Rhubarb (Peter Evrard Album)
Rhubarb is the fleshy, edible stalks ( petioles) of species and hybrids (culinary rhubarb) of '' Rheum'' in the family Polygonaceae, which are cooked and used for food. The plant is a herbaceous perennial that grows from short, thick rhizomes. Historically, different plants have been called "rhubarb" in English. The large, triangular leaves contain high levels of oxalic acid and anthrone glycosides, making them inedible. The small flowers are grouped in large compound leafy greenish-white to rose-red inflorescences. The precise origin of culinary rhubarb is unknown. The species '' Rheum rhabarbarum'' (syn. ''R. undulatum'') and '' R. rhaponticum'' were grown in Europe before the 18th century and used for medicinal purposes. By the early 18th century, these two species and a possible hybrid of unknown origin, ''R.'' × ''hybridum'', were grown as vegetable crops in England and Scandinavia. They readily hybridize, and culinary rhubarb was developed by sel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johan Andreas Murray
Johan Andreas (Anders) Murray (27 January 1740 – 22 May 1791) was a Swedish physician of German descent and botanist, who published a major work on plant-derived medicines. Biography Johan Anders Murray was born in Stockholm on 27 January 1740, son of the Prussian-born preacher and theologian Andreas Murray (1695 - 1771). His brothers were the professors Johann Philipp Murray (1726-1776) and Adolph Murray (1751-1803), and the Bishop Gustaf Murray (1747-1825). Murray studied from 1756-1759 in Uppsala, where he was taught by Carl Linnaeus. In 1760, he went to Göttingen, where he became a doctor of medicine in 1763. In 1769, he was appointed professor and director of the botanical garden. He led investigations into the properties of medicinal plants, at that time the main interest of botanists, and into the ways in which plant-derived medicines could be prepared and administered. In 1791, Murray was elected a member of the American Philosophical Society. Murray died in Gött ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Celery
Celery (''Apium graveolens'') is a marshland plant in the family Apiaceae that has been cultivated as a vegetable since antiquity. Celery has a long fibrous stalk tapering into leaves. Depending on location and cultivar, either its stalks, leaves or hypocotyl are eaten and used in cooking. Celery seed powder is used as a spice. Description Celery leaves are pinnate to bipinnate with rhombic leaflets long and broad. The flowers are creamy-white, in diameter, and are produced in dense compound umbels. The seeds are broad ovoid to globose, long and wide. Modern cultivars have been selected for either solid petioles, leaf stalks, or a large hypocotyl. A celery stalk readily separates into "strings" which are bundles of angular collenchyma cells exterior to the vascular bundles. Wild celery, ''Apium graveolens'' var. ''graveolens'', grows to tall. Celery is a biennial plant that occurs around the globe. It produces flowers and seeds only during its second year. The first cul ...

Greenhouse
A greenhouse (also called a glasshouse, or, if with sufficient heating, a hothouse) is a structure with walls and roof made chiefly of Transparent ceramics, transparent material, such as glass, in which plants requiring regulated climatic conditions are grown.These structures range in size from small sheds to industrial-sized buildings. A miniature greenhouse is known as a cold frame. The interior of a greenhouse exposed to sunlight becomes significantly warmer than the external temperature, protecting its contents in cold weather. Many commercial glass greenhouses or hothouses are high tech production facilities for vegetables, flowers or fruits. The glass greenhouses are filled with equipment including screening installations, heating, cooling, and lighting, and may be controlled by a computer to optimize conditions for plant growth. Different techniques are then used to manage growing conditions, including air temperature, relative humidity and vapour-pressure deficit, in ord ...

