| − | While [[tisanes]], also known as herbal teas, are made from various herbs, flowers, spices, or fruits, all tea, properly speaking, is made from the leaves of a single plant species. All true tea is produced from one of several varieties, naturally occurring or domesticated, of ''camellia sinensis''. Tea is generally classified in terms of how the leaves have been processed. White, green, black and oolong are the generally recognized Western designations, although there is considerable variety within these categories, especially the last one. Although it is little known in the West, pu-erh tea, made over years or even decades from moldy, decaying leaves, is also a popular variety in China. | + | While [[tisanes]], also known as herbal teas, are made from various herbs, flowers, spices, or fruits, all tea, properly speaking, is made from the leaves of a single plant species.
