Insect tea refers to teas (in the broad sense, not always tea proper) made from leaves bitten by, and the droppings of, insects fed on specific plants. Most insect teas originate from the Southeast Asian region. They are often used in local traditional medicine, but have not been well-studied in the scientific literature.
Various insect teas are produced by small traditional communities particularly in the Southeast Asian hill regions, including southern China and Thailand. Not all insect sources and host plants have been studied or documented.
Some examples include:
Many chemicals in plants have evolved[ citation needed ] to protect them from insects. Insects in turn have evolved[ citation needed ] biochemical mechanisms or symbiotic relationships with microbes that allow them to consume these plants. The faecal matter often concentrates certain chemicals that produce distinctive flavours and tastes – and claimed effects on human health. Insect teas are widely used in traditional Asian medicine, particularly in China.
A few academic journals have published papers reporting pharmacological effects of some of these teas or of chemicals found in them, though little follow-up research has been done as of 2019. [update] For example, a 2015 Chinese study showed that polyphenols extracted from huaxiang tea reduced the count of liver cancer cells in vitro , by increasing their apoptosis rate (i.e., decreasing cell life-span). [8] The same paper also broadly claimed that "Traditional Chinese medicine can prevent and cure cancer", a view not widely accepted by science ).
Since the 2000s, drinks purporting to be sanye tea (with widely varying other ingredients) have been marketed, especially in the West, as a dietary supplement with unsubstantiated weight-loss, laxative, and detoxification claims.
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 southwestern 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 different 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.
Herbal teas, also known as herbal infusions and less commonly called tisanes, are beverages made from the infusion or decoction of herbs, spices, or other plant material in hot water; they do not usually contain any true tea. 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. Some herbal blends contain true tea.
Lapsang souchong or Zhengshan xiaozhong is a black tea consisting of Camellia sinensis leaves that may be smoke-dried over a pinewood fire. This smoking is accomplished either as a cold smoke of the raw leaves as they are processed or as a hot smoke of previously processed leaves. The intensity of the smoke aroma can be varied by locating the leaves closer or farther from the source of heat and smoke or by adjusting the duration of the process. The flavour and aroma of smoked lapsang souchong is described as containing empyreumatic notes, including wood smoke, pine resin, smoked paprika, and dried longan; it may be mixed with milk but is not bitter and usually not sweetened with sugar. The tea originates from the Wuyi Mountains region of Fujian and is considered a Wuyi tea. It is also produced in Taiwan. It has been labelled as smoked tea, smoky souchong, tarry lapsang souchong and lapsang souchong crocodile. While the tea leaf grading system adopted the term souchong to refer to a particular leaf position, lapsang souchong may be made with any leaf of the Camellia sinensis plant, though it is not unusual for the lower leaves, which are larger and less flavourful, to be used as the smoking compensates for the lower flavour profile and the higher leaves are more valuable for use in unflavoured or unblended teas. In addition to its consumption as a tea, lapsang souchong is also used in stock for soups, stews and sauces or otherwise as a spice or seasoning. Beginning in the early 21st century, an unsmoked variety of lapsang souchong was developed in the village of Tong Mu Guan in the Wuyi mountains. The unsmoked variety has become increasingly popular, particularly in the Chinese domestic market.
White tea may refer to one of several styles of tea which generally feature young or minimally processed leaves of the Camellia sinensis plant.
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.
Nilgiri tea is a drink made by infusing leaves of Camellia sinensis that is grown and processed in the Nilgiris district in Tamil Nadu, India. The leaves are processed as black tea, though some estates have expanded their product offerings to include leaves suitable for making green, white and oolong teas. It is generally described as being a brisk, fragrant and full-bodied tea. The region produces both rolled and crush, tear, curl tea and it is predominantly used for blending. Nilgiri tea is also used for making iced tea and instant tea.
Angelica sinensis, commonly known as dong quai or female ginseng, is a herb belonging to the family Apiaceae, indigenous to China. Angelica sinensis grows in cool high altitude mountains in East Asia. The yellowish brown root of the plant is harvested in the fall and is a well-known Chinese medicine which has been used for thousands of years.
Darjeeling tea is a tea made from Camellia sinensis var. sinensis that is grown and processed in Darjeeling district or Kalimpong district in West Bengal, India. Since 2004, the term Darjeeling tea has been a registered geographical indication referring to products produced on certain estates within Darjeeling and Kalimpong. The tea leaves are processed as black tea, though some estates have expanded their product offerings to include leaves suitable for making green, white, and oolong teas.
Tea seed oil is an edible plant oil. It is obtained from the seeds of Camellia oleifera.
Camellia oleifera, which originated in China, is notable as an important source of edible oil obtained from its seeds. It is commonly known as the oil-seed camellia or tea oil camellia, though to a lesser extent other species of camellia are used in oil production too.
Kuding is a particularly bitter-tasting Chinese infusion, which due to their similarities in appearance is derived from several plant species. The two most common plants used to make kuding are the wax tree species Ligustrum robustum and the holly species Ilex kaushue, the former being more commonly grown in Sichuan and Japan while the latter is most commonly grown and used in the rest of China. Tea produced from Ligustrum or many species of Ilex is caffeine-free, although not Ilex paraguariensis, the source of mate drank in South America.
Pseudopestalotiopsis theae is a plant pathogen affecting tea.
Pyralis farinalis, the meal moth, is a cosmopolitan moth of the family Pyralidae. Its larvae (caterpillars) are pests of certain stored foods, namely milled plant products.
Sang piao xiao or Sangpiaoxiao is a Pinyin transliteration referring to the oothecae, or egg case, of the praying mantis as an ingredient in traditional Chinese medicine. A formula based on this ingredient is known as sang piao xiao san and is also known as "mantis formula" in English. The formula may also be sold as a pill.
Taiwanese tea includes four main types: oolong tea, black tea, green tea and white tea. The earliest record of tea trees found in Taiwan is from 1717 in Shui Sha Lian (水沙連), present-day Yuchi and Puli, Nantou County. Some of the teas retain the island country's former name, Formosa.
Homona coffearia, the tea tortrix or camellia tortrix, is a moth of the family Tortricidae. The species was first described by Nietner in 1861. It is widely distributed in the Oriental region.
Jacobiasca formosana, the tea jassid, is an insect species belonging to the subfamily Typhlocybinae of the family Cicadellidae. Plant hosts include Gossypium (cotton) species and, notably, Camellia sinensis. The species is distributed throughout East, Southeast, and South Asia.
Psychoactive plants are plants, or preparations thereof, that upon ingestion induce psychotropic effects. As stated in a reference work:
Psychoactive plants are plants that people ingest in the form of simple or complex preparations in order to affect the mind or alter the state of consciousness.
Camellia taliensis is a small species of evergreen shrub whose leaves and leaf buds are used to produce tea.
Camellia ptilophylla, also called the cocoa tea plant, is a species of Camellia plant found in Southern Asia. It has insignificant levels of naturally occurring caffeine, unlike other varieties of the plant used to make tea.
