Herbal teas are not actually produced from tea leaves like white, green, oolong and black teas. Herbal tea, often called an herbal tisane or herbal infusion, is generally made from dried fruits, herbs, even flowers. They can be brewed as tea leaves or blended with other types of tea to create an aromatic and flavorful cup of tea that is caffeine free.
There are typically three categories of herbal teas based on their main ingredients. First, rooibos tea is an herbal tea made primarily from the South African red bush. Also, mate teas are an herbal tea made from the South American Yerba Mate plant. Finally, the more popular herbal tea category of herbal infusions can be made from a variety of ingredients including dried fruits, hibiscus, and rosehips.