Rheum Rhabarbarum (Rabarber) Frambozenrood Bloeiwijze
''Rheum rhabarbarum'' is a species of flowering plant in the family Polygonaceae, native to a region stretching from southern Siberia to north and central China. It has been harvested from the wild for centuries for its root, which was harvested for use as a popular medicine in Europe and Asia. It was later cultivated for its root in England and Russia. It is considered to be one of the species involved in the development of culinary rhubarb, for which the scientific name ''R. rhabarbarum'' is sometimes (erroneously) used. Taxonomy ''Rheum rhabarbarum'' was first described by Carl Linnaeus in 1753. Linnaeus also described ''R. undulatum'', but this is now considered to be the same species. The name ''rha barbarum'', Latin for 'foreign rha', was first used in the writings of Celsus, who uses the word to describe a valued medicinal root imported from the east. Description Similar species According to the 2003 key in the ''Flora of China'', this species is distinguished f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pontus (region)
Pontus or Pontos (; el, Πόντος, translit=Póntos, "Sea") is a region on the southern coast of the Black Sea, located in the modern-day eastern Black Sea Region of Turkey. The name was applied to the coastal region and its mountainous hinterland (rising to the Pontic Alps in the east) by the Greeks who colonized the area in the Archaic period and derived from the Greek name of the Black Sea: ''(')'', "Hospitable Sea", or simply ''Pontos'' () as early as the Aeschylean ''Persians'' (472 BC) and Herodotus' ''Histories'' (circa 440 BC). Having originally no specific name, the region east of the river Halys was spoken of as the country ''()'', lit. "on the uxinosPontos", and hence it acquired the name of Pontus, which is first found in Xenophon's ''Anabasis (Xenophon), Anabasis'' (). The extent of the region varied through the ages but generally extended from the borders of Colchis (modern western Georgia (country), Georgia) until well into Paphlagonia in the west, with ...

Galen
Aelius Galenus or Claudius Galenus ( el, Κλαύδιος Γαληνός; September 129 – c. AD 216), often Anglicized as Galen () or Galen of Pergamon, was a Greek physician, surgeon and philosopher in the Roman Empire. Considered to be one of the most accomplished of all medical researchers of antiquity, Galen influenced the development of various scientific disciplines, including anatomy, physiology, pathology, pharmacology, and neurology, as well as philosophy and logic. The son of Aelius Nicon, a wealthy Greek architect with scholarly interests, Galen received a comprehensive education that prepared him for a successful career as a physician and philosopher.

Pedanius Dioscorides
Pedanius Dioscorides ( grc-gre, Πεδάνιος Διοσκουρίδης, ; 40–90 AD), “the father of pharmacognosy”, was a Greek physician, pharmacologist, botanist, and author of ''De materia medica'' (, On Medical Material) —a 5-volume Greek encyclopedia about herbal medicine and related medicinal substances (a pharmacopeia), that was widely read for more than 1,500 years. For almost two millennia Dioscorides was regarded as the most prominent writer on plants and plant drugs. Life A native of Anazarbus, Cilicia, Asia Minor, Dioscorides likely studied medicine nearby at the school in Tarsus, Mersin, Tarsus, which had a pharmacological emphasis, and he dedicated his medical books to Laecanius Arius, a medical practitioner there. Though he writes he lived a "soldier's life" or "soldier-like life", his pharmacopeia refers almost solely to plants found in the Greek-speaking eastern Mediterranean, making it likely that he served in campaigns, or travelled in a civilian ca ...

Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine. Dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Old French
Old French (, , ; Modern French: ) was the language spoken in most of the northern half of France from approximately the 8th to the 14th centuries. Rather than a unified language, Old French was a linkage of Romance dialects, mutually intelligible yet diverse, spoken in the northern half of France. These dialects came to be collectively known as the , contrasting with the in the south of France. The mid-14th century witnessed the emergence of Middle French, the language of the French Renaissance in the Île de France region; this dialect was a predecessor to Modern French. Other dialects of Old French evolved themselves into modern forms (Poitevin-Saintongeais, Gallo, Norman, Picard, Walloon, etc.), each with its own linguistic features and history. The region where Old French was spoken natively roughly extended to the northern half of the Kingdom of France and its vassals (including parts of the Angevin Empire, which during the 12th century remained under Anglo-Norman rul ...
