Epipactis, or Helleborine,
is a genus of terrestrial orchids consisting of approximately 70 species. This
genus is abbreviated as Epcts in horticultural trade.
They
occur in temperate and subtropical climates of America, Asia, and Europe. These orchids grow in
open spaces in forests, in undergrowth, on calcareous soils and are often found
in wet dune-slacks near the sea. The only original American species is Giant
Helleborine (Epipactis gigantea). One species from
Europe, Broad-leaved Helleborine (Epipactis helleborine), is invasive in North America. Most species are
protected.
Most
of these hardy orchids grow in a wet environment, but there are exceptions. The
Marsh helleborine (Epipactis palustris) is the only European
orchid able to survive in a flooded habitat. Epipactis gigantea is a species found
in the American west, and into southernCanada, in wet areas and even
streams. It can grow to a height of 1 m. However,Epipactis helleborine grows in more
diverse habitats, from sheltered sandy beaches to open spaces in deciduous or
coniferous forests, on roadsides, in meadows, and on moist soils. It is
sometimes called the Weed Orchid.
As
characteristic of all orchids, Epipactisspp. are dependent on
a mycorrhizal symbiosis (see also Orchid mycorrhiza). This allows some
species to have reduced leaves and need little chlorophyll. Violet Helleborine
(Epipactis viridiflora) can even do without chlorophyll. These forms can
be recognized by their purple instead of violet flowers.
Their
creeping, fleshy rhizomes grow offshoots,
from which then emerge the 20–70 cm long stems during the next spring.
There
are four to eight alternate, lanceolate leaves, that grow progressively
shorter near the top. The margins are entire, the top is acute. Species with
less chlorophyll have blue-purple
leaves.
Their
bilaterally symmetrical colorful flowers grow from a
terminal raceme. The three sepals and the two
lateral petals are ovate and
acuminate. Their color can vary from greenish-white to violet and purple.
The lip is divided in a
bowl-shaped hypochile, with the outer surface greenish-white and threaded with
dark veins. The wavy, snow-white epichile is fan-shaped.

species occurs in the Sarmatic
mixed forests ecoregion.[4]
This
species has a stem growing to 60 cm high with erect leaves up to
12 cm long. The flowers are 17 mm across arranged in a one-sided
raceme. In the typical form, the sepals are coloured deep pink or purplish-red,
the upper petals shorter and paler. The labellum at least as long as the
sepals, white with red or yellow spots in the middle.[5] Variants without
most of the reddish colours of the typical form have been called E. palustris var. ochroleuca.[6]

Epimedium, also known as barrenwort, bishop's
hat, fairy wings, horny goat weed, or yin
yang huo (Chinese: 淫羊藿), is a genus of flowering plantsin the family Berberidaceae. The majority of the
species are endemic to China, with smaller numbers
elsewhere in Asia, and a few in the Mediterraneanregion.[2]
Epimedium species are deciduous or evergreen hardy perennials. The majority have
four-parted "spider-like" flowers in spring.
The
plant[which?] contains icariin, which is a weak PDE5 inhibitor in vitro. Its clinical effects
are unknown.

Epimedium alpinum flower; note the
spurs almost as long as the sepals
Labelled flowers ofE. × perralchicum 'Fröhnleiten'
Species
of Epimedium are herbaceous perennials, growing from an
underground rhizome. Their growth habits are
somewhat variable. Some have solitary stems, others have a "tufted"
habit, with multiple stems growing close together. There may be several leaves
to a stem or the leaves may be solitary, produced from the base of the plant.
Individual leaves are generally compound, often with three leaflets, but also
with more. Leaflets usually have spiny margins. The leaves may be annual,
making the plant deciduous, or longer lasting, so
that the plant is evergreen. The inflorescence is an open raceme orpanicle, the number of flowers
varying by species.[3]
Individual
flowers have parts in fours. There are four smaller outer sepals, usually greenish and
shed when the flower opens. Moving inwards, these are followed by four larger
petal-like inner sepals, often brightly coloured. Inside the sepals are four
true petals. These may be small and
flat, but often have a complex shape including a nectar-producing
"spur" that may be longer than the sepals. There are four stamens.[3]
One
of the common names for the genus, bishop's hat, arises from the shape of the
flowers, particularly where the spurs are longer than the sepals.[citation needed]
The
genus was given its name by Carl Linnaeus in 1753, along with
the European species E. alpinum.[1][4] The name is derived
from a Greek word for a different plant, epimedion. The meaning of
the original name is unclear.[5]

