Tea
Tea is an aromatic beverage prepared by pouring hot or boiling water over cured or fresh leaves of '' Camellia sinensis'', an evergreen shrub native to East Asia which probably originated in the borderlands of south-western China and northern Myanmar. Tea is also made, but rarely, from the leaves of '' Camellia taliensis''. After plain water, tea is the most widely consumed drink in the world. There are many types of tea; some have a cooling, slightly bitter, and astringent flavour, while others have profiles that include sweet, nutty, floral, or grassy notes. Tea has a stimulating effect in humans, primarily due to its caffeine content. An early credible record of tea drinking dates to the third century AD, in a medical text written by Chinese physician Hua Tuo. It was popularised as a recreational drink during the Chinese Tang dynasty, and tea drinking spread to other East Asian countries. Portuguese priests and merchants introduced it to Europe during the 16th cen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Green Tea
Green tea is a type of tea made from the leaves and buds of the '' Camellia sinensis'' that have not undergone the withering and oxidation process that creates oolong teas and black teas. Green tea originated in China in the late 1st millennium BC, and since then its production and manufacture has spread to other countries in East Asia. Several varieties of green tea exist, which differ substantially based on the variety of ''C. sinensis'' used, growing conditions, horticultural methods, production processing, and time of harvest. While it may slightly lower blood pressure and improve alertness, current scientific evidence does not support most health benefit claims, and excessive intake of green tea extracts can cause liver damage and other side effects. History Tea consumption has its legendary origins in China during the reign of mythological Emperor Shennong. A book written by Lu Yu in 618–907 AD, '' The Classic of Tea'' ( zh, t= 茶 經, s=, p=chájīng), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Longjing Tea
Longjing tea (; Standard Mandarin pronunciation ), sometimes called by its literal translated name Dragon Well tea, is a variety of pan-roasted green tea from the area of Longjing, Hangzhou, Longjing Village in Hangzhou, Zhejiang Province, China. It is produced mostly by hand and renowned for its high quality, earning it the List of Chinese teas#Ten Famous Teas, China Famous Tea title. Nutritional information Longjing tea contains vitamin C, amino acids, and, like most finer Chinese green teas, has high concentrations of tea catechins, catechins. Environmental requirements for growth Water The overall water content of tea plants is 55%–60%, but the water content of new shoots is as high as 70%–80%. In the tea picking process, the continuous regrowth of new shoots therefore needs a constant supply of water. Therefore, Longjing tea trees need more water than ordinary trees. It is suggested that the growth and development of tea trees were most suitable when the annual pre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camellia Sinensis
''Camellia sinensis'' is a species of evergreen shrub or small tree in the flowering plant family Theaceae. Its leaves, leaf buds, and stems can be used to produce tea. Common names include tea plant, tea shrub, and tea tree (unrelated to ''Melaleuca alternifolia'', the source of tea tree oil, or the genus ''Leptospermum'' commonly called tea tree). White tea, yellow tea, green tea, oolong, dark tea (which includes pu-erh tea) and black tea are all harvested from two of the five varieties which form the main crops now grown, ''C. sinensis'' var. ''sinensis'' and ''C. s.'' var. ''assamica'', but are Tea processing, processed differently to attain varying levels of oxidation with black tea being the most oxidized and white being the least. Kukicha (twig tea) is also harvested from ''C. sinensis'', but uses twigs and stems rather than leaves. Description ''Camellia sinensis'' is native to East Asia, the Indian Subcontinent, and Southeast Asia, but it is today cultivated all aro ...

Drink
A drink or beverage is a liquid intended for human consumption. In addition to their basic function of satisfying thirst, drinks play important roles in human culture. Common types of drinks include plain drinking water, milk, juice, smoothies and soft drinks. Traditionally Hot beverage, warm beverages include coffee, tea, and hot chocolate. Caffeinated drinks that contain the stimulant caffeine have a long history. In addition, alcoholic drinks such as wine, beer, and liquor, which contain the drug ethanol, have been part of human culture for more than 8,000 years. Non-alcoholic drinks often signify drinks that would normally contain alcohol, such as beer, wine and cocktails, but are made with a sufficiently low concentration of alcohol by volume. The category includes drinks that have undergone an alcohol removal process such as Low-alcohol beer, non-alcoholic beers and de-alcoholized wines. Biology When the human body becomes dehydrated, a person experiences thirst. This c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caffeine
Caffeine is a central nervous system (CNS) stimulant of the methylxanthine chemical classification, class and is the most commonly consumed Psychoactive drug, psychoactive substance globally. It is mainly used for its eugeroic (wakefulness promoting), ergogenic (physical performance-enhancing), or nootropic (cognitive-enhancing) properties. Caffeine acts by blocking the binding of adenosine at a number of adenosine receptor types, inhibiting the centrally depressant effects of adenosine and enhancing the release of acetylcholine. Caffeine has a three-dimensional structure similar to that of adenosine, which allows it to bind and block its receptors. Caffeine also increases Cyclic adenosine monophosphate, cyclic AMP levels through nonselective Phosphodiesterase inhibitor, inhibition of phosphodiesterase, increases calcium release from intracellular stores, and Receptor antagonist, antagonizes GABA receptor, GABA receptors, although these mechanisms typically occur at concentrati ...

