Epimedium
''Epimedium'', also known as barrenwort, bishop's hat, fairy wings, horny goat weed, or yin yang huo (), is a genus of flowering plants in the family Berberidaceae. The majority of the species are endemic to China, with smaller numbers elsewhere in Asia, and a few in the Mediterranean region. ''Epimedium'' species are deciduous or evergreen hardy perennials. The majority have four-parted "spider-like" flowers in spring. The species used as a dietary supplement is '' Epimedium grandiflorum''. It contains icariin, which is a weak PDE5 inhibitor, ''in vitro''. Its clinical effects are unknown. While there is little clinical evidence to date, as sildenafil, vardenafil, and tadalafil – sold under the brand names Viagra, Levitra and Cialis – are all based on (stronger) PDE5 inhibitory action, it is thought to have erectogenic properties and is found in some men's sexual health supplements.

Epimedium Grandiflorum
''Epimedium grandiflorum'', the large flowered barrenwort, or bishop's hat, is a species of flowering plant in the family (biology), family ''Berberidaceae'', native plant, native to Japan and Korea. Description It is a deciduous perennial plant, perennial growing to , with bright red stems with green heart-shaped leaves (copper-tinged when young) which are slightly hairy on the bottom. In spring it produces pink, white, yellow or purple long-spurred flowers. The Latin specific epithet ''grandiflorum'' means large-flowered. Cultivation Numerous cultivars have been selected for garden use, of which the following have gained the Royal Horticultural Society's Award of Garden Merit: *''E. grandiflorum'' 'Akagi-Zakura' *''E. grandiflorum'' 'Circe' Use It is commonly packed in a capsule with other ingredients or sold as herbal flakes or powder with the name "horny goat weed".

Epimedium Alpinum
''Epimedium alpinum'', the alpine barrenwort, is a species of flowering plant in the genus ''Epimedium'', native to the mountains of Italy, Austria, the former Yugoslavia, and Albania, and introduced into central Europe. A dwarf perennial suitable for rock gardens, it was jocularly said by John Lindley to be "known only in the gardens of botanists". Its hybrid with ''Epimedium grandiflorum, E.grandiflorum'', ''Epimedium × rubrum'', has gained the Royal Horticultural Society's Award of Garden Merit.

Icariin
Icariin is a chemical compound classified as a prenylated flavonol glycoside, a type of flavonoid. It is the 8-prenyl derivative of kaempferol 3,7-''O''-diglucoside. The compound has been isolated from several species of plant belonging to the genus ''Epimedium'' which are commonly known as horny goat weed, Yin Yang Huo, and ''Herba epimedii''. Extracts from these plants produce aphrodisiac effects, and are used in traditional Chinese medicine Traditional Chinese medicine (TCM) is an alternative medicine, alternative medical practice drawn from traditional medicine in China. A large share of its claims are pseudoscientific, with the majority of treatments having no robust evidence ... to enhance erectile function.

Berberidaceae
The Berberidaceae are a family (biology), family of 18 genera of flowering plants commonly called the barberry family. This family is in the order (biology), order Ranunculales. The family contains about 700 known species, of which the majority are in the genus ''Berberis''. The species include trees, shrubs and perennial plant, perennial herbaceous plants. Taxonomy The APG IV system of 2016 recognises the family and places it in the order Ranunculales in the clade eudicots. In some older treatments of the family, Berberidaceae only included four genera (''Berberis, Epimedium, Mahonia, Vancouveria''), with the other genera treated in separate families, Leonticaceae (''Bongardia, Caulophyllum, Gymnospermium, Leontice''), Nandinaceae (''Nandina''), and Podophyllaceae (''Achlys, Diphylleia, Dysosma, Jeffersonia, Podophyllum, Ranzania, Sinopodophyllum''). ''Mahonia'' is very closely related to ''Berberis'', and included in it by many botanists. However, recent DNA-based Phylogeneti ...

Raceme
A raceme () or racemoid is an unbranched, indeterminate growth, indeterminate type of inflorescence bearing flowers having short floral stalks along the shoots that bear the flowers. The oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. Examples of racemes occur on mustard (genus ''Brassica''), radish (genus ''Raphanus''), and orchid (genus ''Phalaenopsis'') plants. Definition A ''raceme'' or ''racemoid'' is an unbranched, indeterminate growth, indeterminate type of inflorescence bearing pedicellate flowers (flowers having short floral stalks called ''Pedicel (botany), pedicels'') along its axis. In botany, an ''axis'' means a shoot, in this case one bearing the flowers. In indeterminate inflorescence-like racemes, the oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. A plant that flowers on a showy raceme may hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inflorescence
In botany, an inflorescence is a group or cluster of flowers arranged on a plant's Plant stem, stem that is composed of a main branch or a system of branches. An inflorescence is categorized on the basis of the arrangement of flowers on a main axis (Peduncle (botany), peduncle) and by the timing of its flowering (determinate and indeterminate). Morphology (biology), Morphologically, an inflorescence is the modified part of the Shoot (botany), shoot of spermatophyte, seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internode (botany), internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. General characteristics Inflorescences are described by many different charact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perennial
In horticulture, the term perennial ('' per-'' + '' -ennial'', "through the year") is used to differentiate a plant from shorter-lived annuals and biennials. It has thus been defined as a plant that lives more than 2 years. The term is also loosely used to distinguish plants with little or no woody growth (secondary growth in girth) from trees and shrubs, which are also technically ''perennials''. Notably, it is estimated that 94% of plant species fall under the category of perennials, underscoring the prevalence of plants with lifespans exceeding two years in the botanical world. Perennials (especially small flowering plants) that grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as herbaceous perennials. However, depending on the rigours of the local climate (temperature, moisture, organic content in the soil, microorganisms), a plant that is a peren ...
