Stacking with Icariin? Read this before starting!

Icariin is a wonderful and fascinating compound with a whole lot of health benefits. You might be wondering where you can find herbs with Icariin. Interestingly, we can only extract usable amounts of Icariin from one plant genus, Epimedium.  Epimedium, also known as Barrenwort or Yin Yang Huo, is a plant genus that is found mostly in China and other parts of Asia, including Japan. Traditional Chinese medicine has used the Epimedium genus for over a thousand years. The most commonly used plant species for extracting Icariin is called Epimedium sagittatum.[1]

Supplement stacks: Mix with icariin

[caption id=""attachment_793"" align=""aligncenter"" width=""640""] Many supplement stacks combine herbs with icariin[/caption] One of the best things about Icariin is that it works so well on its own. However, some people enjoy mixing Icariin with Yohimbine. Yohimbine is another great vitality enhancer and aphrodisiac. The difference between Yohimbine and Icariin is that Yohimbine is also a powerful stimulant. So, please be careful when you mix these two supplements. Icariin, although safe and great by itself, can cause potentially dangerous side effects with some of the interactions it has.[2] A recent study found that Icariin may interact with a number of prescription medications, based on the way that it is absorbed in your stomach.[3] If you are taking any prescription medication, please consult your doctor before starting with an Icariin supplement. Importantly, many supplement stacks for boosting sexual health and for increasing energy before workouts contain Icariin with a number of other herb extracts. Surprisingly few people have reported side effects from these supplement stacks. However, we’d still recommend being on the safe side and avoid using icariin with other libido-enhancing herbs or stimulants.

A word of warning: Supplements with Icariin

As we mentioned above, there are a number of supplement stacks available that contain other ingredients with Icariin. These stacks have been shown in a few studies to have beneficial effects on vitality and libido.[5] However, the problem with stacks containing multiple herbal ingredients is the potential for dangerous interactions between the chemical compounds in each herb. Scientists have attempted to examine the potential effects of combination herbal formulas in a number of studies. However, this can be made difficult when supplements aren’t standardized.[6]   Also, supplement stacks tend to contain different ratios of herbs, making it difficult to create a safety profile for stacks in general. We recommend using a single ingredient extract for safety reasons. This is especially true for substances that haven’t yet had a lot of research done into their potential interactions, like Icariin.  


In conclusion, Icariin is a great herbal extract that can be used to improve vitality and libido. Icariin is still a relatively new dietary supplement in the West. Scientists are still studying many of the effects of Icariin, especially its interactions with prescription medication and other libido enhancing herbs.   We’d recommend a stack with Yohimbine and Icariin. Apart from that, Icariin is potent enough that you don’t need to combine it with other herbs. Simply read through user experiences online and you’ll see what we mean.
