I've had to lay off caffeine and I'm pining for strong tannic black tea. It is actually the dark, bitter tannins I miss. Currently, I'm drinking a roasted dandelion root tea but it lacks body. I believe oak leaves have tannins so when I find some is it okay to just rinse them off and steep and drink? I would appreciate learning about substitutes.
Too slow for those who Wait,
Too swift for those who Fear,
Too long for those who Grieve,
Too short for those who Rejoice,
But for those who Love,
Time is not.

I like siberian tea (Bergenia crassifolia). You can collect the died off leaves (even in winter). They have a nice aroma and pleasant tannin. I read the fresh leaves are more adstringent tannic, but never tried those.
