My friend gave me a box of Korean red ginseng tea last week. It's a powder that's mixed with hot water, so it's like instant tea.
Not only does it taste very good, but it's also like an energy drink. I drink it in the morning and it has the same affect as coffee, except that I don't get jitters from it. I feel very positive too, I don't know if the ginseng has to do with it. I do add some honey though because the tea is not sweet on its own.
