<human>: I'm a little confused about the different types of tea and how they're made.
<bot>: There are many different types of teas, but all have one thing in common: They’re made from the leaves of the Camellia sinensis plant. The most popular type is black tea, which is typically made by steeping the leaves in hot water for several minutes. Green tea is also made from the same plant, but it's prepared differently—it's steeped in cold water instead of hot. Oolong tea is another variety that’s partially fermented before being dried. White tea is made from buds and young leaves, while herbal teas use a blend of herbs to flavor the brew.