Some
varieties and hybrids have been in
western cultivation for the last 100 to 150 years. There
is now a wide array of new Chinese species being cultivated in the west, many
of which have only recently been discovered, and some of which have yet to be
named. There are also many older Japanese hybrids and forms, extending the
boundaries of the genus in cultivation. Few genera of plants have seen such a
dramatic increase in newly discovered species, primarily thanks to the work of
Mikinori Ogisu of Japan and Darrell Probst of Massachusetts. The majority of
the Chinese species have not been fully tested for hardiness nor indeed for any other aspect of
their culture. The initial assumption that the plants would only thrive where
their native conditions could be closely replicated have proven to be overly
cautious, as most varieties are proving extraordinarily amenable to general
garden and container cultivation.
While
they can be successfully propagated in early spring,
epimediums are best divided in late summer, with
the aim of promoting rapid re-growth of roots and shoots before the onset of
winter. Several breeders (in particular
Darrell Probst, Tim Branney & Robin White) have also undertaken their own
hybridization programmes with the genus. Various newnursery selections are
gradually appearing in the horticulture trade, the best of which are extending
the colour and shape range of the flowers available to the gardener.
Hugely
popular as garden plants for centuries in Japan, epimediums are only just
beginning to garner attention in the West. While they vary somewhat in their
respective hardiness, all are essentially dwellers of the forest floor, and, as
such, all require fundamentally similar conditions of moist,
free-draining, humus-rich soil and cool
shade, with some shelter for the newly emerging leaves. Some of the more robust
varieties are often recommended as plants for dry shade, and whilst their tough
foliage and stout rhizomes can allow them to
grow successfully in such conditions, (and in more open, exposed positions too,
in some instances) they will certainly not give their best. Furthermore,
dryness and exposure will pretty much guarantee the early death of many of the
newer and more delicate species.
Given
suitable conditions most epimediums will form beautiful groundcover plants, often with
magnificent new leaves tinted in bronze, copper and reds combining with a huge
variety of flower colours and forms in spring. Handsome and dense-growing
foliage remains present for much of the year, with the leaves often turning
purple, crimson and scarlet in autumn in some forms, and remaining evergreen in
others. With all varieties, however, the foliage is best cut off at ground
level shortly before new leaves emerge, so as to fully reveal their beauty of
form and colour. Ideally, a mulch should then be applied to protect the new
growth from frosts.

is sold as a health supplement, usually in raw herb, tablet, or capsule form
and sometimes blended with other supplements. The over-exploitation of wild
populations of Epimedium for use in traditional Chinese
medicine is having potentially serious consequences for the long-term survival
of several species, none of which is widely cultivated for medicinal purposes.[citation needed]
Icariin
is purported to work by increasing levels of nitric oxide, which relax smooth muscle. It has been
demonstrated to relax rabbit penile tissue by nitric oxide and PDE-5 activity.[8] Other research has
demonstrated that injections of Epimedium extract directly into the penis of
the rat results in an increase in penile blood pressure.[9]
Like sildenafil (the erectile
dysfunction drug commonly sold as Viagra), icariin, the active
compound in epimedium, inhibits the activity of PDE-5. In vitro assays
have demonstrated that icariin weakly inhibits PDE-5 with an IC50 of around 1 μM,[10][11] while sildenafil
has an IC50 of about 6.6 nM
(.0066 μM) and vardenafil (Levitra)
has an IC50 of about 0.7 nM
(.0007 μM).[12] Measured
differently, the EC50 of icariin is
approximately 4.62 μM, while sildenafil's is .42 μM.[13] With the weak
potency of epimedium, and its unknown oral bioavailability, whether orally
administered epidemium extract has any effect is unclear from the literature.
A
published Italian study modified icariin structurally and investigated a number
of derivatives.[14] Inhibitory
concentrations for PDE-5 close to sildenafil could be reached. Moreover, the
most potent PDE-5 inhibitor of this series was also found to be a less potent
inhibitor of phosphodiesterase-6 (PDE-6) and cyclic adenosine
monophosphate-phosphodiesterase (cAMP-PDE), thus showing it to have more
specificity for PDE-5 than sildenafil.
Epimedium
has been shown to up-regulate genes associated with nitric oxide production and
changes in adenosine/guanine monophosphate balance in ways that other PDE5
inhibitors do not.
Epimedium
was used in a patent infringement case to rescind
parts of the U.S. Viagra patent based on historic use in Chinese medicine. The
specific claim was that Viagra was the first medical example of a PDE5
inhibitor which treated erectile dysfunction and therefore claimed patent
protection from all similar PDE5 inhibitors. Patent examiners used epimedium as
an example of prior
use and
rescinded those portions of the patent, however, the Viagra patent still
protects the manufacturing process or chemical formula for sildenafil.[15]
Animal,
human, and in vitro studies indicate that icariin also
stimulates osteoblast activity in bone
tissue.[16][17][18][19][20][21]
Epimedium wushanense contains a number
of flavanoids. 37 compounds were characterized from the underground and aerial
parts of the plant. Among them, 28 compounds were prenylflavonoids. The predominant flavonoid, epimedin C,[22]ranged from 1.4 to 5.1%
in aerial parts and 1.0 to 2.8% in underground parts.[23]
