Carl Ludwig Willdenow
Carl Ludwig Willdenow (22 August 1765 – 10 July 1812) was a German botanist, pharmacist, and plant taxonomist. He is considered one of the founders of phytogeography, the study of the geographic distribution of plants. Willdenow was also a mentor of Alexander von Humboldt, one of the earliest and best known phytogeographers. He also influenced Christian Konrad Sprengel, who pioneered the study of plant pollination and floral biology. Biography Willdenow was born in Berlin and studied medicine and botany at the University of Halle. After studying pharmaceutics at Wieglieb College, Langensalza and in medicine at Halle, he returned to Berlin to work at his father's pharmacy located in the Unter den Linden. His early interest in botany was kindled by his uncle J. G. Gleditsch and he started a herbarium collection in his teenage years. In 1794 he became a member of the Berlin Academy of Sciences. He was a director of the Botanical garden of Berlin from 1801 until his dea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polygalaceae
The Polygalaceae or the milkwort family are made up of flowering plants in the order Fabales. They have a near-cosmopolitan range, with about 27 genera and ''ca''. 900 known species of herbs, shrubs and trees. Over half of the species are in one genus, ''Polygala'', the milkworts. The family was first described in 1809 by Johann Hoffmansegg and Johann Link. In 1896, Robert Chodat split it into 3 tribes. A fourth tribe was split off from the tribe Polygaleae in 1992. Under the Cronquist classification system, Polygalaceae were treated in a separate order of their own, Polygalales. Currently, according to the Angiosperm Phylogeny Group, the family belongs in Fabales. Description ''Polygalaceae'' are annual or perennial herbs, shrubs, shrublets, and small trees. Its zygomorphic, hermaphrodite, bisexual flowers have 3-5 petals and 5 sepals. Its leaves are usually alternate, but may be opposite, fascicled, or verticillate. Each flower usually cont ...

Plant Hardiness Zone
A hardiness zone is a geographic area defined as having a certain average annual minimum temperature, a factor relevant to the survival of many plants. In some systems other statistics are included in the calculations. The original and most widely used system, developed by the United States Department of Agriculture (USDA) as a rough guide for landscaping and gardening, defines 13 zones by long-term average annual extreme minimum temperatures. It has been adapted by and to other countries (such as Canada) in various forms. Unless otherwise specified, in American contexts "hardiness zone" or simply "zone" usually refers to the USDA scale. For example, a plant may be described as "hardy to zone 10": this means that the plant can withstand a minimum temperature of 30 °F (−1.1 °C) to 40 °F (4.4 °C). Other hardiness rating schemes have been developed as well, such as the UK Royal Horticultural Society and US Sunset Western Garden Book systems. A heat zone (s ...

Mucolytic Agent
Mucoactive agents are a class of chemical agents that aid in the clearance of mucus or sputum from the upper and lower airways, including the lungs, bronchi, and trachea. Mucoactive drugs include expectorants, mucolytics, mucoregulators, and mucokinetics. These medications are used in the treatment of respiratory diseases that are complicated by the oversecretion or inspissation of mucus. These drugs can be further categorized by their mechanism of action. Mechanism of action Mucoactive agents - expectorants – include mucolytics, secretolytics and mucokinetics (also called secretomotorics) * Mucolytics – thin (reduce the viscosity of) mucus * Secretolytics – increase airway water or the volume of airway secretions * Mucokinetics – increase mucociliary transport (clearance) and transportability of mucus by cough * Mucoregulators – suppress underlying mechanisms of mucus hypersecretion Alternatively, attacking the affinity between secretions and the biological surfaces ...

Chinese Herbology
Chinese herbology () is the theory of traditional Chinese herbal therapy, which accounts for the majority of treatments in traditional Chinese medicine (TCM). A ''Nature (journal), Nature'' editorial described TCM as "fraught with pseudoscience", and said that the most obvious reason why it has not delivered many cures is that the majority of its treatments have no logical mechanism of action. The term herbology is misleading in the sense that, while plant elements are by far the most commonly used substances, animal, human, and mineral products are also utilized, among which some are poisonous. In the ''Huangdi Neijing'' they are referred to as () which means toxin, poison, or medicine. Paul U. Unschuld points out that this is similar etymology to the Greek ''Pharmakon (philosophy), pharmakon'' and so he uses the term "pharmaceutic". Thus, the term "medicinal" (instead of herb) is usually preferred as a translation for (). Research into the effectiveness of traditional Chine ...

Traditional Chinese Medicine
Traditional Chinese medicine (TCM) is an alternative medicine, alternative medical practice drawn from traditional medicine in China. It has been described as "fraught with pseudoscience", with the majority of its treatments having no logical mechanism of action. Medicine in traditional China encompassed a range of sometimes competing health and healing practices, folk beliefs, Scholar-official, literati theory and Confucianism, Confucian philosophy, Chinese herbology, herbal remedies, Chinese food therapy, food, diet, exercise, medical specializations, and schools of thought. In the early twentieth century, Chinese cultural and political modernizers worked to eliminate traditional practices as backward and unscientific. Traditional practitioners then selected elements of philosophy and practice and organized them into what they called "Chinese medicine" (''Zhongyi''). In the 1950s, the Chinese government sponsored the integration of Chinese and Western medicine, and in the G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
