The effects of ten so-called health teas on mice and isolated rat hepatocytes were examined. After seven oral treatments of mice with 1000mg/kg/day of lyophilisates of each sample, thymus and spleen weights, respectively were significantly decreased by tencha and banabacha. Histological examination revealed no adverse effects on these organs. However, red and white blood cell counts were significantly decreased by treatment with these two teas.
With respect to the effects on isolated rat hepatocytes, lyophilisates of all samples caused dose-dependent decreases in cellular glutathione content, and, with two of them (tencha and banabacha), cell viability decreased substantially (to less than 60% of control value) at the highest dose tested (5000ppm).
