. The first research has confirmed that there are no elements harmful to humans in the drink while the second confirmed an increase in immunity. Usually, every human gets primary immunity from his parents and it is in his or her genes. Importance of boosting primary immunity in the face of a virus, such as COVID-19 which was evolving fast to produce new variants, is very high.”
Senior Professor Rajapakse said that the testing of the product had taken three months, and the product could be marketed as it is safe and it could counter any virus including COVID-19.
Ayurvedic Dr. Pradeepa Dissanayake (BAMS, Colombo) said that the primary immunity enhancer had been endorsed by the Ayurvedic Department and could be used against diseases in the respiratory system. It could be prescribed for fever, common cold, running-noses, headache and cough, she said.

Environmentalists warn Sri Lanka’s ecological safeguards are failing
Sri Lanka’s environmental protection framework is rapidly eroding, with weak law enforcement, politically driven development and the routine sidelining of environmental safeguards pushing the country towards an ecological crisis, leading environmentalists have warned.
Dilena Pathragoda, Managing Director of the Centre for Environmental Justice (CEJ), has said the growing environmental damage across the island is not the result of regulatory gaps, but of persistent failure to enforce existing laws.
“Sri Lanka does not suffer from a lack of environmental regulations — it suffers from a lack of political will to enforce them,” Pathragoda told The Sunday Island. “Environmental destruction is taking place openly, often with official knowledge, and almost always without accountability.”
Dr. Pathragoda has said environmental impact assessments are increasingly treated as procedural formalities rather than binding safeguards, allowing ecologically sensitive areas to be cleared or altered with minimal oversight.
“When environmental approvals are rushed, diluted or ignored altogether, the consequences are predictable — habitat loss, biodiversity decline and escalating conflict between humans and nature,” Pathragoda said.
Environmental activist Janaka Withanage warned that unregulated development and land-use changes are dismantling natural ecosystems that have sustained rural communities for generations.
“We are destroying natural buffers that protect people from floods, droughts and soil erosion,” Withanage said. “Once wetlands, forests and river catchments are damaged, the impacts are felt far beyond the project site.”
Withanage said communities are increasingly left vulnerable as environmental degradation accelerates, while those responsible rarely face legal consequences.
“What we see is selective enforcement,” he said. “Small-scale offenders are targeted, while large-scale violations linked to powerful interests continue unchecked.”
Both environmentalists warned that climate variability is amplifying the damage caused by poor planning, placing additional strain on ecosystems already weakened by deforestation, sand mining and infrastructure expansion.
Pathragoda stressed that environmental protection must be treated as a national priority rather than a development obstacle.
“Environmental laws exist to protect people, livelihoods and the economy,” he said. “Ignoring them will only increase disaster risk and long-term economic losses.”
Withanage echoed the call for urgent reform, warning that continued neglect would result in irreversible damage.
“If this trajectory continues, future generations will inherit an island far more vulnerable and far less resilient,” he said.
Environmental groups say Sri Lanka’s standing as a biodiversity hotspot — and its resilience to climate-driven disasters — will ultimately depend on whether environmental governance is restored before critical thresholds are crossed.
