What is the procedure to extract the caffeine from tea?
The commercial process for removing caffeine from tea is fairly complex, however, according to my Chinese medicine doctor, if you pour boiling water over your tea (leaves or bagged) leave it for 20 - 30 seconds, pour out the "first" steep and re-fill your cup/pot with more boiling water. The resultant tea will be greatly reduced in its caffeine content.
