Tea

There are people who absolutely love drinking tea, and I'm one. There are so many kinds of teas to chose from and not all of them are my favourites, but a few are. I happen to love spicy chai. 
Herbal tea is one such type. Also called Tisanes, herbal tea is made from plants with no caffeine.

There are four actual teas in groups belonging to Green, White, Black and Oolong. All of those teas come from one evergreen plant called the Camellia Sinensis.

Some like to make fruit tea by brewing leaves from raspberries, strawberries, ect.

In ancient times, tea was only drunk as a form of medicine. It became a popular beverage drink in quite recent history.

A strange nickname for the process of making a cup of tea is "the agony of the leaves" when tea leaves unfold when hot water is poured.

Although I've said all of this, herbal tea isn't regarded as a normal tea because it doesn't come from the tea plant Camellia Sinensis. Herbal teas come from other sources like roots, fruit, flowers, rice, seeds and other leaves. In Tibet there is tea made from butter. In Italy there is tea from olive trees. The hibiscus flower produces a tea called karkade.

In the 17th and 18th centuries  European tea lovers found it so expensive that tea was locked away in caddies.
