Petasites Japonicus
''Petasites japonicus'', also known as butterbur, giant butterbur, great butterbur and sweet-coltsfoot, is an herbaceous perennial plant in the family Asteraceae. It is native to China, Japan, Korea and Sakhalin and introduced in Europe and North America. It was introduced to southern British Columbia in Canada by Japanese migrants. It is dioecious, with male and female flowers produced on separate individuals. Occasionally, morphologically hermaphroditic (but functionally sterile) flowers exist. Uses The traditional preparation method for this vegetable involves pre-treating with ash or baking soda and soaking in water to remove harshness (astringency), which is a technique known as . The shoot can be chopped and stir fried with miso to make ''fuki-miso'' which is eaten as a relish thinly spread over hot rice at meals. The bulb-like shoots are also picked fresh and fried as tempura. In Korea, it is steamed or boiled and then pressed to remove water. Sesame oil or perilla oi ...

Philipp Franz Von Siebold
Philipp Franz Balthasar von Siebold (17 February 1796 – 18 October 1866) was a German physician, botanist and traveler. He achieved prominence by his studies of Japanese flora (plants), flora and fauna (animals), fauna and the introduction of Western medicine in Japan. He was the father of the first female Japanese doctor educated in Western medicine, Kusumoto Ine. Career Early life Born into a family of doctors and professors of medicine in Würzburg (then in the Bishopric of Würzburg, later part of Bavaria), Siebold initially studied medicine at the University of Würzburg from November 1815, where he became a member of the German Student Corps, Corps Moenania Würzburg. One of his professors was Franz Xaver Heller (1775–1840), author of the ' ("Flora of the Grand Duchy of Würzburg", 1810–1811). Ignaz Döllinger (1770–1841), his professor of anatomy and physiology, however, most influenced him. Döllinger was one of the first professors to understand and tr ...

Pyrrolizidine Alkaloid
Pyrrolizidine alkaloids (PAs), sometimes referred to as necine bases, are a group of naturally occurring alkaloids based on the structure of pyrrolizidine. Pyrrolizidine alkaloids are produced by plants as a defense mechanism against insect herbivores. More than 660 PAs and PA N-oxides have been identified in over 6,000 plants, and about half of them exhibit hepatotoxicity. They are found frequently in plants in the Boraginaceae, Asteraceae, Orchidaceae and Fabaceae families; less frequently in the Convolvulaceae and Poaceae, and in at least one species in the Lamiaceae. It has been estimated that 3% of the world’s flowering plants contain pyrrolizidine alkaloids. Honey can contain pyrrolizidine alkaloids, as can grains, milk, offal and eggs. To date (2011), there is no international regulation of PAs in food, unlike those for herbs and medicines. Unsaturated pyrrolizidine alkaloids are hepatotoxic, that is, damaging to the liver. PAs also cause hepatic veno-occlusive disea ...

Flora Of Japan
The flora of Japan comprises a large assemblage of plant species which can be found in Japan, such as sakura, katsura, momiji and azalea. There are many species which are endemic to Japan. Diversity Japan has significant diversity in flora. Of approximately 5,600 total vascular plant species, almost 40% are endemic. This richness is due to the significant variation in latitude and altitude across the country, a diversity of climatic conditions due to monsoons, and multiple geohistorical incidences of connections with the mainland. Vegetation types Japan consists of roughly 4 vegetation zones that are delineated by temperature and precipitation: the alpine region, subalpine region, summer-green broad-leaved forest region and evergreen broad-leaved forest region. Due to its substantial length of over 3,000 km from north to south and its mountain ranges that can exceed 3,000 meters, Japan's vegetation varies by latitude and by altitude. Evergreen forests tend to appear in ...

YOKOHAMA
is the second-largest city in Japan by population and the most populous municipality of Japan. It is the capital city and the most populous city in Kanagawa Prefecture, with a 2020 population of 3.8 million. It lies on Tokyo Bay, south of Tokyo, in the Kantō region of the main island of Honshu. Yokohama is also the major economic, cultural, and commercial hub of the Greater Tokyo Area along the Keihin region, Keihin Industrial Zone. Yokohama was one of the cities to open for trade with the Western world, West following the 1859 end of the Sakoku, policy of seclusion and has since been known as a cosmopolitan port city, after Kobe opened in 1853. Yokohama is the home of many Japan's firsts in the Meiji (era), Meiji period, including the first foreign trading port and Chinatown (1859), European-style sport venues (1860s), English-language newspaper (1861), confectionery and beer manufacturing (1865), daily newspaper (1870), gas-powered street lamps (1870s), railway station (1 ...

