White tea, herbal tea and instant tea are other popular variants amongst a plethora of others. White teas are produced from only the tips (also known as tea buds) of the tea plant. Herbal teas often aren’t “teas” at all. Most don’t contain camellia sinensis, and are processed plant material such as camomile flowers or peppermint leaves. Instant tea is granulated tea that mixes with either hot or cold water.
