7. Sterilizing and curing dermatophytosis.
Tealeaf contains a great deal of tannin, which has a strong sterilizing effect, especially to filamentous fungus, which causes dermatophytosis. Hence, if people who suffer from dermatophytosis persist in washing their feet with concentrated tea juice every evening, they will get rid of the disease without using any medicine. But these people should persevere in doing so, because one will see no obvious effect within a short period. Better use green tea, since the fermented black tea contains less tannin.
