Waste tea leaf extract offers hope of lung cancer treatment after ‘accidental’ discovery
Extract from waste tea leaves may be the key to a treatment for lung cancer, according to researchers from Swansea University and two Indian universities who were creating microscopic biomarkers called “quantum dots” to improve the detection and imaging of tumours.
According to The Independent, "In an effort to increase the luminosity of the quantum dots the team introduced tea leaf extract to the particles, but instead of increased fluorescence the team found the plant had unexpectedly reduced the size of the quantum dots considerably, and also that they destroyed 80 per cent of the lung cancer cells they were exposed to."
“It was very surprising for us,” researcher Dr Sudhagar Pitchaimuthu told The Independent. “We made a systematic laboratory-based analysis with lung cancer cells, and we got an impressive result. And when we increased the quantum dot concentration we saw a corresponding fall in cancer cells.”

June 6, 2008 -- “The health benefits of green tea have been widely promoted and it has been known for some time that EGCG can alter the structures of amyloid plaques associated with Alzheimer’s disease," said David Middleton, professor, Lancaster University. “Our results show that this intriguing compound might also be effective against the types of plaques which can cause heart attacks and strokes.”
The team is now working on ways to deliver an effective amount of EGCG without having to overdose on green tea.
