Mentha Canadensis
''Mentha canadensis'' is a species of Mentha, mint native to North America (from the Northwest Territories to central Mexico) and the eastern part of Asia (from Siberia to Java). In North America, it is commonly known as Canada mint, American wild mint, and in Asia as Chinese mint, Sakhalin mint, Japanese mint, and East Asian wild mint. The flowers are bluish or have a slight violet tint. The plant is upright, growing to about tall. Leaves grow opposite from each other, and flower bunches appear in the upper leaf axils. The mint grows in wet areas but not directly in water, so it will be found near sloughs, and lake and river edges. Plants bloom from July to August in their native habitats. The plants found in eastern Asia have been called ''Mentha sachalinensis'', among other synonyms. Description ''Mentha canadensis'' is a perennial plant with an underground creeping rhizome and upright shoots. It can grow to a height of about . It has hairy stems bearing opposite pairs of le ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ...

Chromosome
A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones. These proteins, aided by chaperone proteins, bind to and condense the DNA molecule to maintain its integrity. These chromosomes display a complex three-dimensional structure, which plays a significant role in transcriptional regulation. Chromosomes are normally visible under a light microscope only during the metaphase of cell division (where all chromosomes are aligned in the center of the cell in their condensed form). Before this happens, each chromosome is duplicated ( S phase), and both copies are joined by a centromere, resulting either in an X-shaped structure (pictured above), if the centromere is located equatorially, or a two-arm structure, if the centromere is located distally. The joined copies are now called si ...

Flora Of Asia
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ...

Flora Of North America
The ''Flora of North America North of Mexico'' (usually referred to as ''FNA'') is a multivolume work describing the native plants and naturalized plants of North America, including the United States, Canada, St. Pierre and Miquelon, and Greenland. It includes bryophytes and vascular plants. All taxa are described and included in dichotomous keys, distributions of all species and infraspecific taxa are mapped, and about 20% of species are illustrated with line drawings prepared specifically for FNA. It is expected to fill 30 volumes when completed and will be the first work to treat all of the known flora north of Mexico; in 2015 it was expected tha the series would conclude in 2017. Twenty-nine of the volumes have been published as of 2022. Soon after publication, the contents are made available online. FNA is a collaboration of about 1,000 authors, artists, reviewers, and editors from throughout the world. Reception The series has been praised for "the comprehensive treatme ...

Drosophila Melanogaster
''Drosophila melanogaster'' is a species of fly (the taxonomic order Diptera) in the family Drosophilidae. The species is often referred to as the fruit fly or lesser fruit fly, or less commonly the "vinegar fly" or "pomace fly". Starting with Charles W. Woodworth's 1901 proposal of the use of this species as a model organism, ''D. melanogaster'' continues to be widely used for biological research in genetics, physiology, microbial pathogenesis, and life history evolution. As of 2017, five Nobel Prizes have been awarded to drosophilists for their work using the insect. ''D. melanogaster'' is typically used in research owing to its rapid life cycle, relatively simple genetics with only four pairs of chromosomes, and large number of offspring per generation. It was originally an African species, with all non-African lineages having a common origin. Its geographic range includes all continents, including islands. ''D. melanogaster'' is a common pest in homes, restaurants, and othe ...

Mint Herbal Tea
Mint tea is a herbal tea made by infusing mint leaves in hot water. Mint tea made with peppermint leaves is called peppermint tea, and mint tea made with spearmint is called spearmint tea. There also exist teas that infuse peppermint and spearmint leaves. In Korea, traditional mint tea called ''bakha-cha'' () is made with East Asian wild mint leaves. Due to the high content of essential oils in leaves (1–2.5%), especially menthol, mint tea is popular for its curative effects. Affecting the digestive system and excretion of gastric juices, it is thought to act as an anti-inflammatory.

Fragrance Oil
Fragrance oils, also known as aroma oils, aromatic oils, and flavor oils, are blended synthetic aroma compounds or natural essential oils that are diluted with a carrier like propylene glycol, vegetable oil, or mineral oil. To allergic or otherwise sensitive people, synthetic fragrance oils are often less desirable than plant-derived essential oils as components of perfume. Essential oils, widely used in society, emit numerous volatile organic compounds (VOCs). Some of these VOCs are considered as potentially hazardous under federal regulations However, synthetic versions of the same compound as a natural essential oil are usually very comparable. Furthermore, natural oils are in many cases significantly more expensive than their synthetic equivalents. Aromatic oils are used in perfumery, candles, cosmetics, flavoring of food. Some include (out of a very diverse range): * Ylang ylang * Vanilla * Sandalwood * Cedar wood * Mandarin orange * Cinnamon * Lemongrass * Rosehip * Pepperm ...

Peppermint
Peppermint (''Mentha'' × ''piperita'') is a hybrid species of mint, a cross between watermint and spearmint. Indigenous to Europe and the Middle East, the plant is now widely spread and cultivated in many regions of the world.Euro+Med Plantbase Project''Mentha'' × ''piperita''/ref> It is occasionally found in the wild with its parent species.Flora of NW Europe''Mentha'' × ''piperita'' Although the genus ''Mentha'' comprises more than 25 species, the one in most common use is peppermint. While Western peppermint is derived from ''Mentha × piperita'', Chinese peppermint, or ''bohe'', is derived from the fresh leaves of ''M. haplocalyx''. ''M. × piperita'' and ''M. haplocalyx'' are both recognized as plant sources of menthol and menthone, and are among the oldest herbs used for both culinary and medicinal products. Botany Peppermint was first described in 1753 by Carl Linnaeus from specimens that had been collected in England; he treated it as a species,Linnaeus, C. (17 ...

Pulegone
Pulegone is a naturally occurring organic compound obtained from the essential oils of a variety of plants such as ''Nepeta cataria'' (catnip), ''Mentha piperita'', and pennyroyal. It is classified as a monoterpene. Pulegone is a clear colorless oily liquid and has a pleasant odor similar to pennyroyal, peppermint and camphor. It is used in flavoring agents, in perfumery, and in aromatherapy. Toxicology It was reported that the chemical is toxic to rats if a large quantity is consumed. Pulegone is also an insecticide − the most powerful of three insecticides naturally occurring in many mint species. As of October 2018, the FDA withdrew authorization for the use of pulegone as a synthetic flavoring substance for use in food, but that naturally-occurring pulegone can continue to be used.

Menthol
Menthol is an organic compound, more specifically a monoterpenoid, made synthetically or obtained from the oils of corn mint, peppermint, or other mints. It is a waxy, clear or white crystalline substance, which is solid at room temperature and melts slightly above. The main form of menthol occurring in nature is (−)-menthol, which is assigned the (1''R'',2''S'',5''R'') configuration. Menthol has local anesthetic and counterirritant qualities, and it is widely used to relieve minor throat irritation. Menthol also acts as a weak κ-opioid receptor agonist. Structure Natural menthol exists as one pure stereoisomer, nearly always the (1''R'',2''S'',5''R'') form (bottom left corner of the diagram below). The eight possible stereoisomers are: : In the natural compound, the isopropyl group is in the ''trans'' orientation to both the methyl and hydroxyl groups. Thus, it can be drawn in any of the ways shown: : The (+)- and (−)-enantiomers of menthol are the most stable among ...
