Petasites japonicus, also known as butterbur, giant butterbur, great butterbur and sweet-coltsfoot, is an herbaceous perennial plant in the family Asteraceae. [3] 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. [4] [5]
It is dioecious, with male and female flowers produced on separate individuals. Occasionally, morphologically hermaphroditic (but functionally sterile) flowers exist. [6]
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 aku-nuki (灰汁抜き, literally "harshness removal"). 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 oil is added in order to make namul.
Like other Petasites species, fuki contains pyrrolizidine alkaloids (PAs) which have been associated with cumulative damage to the liver and tumor formation. [7] [8] It also contains the carcinogenic PA petasitenine. [8] The concentration of hepatotoxic PAs can be reduced to a concentration below detection limits with a proper extraction process. [9] Since many alkaloids are bitter, traditional methods of preparation may have evolved to remove them.
Certain extracts of Petasites japonicus have found to be anti-inflammatory in a study of asthma in mice. [10] Based on additional studies in mice, the plant may contain blood plasma and hepatic lipid-lowering and antioxidant compounds. [11]
The Ainu people refer to the previous inhabitants of Ezo as the Korpokkur or "people who dwelt below ground"; the name can also be interpreted as "people beneath the fuki", and so they are popularly associated with fuki leaves in art and mythology. More fantastic depictions of the Korpokkur portray them as tiny, fairy-like creatures small enough to use the leaves as roofs or umbrellas. [12]
Miso is a traditional Japanese seasoning. It is a thick paste produced by fermenting soybeans with salt and kōji, and sometimes rice, barley, seaweed, or other ingredients. It is used for sauces and spreads; pickling vegetables, fish, or meats; and mixing with dashi soup stock to serve as miso soup, a Japanese culinary staple food. Miso is high in protein and rich in vitamins and minerals, and it played an important nutritional role in feudal Japan. Miso is widely used in both traditional and modern cooking in Japan, and as of 2018 had been gaining worldwide interest.
A nutrient is a substance used by an organism to survive, grow and reproduce. The requirement for dietary nutrient intake applies to animals, plants, fungi and protists. Nutrients can be incorporated into cells for metabolic purposes or excreted by cells to create non-cellular structures such as hair, scales, feathers, or exoskeletons. Some nutrients can be metabolically converted into smaller molecules in the process of releasing energy such as for carbohydrates, lipids, proteins and fermentation products leading to end-products of water and carbon dioxide. All organisms require water. Essential nutrients for animals are the energy sources, some of the amino acids that are combined to create proteins, a subset of fatty acids, vitamins and certain minerals. Plants require more diverse minerals absorbed through roots, plus carbon dioxide and oxygen absorbed through leaves. Fungi live on dead or living organic matter and meet nutrient needs from their host.
Potassium is the main intracellular ion for all types of cells, while having a major role in maintenance of fluid and electrolyte balance. Potassium is necessary for the function of all living cells and is thus present in all plant and animal tissues. It is found in especially high concentrations within plant cells, and in a mixed diet, it is most highly concentrated in fruits. The high concentration of potassium in plants, associated with comparatively very low amounts of sodium there, historically resulted in potassium first being isolated from the ashes of plants (potash), which in turn gave the element its modern name. The high concentration of potassium in plants means that heavy crop production rapidly depletes soils of potassium, and agricultural fertilizers consume 93% of the potassium chemical production of the modern world economy.
Phytochemicals are chemical compounds produced by plants, generally to help them resist fungi, bacteria and plant virus infections, and also consumption by insects and other animals. The name comes from Greek φυτόν (phyton) 'plant'. Some phytochemicals have been used as poisons and others as traditional medicine.
Petasites is a genus of flowering plants in the sunflower family, Asteraceae, that are commonly referred to as butterburs and coltsfoots. They are perennial plants with thick, creeping underground rhizomes and large rhubarb-like leaves during the growing season. Most species are native to Asia or southern Europe.
Flammulina filiformis, commonly called enoki mushroom, is a species of edible agaric in the family Physalacriaceae. It is widely cultivated in East Asia, and well known for its role in Japanese and Chinese cuisine. Until recently, the species was considered to be conspecific with the European Flammulina velutipes, but DNA sequencing has shown that the two are distinct.
