1. Don't let tea leaves swim inside the hot/warm water all the time. The longer the leaves stayed in the water, the more caffein they produce. Take out those leaves after a short moment, and you can use back the same leaves to boil another few cups of me.
2. Not too hot! 80 degree celsus known to be the best temperature for me. Too hot will cause direct damage to the tea leave, hence, no more vitamin.
3. Sit back and relax. Drink me in a peaceful mind, and I bring more calm to your world.
