What Is Horny Goat Weed?
Horny Goat Weed, also known as Epimedii Herba or Yin Yang Huo, is a Chinese herb belonging to the Epimedium genus. It contains substances that can enhance flow and improve sexual function. Additionally, this herb is used to support the treatment of various conditions such as cardiovascular disease, erectile dysfunction, osteoporosis, and arthritis [1], [2].
How Does Horny Goat Weed Work?
The primary active component of Horny Goat Weed is Icariin. This flavonoid plays a crucial role in providing health benefits.
For cardiovascular disease, Icariin may support treatment through its antioxidant and lipid-regulating effects [1]. Studies also suggest that Icariin protects endothelial cells by stimulating NO production. This effect can contribute to cardiovascular protection [3].
For erectile dysfunction, Icariin inhibits PDE5 and nourishes nerves. PDE5 is the "enemy" of erection; it breaks down cGMP, a critical substance in circulation to the penis, affecting the maintenance of erection hardness. By inhibiting PDE5, Horny Goat Weed helps cGMP function more effectively, thereby prolonging and enhancing erection hardness [4].
Moreover, NO also plays a crucial role in relaxing smooth muscles, increasing circulation to the penis, aiding in longer-lasting sexual intercourse. Enhanced NO production significantly contributes to improving sexual function [5].
5 Benefits Of Horny Goat Weed For Health
May Increase Testosterone
Icariin in Horny Goat Weed may increase testosterone levels in the blood. Furthermore, it has been shown to improve male reproductive organs, including the testes and penis [6].
A study involving male mice exposed to DEHP followed by Icariin supplementation showed that DEHP exposure reduced sperm count and exhibited signs of disrupted seminiferous tubules. However, these effects were reversed after the Icariin administration. The study suggests that Icariin protects mouse testes from DEHP damage by reducing ROS accumulation and promoting testosterone production [7].
May Increase Blood Flow
Horny Goat Weed may contain substances that enhance circulation function and improve sexual function [2].
Research has demonstrated that Icariin can improve erectile function in spontaneously hypertensive rats by reducing endothelial microparticles in the blood and inhibiting platelet activity [8]. Healthy endothelium is crucial in regulating blood circulation and reducing blood clot formation.
A study on rabbit models showed that Icariin relaxes smooth muscles in the cavernous body of the penis, increasing flow to the penis, helping men maintain harder erections, and improving sexual life [9].
Improve Sexual Function
Horny Goat Weed can enhance sexual function by inhibiting PDE5, nourishing nerves, and increasing nitric acid production. Inhibiting PDE5 speeds up flow to the penis, potentially prolonging erection duration during intercourse [4].
It is also used to reduce erectile dysfunction [2]. Research shows that Icariin can stimulate nerves related to sexual function [9].
A study combining Horny Goat Weed with four other herbs showed enhanced sexual behavior in male mice. This opens potential applications of Horny Goat Weed combined with other herbs in supporting male sexual dysfunction.
Improve Bone Health
Icariin may be significant in maintaining bone health and supporting osteoporosis [9]. Icariin can regulate several signaling pathways related to:
- Bone formation (osteogenesis)
- Inhibiting bone resorption (anti-osteoclastogenesis)
- Cartilage formation (chondrogenesis)
- Blood vessel formation (angiogenesis)
- Antioxidant effects
In another study, Icariin stimulated bone marrow stem cells (BMSCs) to transform into bone-forming cells (osteoblasts). Moreover, this study also demonstrated Icariin's effectiveness in reducing postmenopausal osteoporosis with minimal side effects [10].
Icariin can substitute or support the effects of bone morphogenetic proteins (BMPs) commonly used in bone regeneration. BMPs are costly and may cause side effects, making Icariin a promising alternative [11].
May Improve Postmenopausal Symptoms
Common mood disorders in pre-menopausal women can lead to despondency and adversely affect health. Icariin has been shown to improve depressive symptoms around menopause [12].
Furthermore, this activity of Horny Goat Weed may also help regulate disrupted sex hormones, balancing endocrine function [12].
Icariin can also increase neurotransmitters serotonin (5-HT), dopamine (DA), and noradrenaline (NA) in the brain, improving brain function [12].
Enhanced immune activity also helps women alleviate symptoms after menopause [12].
Another benefit of Horny Goat Weed for postmenopausal women is its effective treatment of postmenopausal osteoporosis [10].

Furthermore, it is advisable to avoid using Horny Goat Weed during pregnancy as it may harm the fetus. Nursing mothers should also refrain from using it. Individuals with bleeding disorders should avoid it as Horny Goat Weed may slow blood clotting, increasing the risk of bleeding and exacerbating bleeding disorders. Due to its estrogen-like effects, it may elevate estrogen levels and exacerbate hormone-sensitive conditions such as breast and uterine cancer. Before surgery, discontinue Horny Goat Weed use at least two weeks before reducing the risk of bleeding [2].
