If I make some bulk herbal tea and keep it in a plastic bottle /or maybe glass bottle is better?/ for several days up to a week to use it in the office, will that damage the active ingredients in any way. In particular I have in mind green tea, mate tea and chamomile.
I also have a question about the chamomile tea itself. I like it a lot, when taken consistently for some time @ 3-4 cups a day, I start feeling its effect as tonic for the body and relaxant for the mind, which for me is close to amazing /given also absolute absense of side effects/. After realising its effect I did some research on the internet to dig some more info on it. Not much on the scientific side though, and I read in a few sites that regular use in the long-term is not recommended, but the reason why was not indicated, anyone happens to know more about that?
