Labrador Tea
Labrador tea is a common name for three closely related plant species in the genus ''Rhododendron'' as well as a herbal tea made from their leaves. All three species are primarily wetland plants in the Ericaceae, heath family. Labrador tea has been a favorite beverage for a long time among the Dene and Inuit peoples. Description All three species used to make Labrador tea are low, slow-growing shrubs with evergreen leaves: * ''Rhododendron tomentosum'' (northern Labrador tea, previously ''Ledum palustre''), * ''Rhododendron groenlandicum'', (bog Labrador tea, previously ''Ledum groenlandicum'' or ''Ledum latifolium'') and * ''Rhododendron neoglandulosum'', (western Labrador tea, or trapper's tea, previously ''Ledum glandulosum'' or ''Ledum columbianum''). The leaves are smooth on top with often wrinkled edges, and fuzzy white to red-brown underneath, and point straight to the sides or downward. ''R. tomentosum'', ''R. groenlandicum'', and ''R. neoglandulosum'' can be found in w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhododendron Tomentosum
''Rhododendron tomentosum'' ( syn. ''Ledum palustre''), commonly known as marsh Labrador tea, northern Labrador tea, marsh rosemary or wild rosemary, is a flowering plant in the subsection '' Ledum'' of the large genus ''Rhododendron'' in the family Ericaceae. Description It is a low shrub growing to 50 cm (rarely up to 120 cm) tall with evergreen leaves 12–50 mm long and 2–12 mm broad. The flowers are small, with a five-lobed white corolla, and produced several together in a corymb 3–5 cm diameter. They emit strong smell to attract bees and other pollinating insects.

Labrador () is a geographic and cultural region within the Canadian province of Newfoundland and Labrador. It is the primarily continental portion of the province and constitutes 71% of the province's area but is home to only 6% of its population. It is separated from the island of Newfoundland by the Strait of Belle Isle. It is the largest and northernmost geographical region in the four Atlantic provinces. Labrador occupies most of the eastern part of the Labrador Peninsula. It is bordered to the west and south by the province of Quebec. Labrador also shares a small land border with the territory of Nunavut on Killiniq Island. The indigenous peoples of Labrador include the Northern Inuit of Nunatsiavut, the Southern Métis of NunatuKavut, and the Innu of Nitassinan. Etymology Labrador is named after João Fernandes Lavrador, a Portuguese explorer who sailed along the coasts of the Labrador Peninsula in 1498–99.Kevin Major, '' As Near to Heaven by Sea: A History of Newfoundl ...

Plant Common Names
Plants are the eukaryotes that form the kingdom Plantae; they are predominantly photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants ( hornworts, liverworts, mosses, lycophytes, ferns, conifers and other gymnosp ...

Inuit Cuisine
Historically, Inuit cuisine, which is taken here to include Greenlandic, Yupʼik and Aleut cuisine, consisted of a diet of animal source foods that were fished, hunted, and gathered locally. In the 20th century the Inuit diet began to change and by the 21st century the diet was closer to a Western diet. After hunting, they often honour the animals' spirit by singing songs and performing rituals. Although traditional or country foods still play an important role in the identity of Inuit, much food is purchased from the store, which has led to health problems and food insecurity. According to Edmund Searles in his article ''Food and the Making of Modern Inuit Identities'', they consume this type of diet because a mostly meat diet is "effective in keeping the body warm, making the body strong, keeping the body fit, and even making that body healthy". Food sources * Hunted meats: ** Sea mammals such as walrus, seal, and whale. Whale meat generally comes from the narwhal, beluga ...

Herbal Teas
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 Traditional medicine, 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 tea, black, green tea, green, white tea, white, yellow tea, 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, ...

They refer to ... doll that served both as a children's toy and as a cache of tea. Known as Innikueu in Innu, the dolls were stuffed with tea that could be recovered and used by hunters in times of need. The dolls were carried by the children of hunters, to save weight on the hunt. Once the tea had been consumed, the doll was re-stuffed with grass or leaves. References {{reflist Traditional dolls Innu culture ...

Grayanotoxins
Grayanotoxins are a group of closely related neurotoxins named after ''Leucothoe grayana'', a plant native to Japan and named for 19th-century American botanist Asa Gray. Grayanotoxin I (grayanotoxane-3,5,6,10,14,16-hexol 14-acetate) is also known as andromedotoxin, acetylandromedol, rhodotoxin and asebotoxin. Grayanotoxins are produced by ''Rhododendron'' species and other plants in the family Ericaceae. Honey made from the nectar and so containing pollen of these plants also contains grayanotoxins and is commonly referred to as mad honey. Consumption of the plant or any of its secondary products, including mad honey, can cause a rare poisonous reaction called grayanotoxin poisoning, mad honey disease, honey intoxication, or rhododendron poisoning. It is most frequently produced and consumed in regions of Turkey and Nepal as a recreational drug and traditional medicine. Origin Grayanotoxins are produced by plants in the family Ericaceae, specifically members of the genera ''A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ledol
Ledol is a poisonous sesquiterpene that can cause cramps, paralysis, and delirium. Peoples of the Caucasus, Caucasian peasants used ''Rhododendron'' plants for these effects in shamanism, shamanistic rituals. Ledol resides in the essential oils of certain plants and when crushed, these oils are released. One of the plants with the highest concentration of these essential oils is Rhododendron tomentosum. The word "ledol" comes from the Greek language, Greek word "ledos" meaning "robe". This likely comes from the "wooly" appearance of the plant, which has hair-like stalks stemming from the flower. Historical and Traditional Uses The earliest known written record of Rhododendron plant toxicity dates back to 401 B.C. in China. Despite their toxicity, Rhododendron species have been documented in traditional medicinal practices across various cultures, including Chinese, Ayurvedic, European, and North American practices. The accounts of Rhododendron from around the world describe nume ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terpenoid
The terpenoids, also known as isoprenoids, are a class of naturally occurring organic compound, organic chemicals derived from the 5-carbon compound isoprene and its derivatives called terpenes, diterpenes, etc. While sometimes used interchangeably with "terpenes", terpenoids contain additional functional groups, usually containing oxygen. When combined with the hydrocarbon terpenes, terpenoids comprise about 80,000 compounds. They are the largest class of plant secondary metabolites, representing about 60% of known Natural Products, natural products. Many terpenoids have substantial pharmacological bioactivity and are therefore of interest to medicinal chemists. Plant terpenoids are used for their aromatic qualities and play a role in traditional herbal remedies. Terpenoids contribute to the scent of eucalyptus, the flavors of cinnamon, cloves, and ginger, the yellow color in sunflowers, and the red color in tomatoes. Well-known terpenoids include citral, menthol, camphor, salvin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diuresis
Diuresis () is the excretion of urine, especially when excessive (polyuria). The term collectively denotes the physiologic processes underpinning increased urine production by the kidneys during maintenance of fluid balance. In healthy people, the drinking of extra water produces mild diuresis to maintain the body water balance. Many people with health issues, such as heart failure and kidney failure, need diuretic medications to help their kidneys deal with the fluid overload of edema. These drugs promote water loss via urine production. The concentrations of electrolytes in the blood are closely linked to fluid balance, so any action or problem involving fluid intake or output (such as polydipsia, polyuria, diarrhea, heat exhaustion, starting or changing doses of diuretics, and others) can require management of electrolytes, whether through self-care in mild cases or with help from health professionals in moderate or severe cases. Osmotic diuresis Osmotic diuresis is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
