What’s the difference between regular tea, and herbal tea? Also what exactly is herbal tea? Like green tea?

Lately, I’ve been trying to drink more tea than coffee. I found a chamomile tea at the dollar store that I like. It helps me to unwind in the evening. I bought a Celestial Seasonings (I think that is the brand) blueberry tea. I’m not sure how i like it yet. It is a different taste. What kind of tea do you like? Is all tea basically the same, or are more expensive brands better tasting and better ingredients? I like herbal tea versus the black tea.

I was suppose to get my period last week and know am going on vaction this week it usally come when am going some where excited then i end not having fun becuz it hurts so much

My son is 19 months. He has a real bad viral infection and has been coughing, sneezing, etc. I made a little peppermint herbal/caffeine free tea and he was sipping on it. I thought it may help soothe. Just didn’t know if there’s some crazy thing in herbal tea that isn’t good for babies?

I have anxiety, and was wondering if this herbal tea (caffeine free) was good for relieving tension. Is lemongrass, lemon peel, or ginger root supposed to be relaxing? Thanks (:
