Herbal teas are often categorized with commercial teas, such as green or black tea. They are packaged like tea, infused like tea, and enjoyed like tea, but they actually aren't teas at all since they do not come from the camellia sinensis bush that tea is derived from. Herbal teas are actually herbal infusions and tisanes that derives from the herbs, leaves, berries and seeds, from the entire plant or tree. The quality of herbal tea is directly related to the specialized nature in which herbs are harvested. The plant's natural juices and oils are at their best and most concentrated as their flowers begin to bud. Segments of the plant that are picked depending on the type of plant and the usage intended for leaves, flowers, roots, bark and seeds are all potential tea ingredients. The process of growing and producing herbal blends should adhere natural conditions from start to finish, which accounts for a major composition of the tea is inherent richness and flavour. The quality of herbal tisanes can differ between origins. Peppermint is mainly produced in Europe, but also in Northern Africa and Eastern Europe. Peppermint grown in Germany tends to be fresher than those grown in Eastern Europe. The Hibiscus herb is mainly produced in Thailand, Sudan and China. It is crucial to understand the point of origin to assure the proper quality and flavour of the herbs. Lemongrass, chamomile, rosehip, hibiscus are most popular among regular herbal blends. In loose-leaf teas, visual impact is very important and often the look of the herb reveals what to expect in the flavour.
