Digitalis
''Digitalis'' ( or ) is a genus of about 20 species of herbaceous perennial plants, shrubs, and Biennial plant, biennials, commonly called foxgloves. ''Digitalis'' is native to Europe, Western Asia, and northwestern Africa. The flowers are tubular in shape, produced on a tall spike, and vary in colour with species, from purple to pink, white, and yellow. The name derives from the Latin word for "finger". The genus was traditionally placed in the figwort family, Scrophulariaceae, but phylogenetic research led taxonomists to move it to the Veronicaceae in 2001. More recent phylogenetic work has placed it in the much enlarged family Plantaginaceae. The best-known species is the common foxglove, ''Digitalis purpurea''. This biennial is often grown as an ornamental plant due to its vivid flowers, which range in colour from various purple tints through pink and purely white. The flowers can also possess various marks and spottings. Other garden-worthy species include ''D. ferrugi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Digitalis Purpurea
''Digitalis purpurea'', the foxglove or common foxglove, is a toxic species of flowering plant in the plantain family Plantaginaceae, native to and widespread throughout most of temperate Europe. It has also naturalized in parts of North America, as well as some other temperate regions. The plant is a popular garden subject, with many cultivars available. It is the original source of the heart medicine digoxin (also called digitalis or digitalin). This biennial plant grows as a rosette of leaves in the first year after sowing, before flowering and then dying in the second year (i.e., it is monocarpic). It generally produces enough seeds so that new plants will continue to grow in a garden setting. Description ''Digitalis purpurea'' is an herbaceous biennial or short-lived perennial plant. The leaves are spirally arranged, simple, long and broad, and are covered with gray-white pubescent and glandular hairs, imparting a woolly texture. The foliage forms a tight rosette ...

Digitalis Cariensis
''Digitalis cariensis'' is a type of foxglove and part of a flowering plant species in the family Plantaginaceae, native to southwestern to southern Turkey. In Muğla vilayet, it is locally known as ''yüksükotu'', which generally means 'foxglove' in the Turkish language. A more specific name for this species is ''ishalotu'', but the term may also be used for different plants. Taxonomy A certain Chr. Pinard travelled twice to the region of Caria in the Ottoman Empire, first in 1842 and again in 1843. He collected plant specimens and sent them to Swiss botanist Alphonse de Candolle, who duly passed them on to the greatest expert of the flora of the Near and Middle East at the time, Pierre Edmond Boissier, also a Swiss botanist. As such Pinard collected the first scientific samples of the species ''Digitalis cariensis'', as Boissier provisionally named it, in this region. Pinard sent a number of duplicates (especially in 1843), which could then be used to trade with other botani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digitalis Atlantica
''Digitalis atlantica'' is a species of perennial flowering plant in the family Plantaginaceae. It is native to Algeria. Description ''Digitalis atlantica'' is a biennial or perennial herb. The plant leaves grow in the shape of a rosette until flowering stems develop in the second year. Leaves are downy, finely wrinkled on the upper surface and grey-green. The leaves are ovate, with toothed edges, and may measure up to 25cm long. The flowering stem can grow up to 2m tall, with flowers in a tall spike during the flowering period of spring to summer. Toxicity Like all species in the ''Digitalis'' genus, ''Digitalis atlantica'' is also toxic. However, this particular species seems to have the lowest cardenolide A cardenolide is a type of steroid. Many plants contain derivatives, collectively known as cardenolides, including many in the form of cardenolide glycosides (cardenolides that contain structural groups derived from sugars).

Digoxin
Digoxin (better known as digitalis), sold under the brand name Lanoxin among others, is a medication used to treat various heart disease, heart conditions. Most frequently it is used for atrial fibrillation, atrial flutter, and heart failure. Digoxin is one of the oldest medications used in the field of cardiology. It works by increasing myocardial contractility, increasing stroke volume and blood pressure, reducing heart rate, and somewhat extending the time frame of the Muscle contraction, contraction. Digoxin is taken by mouth or by intravenous, injection into a vein. Digoxin has a half life of approximately 36 hours given at average doses in patients with normal renal function. It is excreted mostly unchanged in the urine. Common side effects include gynecomastia, breast enlargement with other side effects generally due to an excessive dose. These side effects may include loss of appetite, nausea, trouble seeing, confusion, and an Heart arrhythmia, irregular heartbeat. Gre ...

Digitalis Cedretorum
''Digitalis cedretorum'' is a species of flowering plant in the family Plantaginaceae that is native to Morocco. Taxonomy It was first described as ''Digitalis lutea'' subsp. ''cedretorum'' in 1936 by the French botanist Louis Emberger. Another French botanist, René Maire, raised it to an independent species four years later, 1940. It was first collected in a cedar woodland on a granite-derived substrate, at 2,500 metres in altitude in the eastern Atlas Mountains The Atlas Mountains are a mountain range in the Maghreb in North Africa. They separate the Sahara Desert from the Mediterranean Sea and the Atlantic Ocean; the name "Atlantic" is derived from the mountain range, which stretches around through M ..., north of a town called Masker.

Cardiac Glycoside
Cardiac glycosides are a class of organic compounds that increase the output force of the heart and decrease its rate of contractions by inhibiting the cellular sodium-potassium ATPase pump. Their beneficial medical uses include treatments for congestive heart failure and cardiac arrhythmias; however, their relative toxicity prevents them from being widely used. Most commonly found as defensive poisons in several plant genera such as ''Digitalis'' (the foxgloves) and '' Asclepias'' (the milkweeds), these compounds nevertheless have a diverse range of biochemical effects regarding cardiac cell function and have also been suggested for use in cancer treatment. Classification General structure The general structure of a cardiac glycoside consists of a steroid molecule attached to a sugar (glycoside) and an R group. The steroid nucleus consists of four fused rings to which other functional groups such as methyl, hydroxyl, and aldehyde groups can be attached to influence th ...

Veronicaceae
Plantaginaceae, the plantain family or veronica family, is a large, diverse family of flowering plants in the order Lamiales that includes common flowers such as snapdragon and foxglove. It is unrelated to the banana-like fruit also called "plantain". In older classifications, Plantaginaceae was the only family of the order Plantaginales, but numerous phylogenetic studies, summarized by the Angiosperm Phylogeny Group, have demonstrated that this taxon should be included within Lamiales. Overview The plantain family as traditionally circumscribed consisted of only three genera: ''Bougueria'', ''Littorella'', and ''Plantago''. However phylogenetic research has indicated that Plantaginaceae ''sensu stricto'' (in the strict sense) were nested within Scrophulariaceae (but forming a group that did not include the type genus of that family, ''Scrophularia''). Although Veronicaceae (1782) is the oldest family name for this group, Plantaginaceae (1789) is a conserved name under the Int ...

Scrophulariaceae
The Scrophulariaceae are a family of flowering plants, commonly known as the figwort family. The plants are annual and perennial herbs, as well as shrubs. Flowers have bilateral (zygomorphic) or rarely radial (actinomorphic) symmetry. The Scrophulariaceae have a cosmopolitan distribution, with the majority found in temperate areas, including tropical mountains. The family name is based on the name of the included genus ''Scrophularia'' L. Taxonomy In the past, it was treated as including about 275 genera and over 5,000 species, but its circumscription has been radically altered since numerous molecular phylogenies have shown the traditional broad circumscription to be grossly polyphyletic. Many genera have recently been transferred to other families within the Lamiales, notably Plantaginaceae and Orobanchaceae, but also several new families. - on linhere/ref> Several families of the Lamiales have had their circumscriptions enlarged to accommodate genera transferred from ...
