During twenty weeks Japanese specialists were sprinkling with green tea ethanol solution the bedding in the cages for 9-week-old female mice. The bedding was soaked with the tea solution, and at first, it was changed daily, but starting from the fourth week of the experiment — thrice a week. Lab tests of the tea mice and the mice of the control group have demonstrated that the tea mice have a lower level of 8-hydroxydeoxyguanosine in urine and higher antioxidant properties of blood serum. In addition, even if mice were subjected to X-ray irradiation, an increase in the level of 8-hydroxydeoxyguanosine in their urine was suppressed by the aroma of green tea.
Do not repeat this at home, since it wasn’t a plain green tea aroma used in the experiments. The source of the fragrance was a steam extract condensate of green tea leaves in ethanol (commercial name — Green Breath®), diluted 5-fold with distilled water.
