Symphytum Tuberosum
''Symphytum tuberosum'', the tuberous comfrey, is a species of ''Symphytum'' in the family Boraginaceae. Species characteristics Tuberous comfrey flowers from April to June, however it also reproduces asexually, that is vegetatively, having rhizomes that allow it to spread out from the original site, colonising and competing as it grows. This process continues into the autumn and the young clonal plants can be seen at this time of year, whilst the parent plants leaves are rotting down. Being very hardy, this plant is well able to survive northern winters. Both the stems and leaves are softly hairy, the leaves have deep veining. The flowers themselves are a subtle pale creamy yellow, a significant characteristic for separating its identity from the purple flowered Russian Comfrey. The usual pollinators are the common carder bumble bee, honey bee A honey bee (also spelled honeybee) is a eusocial flying insect within the genus ''Apis'' of the bee clade, all native to Af ...

Saponin
Saponins (Latin "sapon", soap + "-in", one of), also selectively referred to as triterpene glycosides, are bitter-tasting usually toxic plant-derived organic chemicals that have a foamy quality when agitated in water. They are widely distributed but found particularly in soapwort (genus Saponaria), a flowering plant, the soapbark tree (''Quillaja saponaria'') and soybeans (''Glycine max'' L.). They are used in soaps, medicinals, fire extinguishers, speciously as dietary supplements, for synthesis of steroids, and in carbonated beverages (the head on a mug of root beer). Structurally, they are glycosides, sugars bonded to another organic molecule, usually a steroid or triterpene, a steroid building block. Saponins are both water and fat soluble, which gives them their useful soap properties. Some examples of these chemicals are glycyrrhizin, licorice flavoring; and quillaia (alt. quillaja), a bark extract used in beverages. Uses The saponins are a subclass of terpenoids, the larges ...

Mucilage
Mucilage is a thick, gluey substance produced by nearly all plants and some microorganisms. These microorganisms include protists which use it for their locomotion. The direction of their movement is always opposite to that of the secretion of mucilage. It is a polar glycoprotein and an exopolysaccharide. Mucilage in plants plays a role in the storage of water and food, seed germination, and thickening membranes. Cacti (and other succulents) and flax seeds are especially rich sources of mucilage. Occurrence Exopolysaccharides are the most stabilising factor for microaggregates and are widely distributed in soils. Therefore, exopolysaccharide-producing "soil algae" play a vital role in the ecology of the world's soils. The substance covers the outside of, for example, unicellular or filamentous green algae and cyanobacteria. Amongst the green algae especially, the group Volvocales are known to produce exopolysaccharides at a certain point in their life cycle. It occurs in alm ...

Allantoin
Allantoin is a chemical compound with formula C4H6N4O3. It is also called 5-ureidohydantoin or glyoxyldiureide. It is a diureide of glyoxylic acid. Allantoin is a major metabolic intermediate in most organisms including animals, plants and bacteria. It is produced from uric acid, which itself is a degradation product of nucleic acids, by action of urate oxidase (uricase). The occurs as a natural mineral compound ( IMA symbol Aan). History Allantoin was first isolated in 1800 by the Italian physician Michele Francesco Buniva (1761–1834) and the French chemist Louis Nicolas Vauquelin, who mistakenly believed it to be present in the amniotic fluid. In 1821, the French chemist Jean Louis Lassaigne found it in the fluid of the allantois; he called it ''"l'acide allantoique"''. In 1837, the German chemists Friedrich Wöhler and Justus Liebig synthesized it from uric acid and renamed it "allantoïn". Animals Named after the allantois (an amniote embryonic excretory organ in whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phytochemical
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 . Some phytochemicals have been used as poisons and others as traditional medicine. As a term, ''phytochemicals'' is generally used to describe plant compounds that are under research with unestablished effects on health, and are not scientifically defined as essential nutrients. Regulatory agencies governing food labeling in Europe and the United States have provided guidance for industry to limit or prevent health claims about phytochemicals on food product or nutrition labels. Definition Phytochemicals are chemicals of plant origin. Phytochemicals (from Greek ''phyto'', meaning "plant") are chemicals produced by plants through primary or secondary metabolism. They generally have biological activity in the plant host and play a role in plant growth or defense against competitors, p ...

