Depends on what your goal is. Herbal tea doesn't have a substance called theine, which is something like caffeine. S, if you drink tea to relax before going to bed, herbal tea might be the better option. Besides that, I think drinking tea in the evening is more about the ritual and giving your mind and body a heads-up that you are almost going to bed. When you think about it that way, any tea and relaxing ritual is better than no tea.
