Apocynum Pictum
''Apocynum'', commonly known as dogbane or Indian hemp, is a small genus of the flowering plant family Apocynaceae. Its name comes from Ancient Greek , from "away" and "dog", referring to dogbane ('' Cionura erecta''), which was used to poison dogs. The genus is native to North America, temperate Asia, and southeastern Europe. ''Apocynum'' species are used as food plants by the larvae of some Lepidoptera species, including the mouse moth and the queen butterfly. Uses ''Apocynum cannabinum'' was used as a source of fiber by Native Americans. '' Apocynum venetum'' () is used as an herbal tea in China. Dogbane contains cymarin, a cardiotonic agent formerly used to treat cardiac arrhythmia in humans. Species Almost 300 names have been proposed in the genus for species, subspecies, and forms. , only the following five species and hybrids are currently recognized, with several subspecies and varieties accepted for '' A. androsaemifolium'' and '' A. venetum'' (see their res ...

Apocynum Cannabinum
''Apocynum cannabinum'' (dogbane, amy root, hemp dogbane, prairie dogbane, Indian hemp, rheumatism root, or wild cotton) is a perennial herbaceous plant that grows throughout much of North America—in the southern half of Canada and throughout the United States. It is poisonous to humans, dogs, cats, and horses. All parts of the plant are toxic and can cause cardiac arrest if ingested. Some Lepidoptera feed on this plant, such as a hummingbird moth. Description ''Apocynum cannabinum'' grows up to tall. The stems are reddish and contain a milky latex. The leaves are opposite, simple broad lanceolate, long and broad, entire, and smooth on top with white hairs on the underside.

Hybrid Name
In botanical nomenclature, a hybrid may be given a hybrid name, which is a special kind of botanical name, but there is no requirement that a hybrid name should be created for plants that are believed to be of hybrid origin. The '' International Code of Nomenclature for algae, fungi, and plants'' (ICNafp) provides the following options in dealing with a hybrid: * A hybrid may get a name; this will usually be the option of choice for naturally occurring hybrids. * A hybrid may also be indicated by a formula listing the parents. Such a formula uses the multiplication sign "×" to link the parents. ** "It is usually preferable to place the names or epithets in a formula in alphabetical order. The direction of a cross may be indicated by including the sexual symbols (♀: female; ♂: male) in the formula, or by placing the female parent first. If a non-alphabetical sequence is used, its basis should be clearly indicated." (H.2A.1) * Grex names can be given to orchid hybrids. A hybrid ...

Cardiac Arrhythmia
Arrhythmias, also known as cardiac arrhythmias, heart arrhythmias, or dysrhythmias, are irregularities in the heartbeat, including when it is too fast or too slow. A resting heart rate that is too fast – above 100 beats per minute in adults – is called tachycardia, and a resting heart rate that is too slow – below 60 beats per minute – is called bradycardia. Some types of arrhythmias have no symptoms. Symptoms, when present, may include palpitations or feeling a pause between heartbeats. In more serious cases, there may be lightheadedness, passing out, shortness of breath or chest pain. While most cases of arrhythmia are not serious, some predispose a person to complications such as stroke or heart failure. Others may result in sudden death. Arrhythmias are often categorized into four groups: extra beats, supraventricular tachycardias, ventricular arrhythmias and bradyarrhythmias. Extra beats include premature atrial contractions, premature ventricular contra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Herbal Tea
Herbal teas, also known as herbal infusions and less commonly called tisanes (UK and US , US also ), are beverages made from the infusion or decoction of herbs, spices, or other plant material in hot water. Oftentimes herb tea, or the plain term ''tea'', is used as a reference to all sorts of herbal teas. Many herbs are used in herbal medicine. Some herbal blends contain actual tea (e.g., the Indian classic masala chai). The term "herbal" tea is often used in contrast to the so-called ''true'' teas (e.g., black, green, white, yellow, oolong), which are prepared from the cured leaves of the tea plant, '' Camellia sinensis''. Unlike true teas (which are also available decaffeinated), most tisanes do not naturally contain caffeine. There are a number of plants, however, that ''do'' contain caffeine or another stimulant, like theobromine, cocaine or ephedrine. Some have the opposite effect, acting as a sedative. Some common infusions have specific names such as , ''mate'' (ye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
