Heimia
''Heimia'' is a genus of flowering plants in the loosestrife family, Lythraceae. It contains two or three species of closely related shrubs commonly known as sun opener or shrubby yellowcrest. They are native to the Americas, from northern Argentina north to the southernmost United States (southern Texas). The leaves are 2–5 cm long and 1 cm broad, entire, and variably arranged alternate, opposite or whorled on the stems. All species produce five-petaled yellow flowers. The plants have a history of medicinal use in a variety of American cultures. Several pharmacologically active alkaloids have been detected in the plants. The generic names honours German physician Ernst Ludwig Heim (1747–1834). Species The genus contains three species. They are similar to the extent that expert knowledge is required to differentiate between specimens of the different species. The alkaloid contents of specimens of all three species has been studied, and although similar, they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Heimia Salicifolia
''Heimia salicifolia'' is a species of flowering plant in the Lythrum, Loosestrife family, Lythraceae. It is native to the Americas, ranging from the southwestern United States (Texas and New Mexico) through Mexico and Central America to Argentina. Common names include shrubby yellowcrest, sinicuichi, sun opener, willow-leaf heimia, sini. The plant has been used for shamanic purposes by native peoples in Central America and Mexico. Isolated alkaloids * Vertine, also known as cryogenine, is regarded as the primary bioactive component and is also generally the most abundant constituent of alkaloidal extracts. * Lyfoline, the second most abundant alkaloid * Lythrine, the third most abundant alkaloid * Heimidine, a minor alkaloid * Lythridine, a minor alkaloid Spiritual use Use of ''H. salicifolia'' for shamanic purposes by native peoples of Central America and Mexico has been described. In the method of preparation commonly used, fresh leaves are collected and allowed to wilt. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cryogenine
Cryogenine, also known as vertine or (10α)-4,5-dimethoxy-2-hydroxylythran-12-one, is a biphenylquinolizidine lactone alkaloid from the plants Sinicuichi (''Heimia salicifolia'') and '' H. myrtifolia''. The compound has no psychoactive properties in humans up to 310 mg, but has shown anti-inflammatory activity similar to aspirin. The freebase form melts at 250–251 °C and is soluble in moderately polar organic solvents such as chloroform, methylene chloride, benzene, and methanol, but is insoluble in water and petroleum ether. In the development of thin layer chromatography plates with diazotized p-nitroaniline spray, cryogenine produces a purple spot (as does sinicuichine, another biphenylquinolizidine lactone alkaloid found in ''Heimia ''Heimia'' is a genus of flowering plants in the loosestrife family, Lythraceae.

Ernst Ludwig Heim
Ernst Ludwig Heim (22 July 1747 – 15 September 1834) was a German physician and naturalist born in Solz, Thuringia. He was popular for providing free medical treatment in Berlin. As a naturalist Heim influenced Alexander von Humboldt and Christian Konrad Sprengel. Early life Heim was the son of pastor Johann Ludwig Heim (1704–1785). He went to Halle to study in 1766 and received his doctorate in 1772. He studied medicine, botany, astronomy, natural law and philosophy. He then served as (city physician) in Spandau (1776). He travelled across the Netherlands, France and England and visited hospitals and examined public health. Heim married Charlotte Maeker in 1780 and in April 1783 they moved to Berlin with their young daughter and lived at the Gendarmenmarkt. He opened a practice in Markgrafenstraße where he had a system of treating poor patients for free in the early morning. In 1799 he introduced smallpox vaccination in Berlin using cowpox inoculation based on Edward Je ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lythraceae
Lythraceae is a family of flowering plants, including 32 genera, with about 620 species of herbs, shrubs, and trees. The larger genera include ''Cuphea'' (275 spp.), ''Lagerstroemia'' (56), ''Nesaea'' (50), ''Rotala'' (45), and ''Lythrum'' (35). It also includes the pomegranate (''Punica granatum'', formerly in Punicaceae) and the water caltrop (''Trapa natans'', formerly in Trapaceae). Lythraceae has a worldwide distribution, with most species in the tropics, but ranging into temperate climate regions as well. The family is named after the type genus, ''Lythrum'', the loosestrifes (e.g. ''Lythrum salicaria'' purple loosestrife) and also includes henna (''Lawsonia inermis''). It now includes the pomegranate, formerly classed in a separate family Punicaceae. The family also includes the widely cultivated crape myrtle trees. Botanically, the leaves are usually in pairs (opposite), and the flower petals emerge from the rim of the calyx tube. The petals often appear crumpled. Ch ...
