List Of Plants Poisonous To Equines
Many plants are poisonous to equines; the species vary depending on location, climate, and grazing conditions. In many cases, entire genera are poisonous to equines and include many species spread over several continents. Plants can cause reactions ranging from laminitis (found in horses bedded on shavings from black walnut trees), anemia, kidney disease and kidney failure (from eating the wilted leaves of red maples), to cyanide poisoning (from the ingestion of plant matter from members of the genus ''Prunus'') and other symptoms. Members of genus ''Prunus'' have also been theorized to be at fault for mare reproductive loss syndrome. Some plants, including yews, are deadly and extremely fast-acting. Several plants, including nightshade, become more toxic as they wilt and die, posing a danger to horses eating dried hay or plant matter blown into their pastures. The risk of animals becoming ill during the fall is increased, as many plants slow their growth in preparation for winte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Echium Plantagineum2
''Echium'' is a genus of approximately 70 species and several subspecies of flowering plant in the family (biology), family Boraginaceae. Species of ''Echium'' are native plant, native to North Africa, mainland Europe to Central Asia, and the Macaronesia, Macaronesian islands where the genus reaches its maximum diversity. 29 species of ''Echium'' are endemic to the Canary, Madeira, and Cape Verde archipelagos. The continental species are herbaceous, whereas all but two of the endemic species of the Macaronesian islands are woody perennial shrubs. Etymology The Latin genus name ''echium'' comes from the Greek language, Greek ''echion'' referring to Echium plantagineum and itself deriving from ''echis'' "viper"; the Greek term dates to Dioscorides who noted a resemblance between the shape of the nutlets to a viper’s head. The genus Echium was published by Carl Linnaeus in 1753. Cultivation and uses Many species are used as ornamental and garden plants and may be found i ...

Nerium Oleander
''Nerium oleander'' ( ), most commonly known as oleander or nerium, is a shrub or small tree cultivated worldwide in temperate and subtropical areas as an ornamental and landscaping plant. It is the only species currently classified in the genus ''Nerium'', belonging to subfamily Apocynoideae of the dogbane family Apocynaceae. It is so widely cultivated that no precise region of origin has been identified, though it is usually associated with the Mediterranean Basin. Nerium grows to tall. It is most commonly grown in its natural shrub form, but can be trained into a small tree with a single trunk. It is tolerant to both drought and inundation, but not to prolonged frost. White, pink or red five-lobed flowers grow in clusters year-round, peaking during the summer. The fruit is a long narrow pair of follicles, which splits open at maturity to release numerous downy seeds. Nerium contains several toxic compounds, and it has historically been considered a poisonous plant. Howeve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artemisia (genus)
''Artemisia'' () is a large, diverse genus of plants with between 200 and 400 species belonging to the daisy family Asteraceae. Common names for various species in the genus include mugwort, wormwood, and sagebrush. ''Artemisia'' comprises hardy herbaceous plants and shrubs, which are known for the powerful chemical constituents in their essential oils. ''Artemisia'' species grow in temperate climates of both hemispheres, usually in dry or semiarid habitats. Notable species include '' A. vulgaris'' (common mugwort), '' A. tridentata'' (big sagebrush), '' A. annua'' (sagewort), '' A. absinthium'' (wormwood), ''A. dracunculus'' (tarragon), and '' A. abrotanum'' (southernwood). The leaves of many species are covered with white hairs. Most species have strong aromas and bitter tastes from terpenoids and sesquiterpene lactones, which discourage herbivory, and may have had a selective advantage. The small flowers are wind-pollinated. ''Artemisia'' species are used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armoracia Lapathifolia
Horseradish (''Armoracia rusticana'', syn. ''Cochlearia armoracia'') is a perennial plant of the family Brassicaceae (which also includes Mustard plant, mustard, wasabi, broccoli, cabbage, and radish). It is a root vegetable, cultivated and used worldwide as a spice and as a condiment. The species is probably native to southeastern Europe and western Asia. Description Horseradish grows up to tall, with hairless bright green unlobed leaves up to long that may be mistaken for docks (''Rumex''). It is cultivated primarily for its large, white, tapered root. The white four-petalled flowers are scented and are borne in dense panicles. Established plants may form extensive patches and may become invasive unless carefully managed. Intact horseradish root has little aroma. When cut or grated, enzymes from within the plant cells digest sinigrin (a glucosinolate) to produce allyl isothiocyanate (mustard oil), which irritates the mucous membranes of the Paranasal sinus, sinuses and H ...
