Will my toads benefit from the antioxidants in green tea if I have them bathe in cold green tea?

Note: Toads do NOT drink with the mouth. They absorb through the skin. Therefore a toad sitting in brewed green tea which has been cooled to room temperature they will in effect be drinking the green tea.

I can’t imagine in the wild toads would have access to green tea so I doubt sitting in cold green tea would benefit them at all and may well harm them.
