Hi Don't Microwave the Bark just your water and let the bark sit in the hot water while on your trip... Don't want to destroy the nutrients in the bark... Check out http://www.dinapharm.com
I used to get the tea and while I still have a lot from my last order, they sent me an new email inregards to a capsule which is supposed to be better then the tea.
Any way I will stick to the tea as I have seen other glucose come down and stay down.
