Herbal research, the scientific method and Oncoceuticals

Where does the rigours of the scientific method come into existential conflict with the contextual and situational reality of the terminal cancer patient? If that sentence sounds verbose gibberish, let me ask it simply. Does it make much difference to terminal cancer patients if they try a herbal concoction’ in their last days, in some fervent hope that it could give them relief from the terrible adverse effects of Western onco-medicines?

“After nearly 17 years of continuous research since 2008, the Institute of Biochemistry, Molecular Biology and Biotechnology of the University of Colombo has successfully developed a nutrient-based drug capable of destroying cancer cells. The breakthrough was led by Professor Sameera R. Samarakoon and his research team, who discovered that a combination of five medicinal plants - Vernonia zeylanica, Nigella sativa, Hemidesmus indicus, Leucas zeylanica, and Smilax glabra - has the potential to kill cancer cells. This discovery marks a significant step forward in cancer research, highlighting the value of traditional medicinal plants in modern scientific innovation.”

“A locally developed nutraceutical targeting cancer stem cells is expected to generate around two million U.S. dollars in export revenue for Sri Lanka by 2027, according to Prof. Sameera R. Samarakoon of the Institute of Biochemistry, Molecular Biology and Biotechnology, University of Colombo. The product, launched three years ago, has already gained traction among Sri Lankan consumers, with positive feedback on its effectiveness in improving quality of life. While emphasising that it is not a drug, Prof. Samarakoon said the nutraceutical was developed as an alternative approach in the fight against cancer.”
