Yes, I would imagine that the teas would break down gluten.
Try to look for digestive aids besides the tea as well, such as:

Like I had mentioned, I take a digestive aid and I am completely fine now, I have much more energy than I used to (and this was one of my main problems before- a lack of energy) and a clarity of mind, I also don't feel so groggy and tired after eating grains.
