What is Horny goat weed?
Horny goat weed (epimedium) has been used extensively in Traditional Chinese Medicine for more than three thousand years, as a yang-supporting herb for use by both men and women, which shows great therapeutic properties for the kidney, enhances the immune system, and increases sperm production, thereby acting sexual enhancement.

Horny Goat Weed is a herb (Epimedium) that is known for being an aphrodisiac and touted as a Testosterone Booster. It derives its layman names from goats and sheep who acted a bit more frisky after consuming Epimedium that grew near their fields.
It is also sometimes referred to by its active ingredient, Icariin. Icariin is known as a prenylated flavonoid compound and has been shown to exert much of the aphrodisiac effects of Horny Goat Weed. Icariin has not been shown to increase testosterone in females, yet two other compounds in Horny Goat Weed (Icaritin, Desmethylicaritin) have actually increased Estrogen in post-menopausal females. The herb acts as an aphrodisiac in both genders, and the gender-specific hormone increasing could be beneficial for both genders.

The story of horny goat weed
Though it has a humorous name, Horny Goat Weed is actually a hardy flowering plant that originated in China. The legend goes that a flock of goats was far more amorous than usual after grazing on the plant. It didn’t take long for someone to try it for themselves, and found that it worked on humans too! Called yin yan huo in China because of its medicinal qualities for both the female (yin) and the male (yang), Horny Goat Weed has been used as an aphrodisiac and sexual stimulant for centuries.

Chemical composition of Horny goat weed
Constituents of horny goat weed extract: One of the principal active ingredients in Horny Goats weed is “icariin”. The concentration may determine much of the potency of each particular species of Epimedium. However,there are many other ingredients in horny goat weed extract except icariin, such as flavones, Quercetin, Ikarioside A and B (wanshanense), Anhydroicaritin, Desmethylanhydroicaritin, Sagittatoside B , Diphylloside A and B, etc. Flavonoids are the main active chemical constituents of Epimedium species, the four major flavonoids contributing to their effects being epimedins A, B, and C, and icariin. These biologically active constituents are flavonol glycosides with an isoprenyl group substituted on carbon 8. However, analysis of natural health products currently available on the market containing Epimedium relys mostly on the presence of icariin.

Species of horny goat weed extract available
Horny goat weed, also known as epimedium extract, is unique to China. In other words, there are no horny goat weeds in other countries. Up to date, over 60 species of horny goat weeds have been reported, but only five of these are recorded in the Chinese Pharmacopeia, namely, Epimedium bravicornum Maxim., Epimedium sagittatum Maxim., Epimedium koreanum Nakai, Epimedium pubescens Maxim. and Epimedium wushanense T.S. Ying.

Icariins VS icariin
Most of the horny weed extracts are used in supplement formula in a standardized form of icariin. And many others use icariins instead of icariin. Many of our clients are supplement brands in both United States and the Europe, and they are confused with icariins and icariin. From the certificate of analysis (COA), you may also notice the difference by “assay Icariin(HPLC)” and “assay Icariins(HPLC)”. The superficial difference is the “S” behind icariin.
The method of analysis (known as MOA or testing method) for icariin and icariins is different.

The icariin is using acetonitrile as the mobile phase, while icariins using methanol (or aka methyl alcohol), and the reference standards for both testing are icariin. However, there are some problems with using methanol as the mobile phase. Great disturbance occurs during the icariins testing, and the errors always beyond the normal range. And there will be some extra things will come out of the testing.Two peaks of icariins are not separated,and thus the testing result is higher.Above all, the testing result for icariins is much higher than that of icariin. And that’s why companies in China are using acetonitrile as the universal mobile phase. (usually with the ratio of acetonitrile:water=25:75). The key differences between icariin and icariins are summarized as below:
1. icariin is popular and accurate, while icariins not. There are standard for icariin in ChinesePharmacopoeia, but no record for icariins. Icariin is identified with unique CAS number as 489-32-7, while icariins is a mixture of icariin and other uncertain ingredients, and no cas number is for icariins.
2. The price for the same percentage of icariin is higher than that of icariins. And the price of icariin is about 60% of the same specification of icariin. For example, the price of icariins 20% is only 60% of the price of the icariin. So don’t get fooled when you are buying icariins or icariin.

There are some cheats for icariins, so be careful with icariins. In addition, as we mentioned above, there are at least five other ingredient in horny goat weeds, and therefore there are five peaks from the HPLC spectrum.Some guys said icariin is the fifth peak, while icariins are peaks close to icariin.