Herbal Tea
Herbal teas, technically known as herbal infusions, and less commonly called tisanes (UK and US , US also ), are beverages made from the infusion or decoction of herbs, spices, or other plant material in hot water. Often herb tea, or the plain term ''tea'', is used as a reference to all sorts of herbal teas. Many herbs used in teas/tisanes are also used in herbal medicine and in folk medicine. These "teas" do not usually contain any true '' tea'' ('' Camellia sinensis''), but some herbal blends do contain true tea (e.g., the Indian classic masala chai). The term "herbal" tea is often used to distinguish these beverages from "true" teas (e.g., black, green, white, yellow, oolong), which are prepared from the cured leaves of the tea plant, '' Camellia sinensis''. Unlike true teas, most tisanes do not naturally contain caffeine (though tea can be decaffeinated, i.e., processed to remove caffeine). A number of plants, however, ''do'' contain psychoactive compounds, such a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gaiwan
A (; ) or () is a Chinese lidded bowl without a handle, used for the infusion of tea leaves and the consumption of tea. It was invented during the Ming dynasty. It consists of a bowl, a lid, and a saucer. History Prior to the Ming dynasty (1368–1644), tea was normally consumed from the vessel in which it was prepared. As described by the tea master Lu Yu, this special bowl had to be large enough to accommodate the implements and actions of tea brewing, though compact enough to be held comfortably in the hands for consumption. The term for this versatile piece of equipment was (; lit. 'tea bowl'). It was during the Ming dynasty that the innovations in both tea ritual and tea preparation gave rise to the gaiwan.

Steeping
Steeping is the soaking of an organic solid, such as leaves, in a liquid (usually water) to extract flavours or to soften it. The specific process of teas being prepared for drinking by leaving the leaves in heated water to release the flavour and nutrients is known as steeping. Herbal teas may be prepared by decoction, infusion, or maceration. Some solids are soaked to remove an ingredient, such as salt, where the solute is not the desired product. Corn One example is the steeping of corn (or maize), part of the milling process. As described by the US Corn Refiners Association, harvested kernels of corn are cleaned and then steeped in water at a temperature of for 30 to 40 hours. In the process their moisture content rises from 15% to 45% and their volume more than doubles. The gluten bonds in the corn are weakened and starch is released. The corn is then ground to break free the germ and other components, and the water used (steepwater), which has absorbed various n ...

Tang Dynasty
The Tang dynasty (, ; zh, c=唐朝), or the Tang Empire, was an Dynasties of China, imperial dynasty of China that ruled from 618 to 907, with an Wu Zhou, interregnum between 690 and 705. It was preceded by the Sui dynasty and followed by the Five Dynasties and Ten Kingdoms period. Historians generally regard the Tang as a high point in Chinese civilisation, and a Golden age (metaphor), golden age of cosmopolitan culture. Tang territory, acquired through the military campaigns of its early rulers, rivalled that of the Han dynasty. The House of Li, Li family founded the dynasty after taking advantage of a period of Sui decline and precipitating their final collapse, in turn inaugurating a period of progress and stability in the first half of the dynasty's rule. The dynasty was formally interrupted during 690–705 when Empress Wu Zetian seized the throne, proclaiming the Wu Zhou dynasty and becoming the only legitimate Chinese empress regnant.

Rooibos
Rooibos ( ; , ), or , is a broom (shrub), broom-like member of the plant family Fabaceae that grows in South Africa's Fynbos biome. The leaves are used to make a caffeine-free herbal tea, herbal infusion that has been popular in Southern Africa for generations. Since the 2000s, rooibos has gained popularity internationally, with an earthy flavour and aroma that is similar to yerba mate or tobacco. Outside of Southern Africa, it is called bush tea, red tea, or redbush tea (predominantly in Great Britain). The name ''rooibos'' is Afrikaans deriving from , meaning . The name is protected in South Africa and has protected designation of origin status in the EU. Rooibos was formerly classified in the genus but is now thought to be part of , following Rolf Dahlgren, Dahlgren (1980). The specific name (botany), specific name of , for the plant's linear growing structure and needle-like leaves, was given by Nicolaas Laurens Burman, Burman (1759). Production and processing Roo ...

Shrub
A shrub or bush is a small to medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple Plant stem, stems and shorter height, less than tall. Small shrubs, less than tall are sometimes termed as subshrubs. Many botany, botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead. Some define a shrub as less than and a tree as over 6 m. Others use as the cutoff point for classification. Many trees do not reach this mature height because of hostile, less than ideal growing conditions, and resemble shrub-sized plants. Others in such species have the potential to grow taller in ideal conditions. For longevity, most shrubs are classified between Perennial plant, perennials and trees. Some only last about five years in good conditions. Others, usually larger and more woody, live beyond ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
