Herba epimedii (Epimedium, also called bishop's hat, horny goat weed or yin yang huo), a traditional Chinese medicine, has been widely used as a kidney tonic and antirheumatic medicine for thousands of years. It is a genus of about 60 flowering herbs, cultivated as a ground cover plant and an aphrodisiac. The bioactive components in herba epimedii are mainly prenylated flavonol glycosides, end-products of the flavonoid pathway. Epimedium species are also used as garden plants due to the colorful flowers and leaves. Most of them bloom in the early spring, and the leaves of some species change colors in the fall, while other species retain their leaves year round.

The herbs we used to extract icariin is one species of Epimedium, which name is Epimedium brevicornum Maxim. This kind of epimedium only can be abundantly found in Gansu province of China. And because of the growth habit of this kind of herb, which only grows under trees, it can’t to be planted, only can harvest the wild one.


This wild epimedium contains quite a bit of active components, depending on its long growth time and rich nutrient. Usually the content of the icariin is not lower than 1%.


Below photo is the herb specimen which we use. Picking in the epimedium full-bloom stage. And the medicinal value of the herb is the best at this time. The herb we select contains roots, stems, leaves and flowers. And we extract with the whole herb.

The plant extracts of epimedium traditionally used for male impotence, and the individual compounds is icariin, were screened against phosphodiesterase-5A1 (PDE5A1) activity. Human recombinant PDE5A1 was used as the enzyme source. The E. brevicornum extract and its active principle icariin were active. To improve its inhibitory activity, some derivatives ware subjected to various structural modifications, which include icaritin, icariside II and 3,7-bis(2-hydroxyethyl) icaritin. There have some scientific papers report that the improved pharmacodynamic profile and lack of cytotoxicity on human fibroblasts make such compounds a promising candidate for further development. We hope that our new products can help you to find more commercial opportunity.


In this way, we can introduce those products as below, and we can also provide more details about the products according to your demand. The 1H-NMR of icaritin and 3,7-bis(2-hydroxyethyl) icaritin is as below.
