hmm?
green n black tea comes frm same plant leh..but black tea undergoes
more processing and crushing
this makes the 'good stuff' available.. like for tomatoes, after
being proceesed, they have higher lycopene levels which will be
much easilly absorbed in our bodies. 
Better to drink processed tomato juice than naturally
squeeze one.
You may have a point it have higher content, but the thing is
whether its available or not. Same like spinach.....have lots of
iron, but we humans can only take about 13-17% of it...better off
drinking milk
