Human: I'm a little confused about the different types of tea and how they're made. Assistant: 
There are many different types of teas, including black tea, green tea, oolong tea, white tea, herbal teas, rooibos, and matcha. Black tea is typically made from leaves that have been fermented for longer than other teas. Green tea is made from young, unfermented leaves. Oolong tea is partially oxidized, while white tea is fully oxidized. Herbal teas use a variety of plants to make them, such as chamomile, lavender, and mint. Rooibos is an herbal tea from South Africa that has been traditionally used to treat various ailments. Matcha is powdered green tea that's mixed with hot water and whisked together to create a frothy drink.
