As far as I remember, herbal teas are allowed. If you can find some of these as liquids and drink them as teas, I see no harm in it. Purity aside, it seems that Burroughs would not have allowed herbal teas if they would somehow throw off the balance of the program.
I'd leave out the garlic, wheatgrass and DE, as those are more like foods than herbals. The rest are just herbals and I don't see where they would hurt.
Keep in mind, though, that with nothing to stop them, they will likely just go straight through your body and do you no good. You will just be flushing them out. If you are going to do them as tea, drink it at night so it will stay with you longer.
I know that the purists will bash me for saying this, but it just makes sense to me.