Tussilago farfara, commonly known as coltsfoot, is a plant in the tribe Senecioneae in the family Asteraceae, native to Europe and parts of western and central Asia. The name "tussilago" is derived from the Latin tussis, meaning cough, and ago, meaning to cast or to act on. It has had uses in traditional medicine, but the discovery of toxic pyrrolizidine alkaloids in the plant has resulted in liver health concerns.
Petasites frigidus, the Arctic sweet coltsfoot or Arctic butterbur, is a species of flowering plant in the family Asteraceae. It is native to Arctic to cool temperate regions of the Northern Hemisphere in northern Europe, northern Asia and northern North America.
Petasites hybridus, also known as the butterbur, is a herbaceous perennial flowering plant in the family Asteraceae that is native to Europe and northern Asia.
Guaraná Antarctica is a guaraná-flavoured soft drink, originating in Brazil. It was created in 1921 by Pedro Baptista de Andrade for Companhia Antarctica Paulista. The drink is produced in five countries: Portugal, Brazil, Argentina, Bolivia and Japan.
Arctium lappa, commonly called greater burdock, gobō (牛蒡/ゴボウ), edible burdock, lappa, beggar's buttons, thorny burr, or happy major is a Eurasian species of plants in the family Asteraceae, cultivated in gardens for its root used as a vegetable. It has become an invasive weed of high-nitrogen soils in North America, Australia, and other regions.
Glebionis coronaria, formerly called Chrysanthemum coronarium, is a species of flowering plant in the family Asteraceae. It is native to the Mediterranean region. It is cultivated and naturalized in East Asia and in scattered locations in North America.
Pyrrolizidine alkaloids (PAs), sometimes referred to as necine bases, are a group of naturally occurring alkaloids based on the structure of pyrrolizidine. Their use dates back centuries and is intertwined with the discovery, understanding, and eventual recognition of their toxicity on humans and animals.
Breynia androgyna, also known as katuk, star gooseberry, or sweet leaf, is a shrub grown in some tropical regions as a leaf vegetable. Its multiple upright stems can reach heights of 2.5 meters and bear dark green oval leaves of length 5–6 centimetres.
Dry cocoa solids are the components of cocoa beans remaining after cocoa butter, the fatty component of the bean, is extracted from chocolate liquor, roasted cocoa beans that have been ground into a liquid state. Cocoa butter is 46% to 57% of the weight of cocoa beans and gives chocolate its characteristic melting properties. Cocoa powder is the powdered form of the dry solids with a small remaining amount of cocoa butter. Untreated cocoa powder is bitter and acidic. Dutch process cocoa has been treated with an alkali to neutralize the acid.
A co-carcinogen is a chemical that promotes the effects of a carcinogen in the production of cancer. Usually, the term is used to refer to chemicals that are not carcinogenic on their own, such that an equivalent amount of the chemical is insufficient to initiate carcinogenesis. A chemical can be co-carcinogenic with other chemicals or with nonchemical carcinogens, such as UV radiation.
Fisetin (7,3′,4′-flavon-3-ol) is a plant flavonol from the flavonoid group of polyphenols. It can be found in many plants, where it serves as a yellow/ochre colouring agent. It is also found in many fruits and vegetables, such as strawberries, apples, persimmons, onions and cucumbers. Its chemical formula was first described by Austrian chemist Josef Herzig in 1891.
Riddelliine is a chemical compound classified as a pyrrolizidine alkaloid. It was first isolated from Senecio riddellii and is also found in a variety of plants including Jacobaea vulgaris, Senecio vulgaris, and others plants in the genus Senecio.
Mackerel is an important food fish that is consumed worldwide. As an oily fish, it is a rich source of omega-3 fatty acids. The flesh of mackerel spoils quickly, especially in the tropics, and can cause scombroid food poisoning. Accordingly, it should be eaten on the day of capture, unless properly refrigerated or cured.
Gynura bicolor, hongfeng cai 紅鳳菜, Okinawan spinach or edible gynura, is a member of the chrysanthemum family (Asteraceae). It is native to China, Thailand, and Myanmar but grown in many other places as a vegetable and as a medicinal herb.
