Tea originally referred to one species of shrub that was cultivated in China-Camellia sinensis-commonly called the black tea shrub. Over the years, the plant intermingled with herbs from many cultures, and tea took on a broader meaning to include an assortment of herbs. Tea now refers to a beverage made from the leaves, flowers, berries, seeds, roots, rhizomes, or bark of a plant, steeped in hot water.