Traditional Medicine
Traditional medicine (also known as indigenous medicine or folk medicine) comprises medical aspects of traditional knowledge that developed over generations within the folk beliefs of various societies, including indigenous peoples, before the era of modern medicine. The World Health Organization (WHO) defines traditional medicine as "the sum total of the knowledge, skills, and practices based on the theories, beliefs, and experiences indigenous to different cultures, whether explicable or not, used in the maintenance of health as well as in the prevention, diagnosis, improvement or treatment of physical and mental illness". Traditional medicine is often contrasted with scientific medicine. In some Asian and African countries, up to 80% of the population relies on traditional medicine for their primary health care needs. When adopted outside its traditional culture, traditional medicine is often considered a form of alternative medicine. Practices known as traditional medicines ...

Root Cutting
A plant cutting is a piece of a plant that is used in horticulture for vegetative reproduction, vegetative (asexual) plant propagation, propagation. A piece of the Plant stem, stem or root of the source plant is placed in a suitable medium such as moist soil. If the conditions are suitable, the plant piece will begin to grow as a new plant independent of the Mother plant, parent, a process known as striking. A stem cutting produces new roots, and a root cutting produces new stems. Some plants can be grown from leaf pieces, called leaf cuttings, which produce both stems and roots. The scions used in grafting are also called cuttings. Propagating plants from cuttings is an ancient form of cloning. There are several advantages of cuttings, mainly that the produced offspring are practically clones of their parent plants. If a plant has favorable traits, it can continue to pass down its advantageous genetic information to its offspring. This is especially economically advantageous as it ...

Bocking, Essex
Bocking is an area of Braintree, Essex, England, which was a former village and civil parish. In 1934 it became part of the civil parish of Braintree and Bocking, which is now within Braintree District. It forms an electoral division for Essex County Council elections, and gives its name to Bocking Blackwater, Bocking North and Bocking South wards of Braintree District Council. History In 1290 on 16 September, Bocking was visited by the Archbishop of Canterbury, John of Peckham, who there ordained to the priesthood William of Louth, bishop-elect of Ely. In 1381, on 4 June, Bocking was the site of the first sit-down discussions between rebels leading to the full Peasants' Revolt, and the subsequent march towards London.

Henry Doubleday (horticulturalist)
Henry Doubleday (1810-1902) was an English scientist and horticulturist of Coggeshall in Essex. __NOTOC__ Henry Doubleday was the son of William Doubleday and his wife Hannah Corder. His father was a shopkeeper in Coggeshall; the family were all Quakers. He lived at the same time as his cousin Henry Doubleday (1808-1875) the entomologist and ornithologist. Doubleday had a wide range of interests, in 1851 he won a bronze medal for lace designs made in Coggeshall and shown at the Great Exhibition. He gained the contract with De La Rue for the supply of gum arabic for postage stamps. Gum arabic is made from imported extracts from the acacia tree: in his efforts to find a suitable material which could be grown in England he experimented with imported varieties of comfrey, though the gum produced proved to be unsuitable. The value of his work was recognised and he was elected a member of the Royal Horticultural Society, however his membership was never registered as he was unable to af ...

Organic Gardening
Organic horticulture is the science and art of growing fruits, vegetables, flowers, or ornamental plants by following the essential principles of organic agriculture in soil building and conservation, pest management, and heirloom variety preservation. The Latin words ''hortus'' (garden plant) and ''cultura'' (culture) together form ''horticulture'', classically defined as the culture or growing of garden plants. ''Horticulture'' is also sometimes defined simply as "agriculture minus the plough". Instead of the plough, horticulture makes use of human labour and gardener's hand tools, although some small machine tools like rotary tillers are commonly employed now. General Mulches, cover crops, compost, manures, vermicompost, and mineral supplements are soil-building mainstays that distinguish this type of farming from its conventional counterpart. Through attention to good healthy soil condition, it is expected that insect, fungal, or other problems that sometimes plague plants ca ...
