A German study revealed a possible role for green tea in reducing the incidence of colon cancer in mice, a result that may have applications in humans as well.
Doctors Thomas Zuefferlein and Julia Stenigl at the German University Hospital Ulm examined the effect of green tea on mice, as it contains “catechins”, which have antioxidant properties.
The researchers tested the effect of catechins on mice suffering from a benign genetic change present in humans with colon cancer, by giving the mice green tea to drink instead of water.
And when a gastroenterologist at the University Hospital in Ulm, Prof. Thomas Zuverlein, examined the results, he noticed a decline in the percentage of benign tumors she had.
These positive results of the effect of catechins on mice with benign tumors prompted German researchers to test them on patients who have non-malignant tumors as well, as these usually have a higher incidence of malignant tumors in the future.
Experts advise individuals with colon polyps to take two capsules of green tea daily (equivalent to the effect of five cups of it) as a measure that may help reduce its progression and metastasis.
And confirms the participating member of the study d. Julia Stengel, from the Federal Center for the Industry of Medicines and Medicinal Materials, said that despite the effective role of catechins in green tea, it contains a stimulant caffeine, which may not be suitable for many such as hypertensive patients, which prompted German doctors to develop green tea capsules without caffeine.
Yulia points out that green tea cannot become a drug for treating cancer that develops through long-term stages, which means that it can be reduced through preventive methods, including drinking green tea.
And Dr. Zoifferlin believes that the preventive effect of green tea is not limited to colon cancer, but also to prevent other types of cancer.
