Chay Root
''Oldenlandia umbellata'' (called chay root or choy root, from its Tamil name, ''chaaya ver'') is a low-growing plant native to India. A colour-fast red dye can be extracted from the root bark of (preferably) a two-year-old plant. Chay root dye was once used with a mordant to impart a red colour to fabrics such as calico, wool, and silk. It is grown on the Coromandel Coast in India. Medicinal use This plant is well known in Siddha Medicine for its styptic property. It is also a drug that can be administered for bronchial asthma, as a decoction of the entire plant, a decoction made from its root and liquorice in the ratio-10:4, or the powdered root is given either with water or honey. A decoction of the root also is a febrifuge An antipyretic (, from ''anti-'' 'against' and ' 'feverish') is a substance that reduces fever. Antipyretics cause the hypothalamus to override a prostaglandin-induced increase in temperature. The body then works to lower the temperature, which r ... ...

Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was the son of a curate and was born in Råshult, in the countryside of Småland, 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 co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tamil Language
Tamil (, , , also written as ''Tamizhil'' according to linguistic pronunciation) is a Dravidian language natively spoken by the Tamil people of South Asia. It is one of the longest-surviving classical languages in the world,. "Tamil is one of the two longest-surviving classical languages in India" (p. 7). attested since 300 BC, 300 BCE.: "...the most acceptable periodisation which has so far been suggested for the development of Tamil writing seems to me to be that of A Chidambaranatha Chettiar (1907–1967): 1.

Mordant
A mordant or dye fixative is a substance used to set (i.e., bind) dyes on fabrics. It does this by forming a coordination complex with the dye, which then attaches to the fabric (or tissue). It may be used for dyeing fabrics or for intensifying stains in cell or tissue preparations. Although mordants are still used, especially by small batch dyers, they have been largely displaced in industry by substantive dyes.} The term mordant comes from the Latin ''mordere'', "to bite". In the past, it was thought that a mordant helped the dye "bite" onto the fiber so that it would hold fast during washing. A mordant is often a polyvalent metal ion, and one example is chromium (III). The resulting coordination complex of dye and ion is colloidal and can be either acidic or alkaline. Common dye mordants Mordants include tannic acid, oxalic acid, alum, chrome alum, sodium chloride, and certain salts of aluminium, chromium, copper, iron, iodine, potassium, sodium, tungsten, and tin.

Calico (textile)
Calico (; in British usage since 1505) is a heavy plain-woven textile made from unbleached, and often not fully processed, cotton. It may also contain unseparated husk parts. The fabric is far coarser than muslin, but less coarse and thick than canvas or denim. However, it is still very cheap owing to its unfinished and undyed appearance. The fabric was originally from the city of Calicut in southwestern India. It was made by the traditional weavers called cāliyans. The raw fabric was dyed and printed in bright hues, and calico prints became popular in Europe. History Origins Calico originated in Calicut, from which the name of the textile came, in South India, now Kerala, during the 11th century, where the cloth was known as "chaliyan". It was mentioned in Indian literature by the 12th century when the polymath and writer Hemachandra described calico fabric prints with a lotus design.''Encyclopædia Britannica'' (2008)"calico" Calico was woven using Gujarati cotton f ...

Wool
Wool is the textile fiber obtained from sheep and other mammals, especially goats, rabbits, and camelids. The term may also refer to inorganic materials, such as mineral wool and glass wool, that have some properties similar to animal wool. As an animal fiber, wool consists of protein together with a small percentage of lipids. This makes it chemically quite distinct from cotton and other plant fibers, which are mainly cellulose. Characteristics Wool is produced by follicles which are small cells located in the skin. These follicles are located in the upper layer of the skin called the epidermis and push down into the second skin layer called the dermis as the wool fibers grow. Follicles can be classed as either primary or secondary follicles. Primary follicles produce three types of fiber: kemp, medullated fibers, and true wool fibers. Secondary follicles only produce true wool fibers. Medullated fibers share nearly identical characteristics to hair and are long but ...

