Well, currently, I drink this strange concoction of boiled sibukaw (sheepeye) wood, which only grows in the Philippines. To my grandmother, it clears the body and gets the blood going.
I feel physically more able drinking sibukaw. I would love more, but again, it only grows in the Philippines that I know of, lol. I feel mentally clarified and purified drinking it.
If not sibukaw, then a light flavoured tea, such as chamomile or Japanese green tea. Strong flavours make me feel muddled sometimes, lol.
