A confusing aspect of learning about tea is that many of the beverages which are called "tea" are actually not tea. Herbal teas, which tea experts term Tisanes (a French word for "herbal infusion"), are usually dried flowers, fruits or herbs steeped in boiling water (no actual tea leaves are included). Historically consumed for medicinal reasons or as a caffeine-free alternative, many tisanes (tih-ZANN) are beginning to find their own popularity outside the tea world. An interesting note: in Europe and some other countries, the use of the word "tea" is legally regulated to only apply to Camellia sinensis. Not so here in the United States...so don't feel bad if you've been confused!
We call them "teas" here to avoid any confusion but we may also reference them as tisanes or infusions.
