3. Icariin for Promoting Male Sex Performance
The first major sexual health benefit of Iariin is that it can increase Nitric Oxide production. A boost in Nitric Oxide is vitally important for healthy male erectile function because Nitric Oxide acts as a chemical transmitter to instruct the successful and plentiful delivery of blood to the penis tissue, hence if Nitric Oxide production becomes somewhat impaired then a male will experience a decrease of blood delivery to the penis which will lead to either a partially erection or a completely non-erect penis, even when sexually stimulated.
Iariin has the powerful function to rejuvenate the transmission of Nitric Oxide signalling when taken over an adequate space of time and this rejuvenation results in greatly promoted circulation within the body especially to the penis tissues.
Promoting the levels of free-circulating testosterone around the body improving overall testosterone delivery is the next benefit of consuming Horny Goat Weed extract containing various percentage of Iariin. Testosterone has long been regarded to be the primary male sex hormone contributing to the male sexual stimulation because testosterone hormones are critically responsible for such health aspects as strong sexual desire (sex drive) and also the healthy production of sperm.
Because of Iariin haveing the function of both a boost in transmission of Nitric Oxide and production of free-circulating testosterone, it not only vastly improves male erectile function but also increases the sex drive on a mental and physical level and above two key factors are precisely explain why Horny Goat Weed extractIariin gains such expansive reputation as a natural one-stop male enhancement supplement. Most importantly, such beneficial effects of icariin are prominent in men of all ages no matter you are at age of 20 or 60.
4. About Epimedium
Epimedium, also known as barrenwort, bishop’s hat, fairy wings, horny goat weed, rowdy lamb herb, randy beef grass or yin yang huo, is a genus of flowering plants in the family Berberidaceae.
Epimedium is a genus of about 60 flowering herbs, cultivated as a ground cover plant and an aphrodisiac. Many species are endemic to southern China, meaning they grow only there. Other species have a native habitat covering other parts of Asia and Europe. Epimedium plants have common names including bishop’s hat, horny goat weed, and yin yang huo.
Plants in the Epimedium genus are very adaptable and grow well in gardens and containers. There are many cultivated hybrids, and the plant’s popularity is growing in the West. In the wild, Epimedium grows on the forest floor, and the plants do best in similar environments, including moist, rich soil, cool shade, and shelter from strong winds.
The plants have long been used in Japan as a ground cover for their attractive foliage and flowers, which grow in a wide variety of colors. Most plants bloom in the early spring. The leaves of some species also change color in the fall, while other species retain their leaves year round.
Many species of Epimedium, particularly E. grandiflorum, are used as an aphrodisiac. The common name horny goat weed derives from a legend that the aphrodisiac properties of the plant were first noted by a Chinese goat farmer who noticed an increase in sexual activity in his flock after they ate the herb. The active ingredient in the herb is icariin, which is believed to work by increasing nitric oxide in the body, which leads to the relaxation of smooth muscle tissue, and consequently to increased blood flow to the penis. Unfortunately, the manufacture of horny goat weed supplements has led to over-exploitation of Epimedium populations, any many species are becoming endangered as a result. Instead of being cultivated for medicinal use, most Epimedium used in Traditional Chinese Medicine (TCM) or sold over the counter as a dietary supplement is harvested from the wild.
The herb may also be used to treat osteoporosis, fatigue, memory loss, heart or liver disease, and high blood pressure. Possible side effects include difficulty breathing, nosebleed, vomiting, and dry mouth or thirst. Such side effects are associated with long term or excessive use.
Pregnant women should avoid taking Epimedium. The herb may also have adverse interactions with medications used to treat high blood pressure and prevent clotting, so caution should be taken when combining these medications. It is always important to discuss any herbal supplements or over the counter drugs with one’s physician before taking them.
5. Scientific Support
Animal studies have shown that epimedium may function a bit like an adaptogen (such as cordyceps, rhodiola, ashwagandha, and ginseng) by increasing levels of epinephrine, norepinephrine, serotonin, and dopamine when they are low (an energy-promoting effect), but reducing cortisol levels when they are elevated (an anti-stress effect).
There is also evidence that epimedium can restore low levels of both testosterone and thyroid hormone (bringing low levels back to their normal levels) – which may account for some of the benefits of epimedium in improving libido (sex drive). Animal studies using epimedium have shown a reduction in bone breakdown, an increase in muscle mass, and a loss of body fat-each of which may be linked to the observed return of abnormal cortisol levels back to normal values (and rhythm).
In a series of studies conducted in humans and animals by Chinese researchers, immune-system function was directly suppressed and bone loss was accelerated, by using high-dose synthetic cortisol (glucocorticoid drugs). Subsequent administration of epimedium extract reduced blood levels of cortisol and improved immune immune-system function (in the humans) and slowed bone loss and strengthene.
