What's the goodness of herbal tea ( mint, anis seeds, or vervain for example) sugar-free?

For enjoyment: Regular teas and typical herbal teas, made from usual tea leaves, are for people to enjoy. The caffeine level is usually low, so teas are not too stimulating. A tea-drinker can try different teas and decide for herself what she likes most. Flavoring additives like mint or anise are in the teas in small amounts, so should not have a noticeable medicinal effect. Avoid adding too much sugar to tea.