Silk
Silk is a natural fiber, natural protein fiber, some forms of which can be weaving, woven into textiles. The protein fiber of silk is composed mainly of fibroin and is most commonly produced by certain insect larvae to form cocoon (silk), cocoons. The best-known silk is obtained from the cocoons of the larvae of the mulberry silkworm ''Bombyx mori'' reared in captivity (sericulture). The shimmering appearance of silk is due to the triangular Prism (optics), prism-like structure of the silk fibre, which allows silk cloth to refract incoming light at different angles, thus producing different colors. Harvested silk is produced by several insects; but, generally, only the silk of various moth caterpillars has been used for textile manufacturing. There has been some research into other types of silk, which differ at the molecular level. Silk is mainly produced by the larvae of insects undergoing holometabolism, complete metamorphosis, but some insects, such as webspinners and Gr ...

Coromandel Coast
The Coromandel Coast is a coastal region along the southeastern front of the Indian peninsula. Its delimitations are numerous, but generally admitted to be bounded by the Krishna River, Krishna river River mouth, mouth to the north, the Bay of Bengal to the east, the Point Calimere Cape (geography), cape to the south, and the Eastern Ghats to the west. Some may definite its northern boundaries up to Ganjam. This region can be extending over an area of about 22,800 square kilometres. The coast has an average elevation of 80 metres and is backed by the Eastern Ghats, a chain of low lying and flat-topped hills. The land of the Chola dynasty was called Cholamandalam in Tamil language, Tamil, literally translated as "Mandala (political model), the realm of the Cholas", from which Coromandel is derived. In historical Muslim sources from the 12th century onward, the Coromandel Coast was notably called as Ma'bar Coast, Maʿbar Coast. Etymology The land of the Chola dynasty was called ...

Antihemorrhagic
An antihemorrhagic () agent is a substance that promotes hemostasis (a process which stops bleeding). It may also be known as a hemostatic (also spelled haemostatic) agent. Antihemorrhagic agents used in medicine have various mechanisms of action: * Systemic drugs work by inhibiting fibrinolysis or promoting coagulation. * Locally acting hemostatic agents work by causing vasoconstriction or promoting platelet aggregation. Medical uses Hemostatic agents are used during surgical procedures to achieve hemostasis and are categorized as hemostats, sealants and adhesives. They vary based on their mechanism of action, composition, ease of application, adherence to tissue, immunogenicity and cost. These agents permit rapid hemostasis, better visualization of the surgical area, shorter operative times, decreased requirement for transfusions, decreased wound healing time and overall improvement in patient recovery time. Types Systemic There are several classes of antihemorrhagic drug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asthma
Asthma is a common long-term inflammatory disease of the airways of the lungs. It is characterized by variable and recurring symptoms, reversible airflow obstruction, and easily triggered bronchospasms. Symptoms include episodes of wheezing, coughing, chest tightness, and shortness of breath. A sudden worsening of asthma symptoms sometimes called an 'asthma attack' or an 'asthma exacerbation' can occur when allergens, pollen, dust, or other particles, are inhaled into the lungs, causing the bronchioles to constrict and produce mucus, which then restricts oxygen flow to the alveoli. These may occur a few times a day or a few times per week. Depending on the person, asthma symptoms may become worse at night or with exercise. Asthma is thought to be caused by a combination of genetic and environmental factors. Environmental factors include exposure to air pollution and allergens. Other potential triggers include medications such as aspirin and beta blockers. Diag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Febrifuge
An antipyretic (, from ''anti-'' 'against' and ' 'feverish') is a substance that reduces fever. Antipyretics cause the hypothalamus to override a prostaglandin-induced increase in temperature. The body then works to lower the temperature, which results in a reduction in fever. Most antipyretic medications have other purposes. The most common antipyretics in the US are usually ibuprofen and aspirin, which are nonsteroidal anti-inflammatory drugs (NSAIDs) used primarily as anti-inflammatories and analgesics (pain relievers), but which also have antipyretic properties; and paracetamol (acetaminophen), an analgesic without anti-inflammatory properties. There is some debate over the appropriate use of such medications, since fever is part of the body's immune response to infection. A study published by the Royal Society claims that fever suppression causes at least 1% more influenza deaths in the United States, or 700 extra deaths per year.
