Infusion
Infusion is the process of extracting chemical compounds or flavors from plant material in a solvent such as water, oil or alcohol, by allowing the material to remain suspended in the solvent over time (a process often called steeping). An infusion is also the name for the resultant liquid. The process of infusion is distinct from both decoction—a method of extraction involving boiling the plant material—and percolation, in which water is passed through the material (as in a coffeemaker). History The first recorded use of essential oils was in the 10th or 11th century by the Persian polymath Avicenna, possibly in ''The Canon of Medicine''. Tea is far older than this, dating back to the 10th century BC as the earliest recorded reference. Preparation techniques Infusion is a chemical process that uses botanicals (typically dried herbs, flowers or berries) that are volatile and release their active ingredients readily in water, oil, or alcohol. In this process, a liquid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |

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 ...

Decoction
Decoction is a method of extraction by boiling herbal or plant material (which may include stems, roots, bark and rhizomes) to dissolve the chemicals of the material. It is the most common preparation method in various herbal medicine systems. Decoction involves first drying the plant material; then mashing, slicing, or cutting the material to allow for maximum dissolution; and finally boiling in water to extract oils, volatile organic compounds and other various chemical substances. Occasionally, aqueous ethanol or glycerol may be used instead of water. Decoction can be used to make tisanes, tinctures and similar solutions. Decoctions and infusions may produce liquids with differing chemical properties, as the temperature or preparation difference may result in more oil-soluble chemicals in decoctions versus infusions. The process can also be applied to meats and vegetables to prepare bouillon or stock, though the term is typically only used to describe boiled plant extracts, usu ...

Mate (drink)
Mate ( ; Spanish: , Portuguese: ) is a traditional South American caffeine-rich infused herbal drink. It is also known as in Portuguese, in Spanish, and ''kaʼay'' in Guarani. It is made by soaking dried yerba mate (''Ilex paraguariensis'') leaves in hot water and is traditionally served with a metal straw () in a container typically made from a calabash gourd (also called the ), from water-resistant hardwoods such as Lapacho or Palo Santo, and also made from a cattle horn () in some areas. A very similar preparation, known as , removes some of the plant material and sometimes comes in tea bags. Today, mate is sold commercially in tea bags and as bottled iced tea. Mate has been originally consumed by the Guaraní and Tupi peoples native to Paraguay, north-east of Argentina and South of Brazil. After European colonization, it was spread across the Southern Cone countries, namely Argentina, Paraguay, Uruguay and Chile, but it is also consumed in the South of Brazil and ...

Coffee
Coffee is a beverage brewed from roasted, ground coffee beans. Darkly colored, bitter, and slightly acidic, coffee has a stimulating effect on humans, primarily due to its caffeine content, but decaffeinated coffee is also commercially available. There are also various coffee substitutes. Typically served hot, coffee has the highest sales in the world market for hot drinks. Coffee production begins when the seeds from coffee cherries (the '' Coffea'' plant's fruits) are separated to produce unroasted green coffee beans. The "beans" are roasted and then ground into fine particles. Coffee is brewed from the ground roasted beans, which are typically steeped in hot water before being filtered out. It is usually served hot, although chilled or iced coffee is common. Coffee can be prepared and presented in a variety of ways (e.g., espresso, French press, caffè latte, or already-brewed canned coffee). Sugar, sugar substitutes, milk, and cream are often added to mask ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chamomile
Chamomile (American English) or camomile (British English; see spelling differences) ( or ) is the common name for several plants of the family Asteraceae. Two of the species, '' Matricaria chamomilla'' and '' Chamaemelum nobile'', are commonly used to make herbal infusions for beverages. Chamomile is used as a flavoring in foods, beverages, and cosmetics, in herbal teas, in brewing beer, and as a ground cover or seating plant in gardens. There is no clinical evidence supporting the effectiveness of consuming chamomile to treat any diseases. Chamomile may interact adversely with various herbs and drugs, worsen pollen allergies, and is not recommended for people with hormone-sensitive conditions or when combined with anticoagulants. Because Roman chamomile may cause uterine contractions, it should not be used during pregnancy, and its safety during breastfeeding is unknown. Chamomile is highly susceptible to numerous fungi, Virus, viruses, and Insect, insects, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sloe Gin
Sloe gin is a British red liqueur made with gin and Prunus spinosa, blackthorn fruits (sloes), which are the drupe fruit of the ''Prunus spinosa'' tree, which is a relative of the plum. As an alcoholic drink, sloe gin contains between 15 per cent and 30 per cent alcohol by volume (ABV); however, European Union regulations established 25 per cent ABV as the minimal alcoholic content for the blackthorn beverage to be a ''sloe gin''. Historically, despite being a liqueur based upon gin, the EU included the colloquial name ''sloe gin'' to the legal definitions; thus, sloe gin is the only alcoholic beverage that legally uses the term ''gin'' without appending the ''liqueur'' suffix. The traditional method of preparation of sloe gin is to soak the blackthorns (sloes) in gin with some sugar, and the mixture sweetens when the blackthorn fruit mature in the alcohol. Commercial sloe gin is made by flavouring an inexpensive neutral grain spirit. US distilleries use close fruits related to ...

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 ...

Botanicals
Herbal medicine (also called herbalism, phytomedicine or phytotherapy) is the study of pharmacognosy and the use of medicinal plants, which are a basis of traditional medicine. Scientific evidence for the effectiveness of many herbal treatments remains limited, prompting ongoing regulatory evaluation and research into their safety and efficacy. Standards for purity or dosage are generally not provided. The scope of herbal medicine sometimes includes fungal and bee products, as well as minerals, shells and certain animal parts. Paraherbalism is the pseudoscientific use of plant or animal extracts as medicine, relying on unproven beliefs about the safety and effectiveness of minimally processed natural substances. Herbal medicine has been used since at least the Paleolithic era, with written records from ancient Sumer, Egypt, Greece, China, and India documenting its development and application over millennia. Modern herbal medicine is widely used globally—especially in Asia a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chinese Tea
Chinese teas can be classified into six distinctive categories: White tea, white, Green tea, green, Yellow tea, yellow, Oolong tea, oolong, Black tea, black and Post-fermented tea, post-fermented. Others add categories for scented and compressed teas. All of these come from varieties of the ''Camellia sinensis'' plant. Most Chinese teas are cultivated and consumed in China. It is commonly available in Chinese restaurants and grocery shops worldwide. Green tea is the most common type of tea consumed in China, while black tea is the second most common. Within these main categories of tea are vast varieties of individual beverages. Some of the variations are due to different strains of the ''Camellia'' plant. However, the largest factor in the wide variations comes from differences in tea processing after the tea leaves are harvested. White and green teas are heat-treated () soon after picking to prevent redox, oxidation. Other differences come from variations in the processing steps. ...