Korpokkur
Korpokkur ( ain, コㇿポックㇽ; ja, コロポックル, translit=Koropokkuru), also written Koro-pok-kuru, korobokkuru, korbokkur, or koropokkur,Ainu-Grammatik, vol.2 Hans Adalbert Dettmer, O. Harrassowitz, 1997 koro-pok-guru, are a race of small people in folklore of the Ainu people of the northern Japanese islands. The name is traditionally analysed as a tripartite compound of ''kor'' (" butterbur plant"), ''pok'' ("under, below"), and ''kur'' ("person") and interpreted to mean "people below the leaves of the Fuki" in the Ainu language. The Ainu believe that the ''korpokkur'' were the people who lived in the Ainu's land before the Ainu themselves lived there. They were short of stature, agile, and skilled at fishing. They lived in pits with roofs made from butterbur leaves. Long ago, the ''korpokkur'' were on good terms with the Ainu, and would send them deer, fish, and other game and exchange goods with them. The little people hated to be seen, however, so they would st ...

Ainu People
The Ainu are the indigenous people of the lands surrounding the Sea of Okhotsk, including Hokkaido Island, Northeast Honshu Island, Sakhalin Island, the Kuril Islands, the Kamchatka Peninsula and Khabarovsk Krai, before the arrival of the Yamato Japanese and Russians. These regions are referred to as in historical Japanese texts. Official estimates place the total Ainu population of Japan at 25,000. Unofficial estimates place the total population at 200,000 or higher, as the near-total assimilation of the Ainu into Japanese society has resulted in many individuals of Ainu descent having no knowledge of their ancestry. As of 2000, the number of "pure" Ainu was estimated at about 300 people. In 1966, there were about 300 native Ainu speakers; in 2008, however, there were about 100. Names This people's most widely known ethnonym, "Ainu" ( ain, ; ja, アイヌ; russian: Айны) means "human" in the Ainu language, particularly as opposed to , divine beings. Ainu also i ...

Blood Plasma
Blood plasma is a light amber-colored liquid component of blood in which blood cells are absent, but contains proteins and other constituents of whole blood in suspension. It makes up about 55% of the body's total blood volume. It is the intravascular part of extracellular fluid (all body fluid outside cells). It is mostly water (up to 95% by volume), and contains important dissolved proteins (6–8%; e.g., serum albumins, globulins, and fibrinogen), glucose, clotting factors, electrolytes (, , , , , etc.), hormones, carbon dioxide (plasma being the main medium for excretory product transportation), and oxygen. It plays a vital role in an intravascular osmotic effect that keeps electrolyte concentration balanced and protects the body from infection and other blood-related disorders. Blood plasma is separated from the blood by spinning a vessel of fresh blood containing an anticoagulant in a centrifuge until the blood cells fall to the bottom of the tube. The blood plasma is t ...

Hepatotoxic
Hepatotoxicity (from ''hepatic toxicity'') implies chemical-driven liver damage. Drug-induced liver injury is a cause of acute and chronic liver disease caused specifically by medications and the most common reason for a drug to be withdrawn from the market after approval. The liver plays a central role in transforming and clearing chemicals and is susceptible to the toxicity from these agents. Certain medicinal agents, when taken in overdoses (e.g. paracetamol) and sometimes even when introduced within therapeutic ranges (e.g. halothane), may injure the organ. Other chemical agents, such as those used in laboratories and industries, natural chemicals (e.g., microcystins), and herbal remedies (two prominent examples being kava, mechanism unknown, and comfrey, through its pyrrolizidine alkaloid content) can also induce hepatotoxicity. Chemicals that cause liver injury are called hepatotoxins. More than 900 drugs have been implicated in causing liver injury (see LiverTox, exter ...

Carcinogenic
A carcinogen is any substance, radionuclide, or radiation that promotes carcinogenesis (the formation of cancer). This may be due to the ability to damage the genome or to the disruption of cellular metabolic processes. Several radioactive substances are considered carcinogens, but their carcinogenic activity is attributed to the radiation, for example gamma rays and alpha particles, which they emit. Common examples of non-radioactive carcinogens are inhaled asbestos, certain dioxins, and tobacco smoke. Although the public generally associates carcinogenicity with synthetic chemicals, it is equally likely to arise from both natural and synthetic substances. Carcinogens are not necessarily immediately toxic; thus, their effect can be insidious. Carcinogens, as mentioned, are agents in the environment capable of contributing to cancer growth. Carcinogens can be categorized into two different types: activation-dependent and activation-independent, and each nature impacts their level ...
