Horny goat weed (Epimedium) contains an active flavonol known as icariin which is know to be responsible for the sexual healing properties of this herb. The science behind icariin in terms of how it works boils down to two different beneficial properties that icariin exerts on the body. These are anti-erectile dysfunction properties and enhancing testosterone levels. So let's take a closer look at these.
Two Properties of Icariin that Promote Sexual Health
- Nitric oxide – a major health benefit of icariin is found in its ability to boost nitric oxide levels. Nitric oxide is a chemical messenger that has the ability to cause blood vessels to relax. In so doing, more blood can circulate through a given organ or tissue and in this case the penis. This allows the penis to become engorged with blood such that erection can occur. So, icariin has the ability to rejuvenate the transmission of nitric oxide signaling when you take this herbal supplement which results in improved blood circulation around the body and notably to the penal tissues when a male is sexually aroused.
- Testosterone – Icariin increases free-circulating testosterone in blood which improves overall testosterone delivery to tissues. So, how does this explain boosted levels of libido or sexual drive? Testosterone is the primary male sex hormone that contributes to all parts of the sexual behaviors. Testosterone is not only important for the production of sperm but also controls libido.
Since the flavonol icariin can boost nitric oxide levels and increase free-circulating testosterone, it can vastly improve erectile dysfunction and increase sex drive on a mental and physical level. In that regard, this herbal supplement has a reputation as being an all in one male enhance supplement. Moreover, HGW is good for men of all ages whether you're 20 years old or 75.
How to Take Horny Goat Weed?
Horny goat weed dosages have been determined from rat experiments. They have been reported at 200mg per kg weight of a 40 percent icariin extract (80mg per kg animal weight). This has been determined by a weight conversion from rats to humans. So, this gives an estimate of what the human dose ought to be.
- 150 pound person: 900 mg icariin
- 200 pound person: 1,200 mg icariin
- 250 pound person: 1,500 mg icariin
Experiments that used a lower dose of icariin (1-10 mg per kg weight) are equivalent to: 15 to 150 mg icariin (200 pound person) and 18 to 180 mg icariin (250 pound person). Also know that a study on post-menopausal women and osteoporosis reported that a 60 mg icariin daily dose was active. This also correlates with the dosages which demonstrated positive effects in rats.
If you stay in these ranges, there should be no problem for overdosing. But, just in case it is good to know what the overdose symptoms are. Generally what you would see is nausea.
