A Natural Herb for Libido & Mood

A Natural Herb for Libido & Mood

The horny goat weed plant.

Horny goat weed is an incredible herb with a funny history. A Chinese goat herder noticed that animals who ate the plant’s leaves had an increased interest in sex.[1] This incredible herb doesn’t only work for goats!

A time-tested herbal supplement, horny goat weed is often used by men to boost sex drive and improve sexual performance. However, the aphrodisiac qualities of this herb apply equally to both males and females. Women have also started to use it, with great success.

What Is Horny Goat Weed?

Despite the silly name, horny goat weed (Epimedium grandiflorum) has held an esteemed place in traditional medicine for ages. It has a particularly long history in traditional Chinese medicine (TCM), where it’s called “yin yang huo” or Herba epimedii.

The main active ingredient in horny goat weed, icariin, is a flavonoid with strong antioxidant properties. Icariin also promotes a normal response to inflammation.[2, 3] People use horny goat weed for a variety of health issues, ranging from erectile dysfunction (ED) and low testosterone to supporting bone and heart health.

You can find horny goat weed in extract, tincture, capsule, or powder form. You can even take horny goat weed tea. While many people think of this herb for men, you can also use horny goat weed for women with excellent results.

Top Horny Goat Weed Benefits

Horny goat weed boosts libido and improve sexual performance, but its potential benefits don’t end there. Horny goat weed may also improve circulation, increase muscle strength, enhance bone health, and more.

Below are the top benefits that this herb — and its active ingredient icariin — provide.

1. Boosts Sex Drive

A healthy sex life can play an important role in overall quality of life. And in traditional medicine, horny goat weed is a common remedy for low libido.[4] The herb may balance hormone levels and stimulate blood flow — important factors in sex drive and sexual performance. It works in several ways, including the ones below.

Erectile Function

If you have trouble getting or keeping an erection, this can affect your sex life. Many people turn to horny goat weed in these situations. Icariin (the active ingredient in horny goat weed) boosts the production of nitric oxide in the penis, a substance that helps blood vessels dilate. As blood vessels dilate, it increases blood flow to the penis, resulting in an erection.[5]

For those who want to know more details, icariin halts the action of PDE5 — an enzyme that otherwise decreases blood supply to the penis.[6] This is the same biochemical action that enables the “little blue pill” to work!

Testosterone Levels

Icariin has a twofold effect. Not only does it mimic the effects of testosterone in the body, but it also directly boosts testosterone levels in the blood.[7]

Both men and women produce testosterone, which plays a role in sexual desire and improves libido for both sexes.[7, 8] Horny goat weed may also improve the condition of reproductive organs.

Healthy Circulation

Horny goat weed also supports blood flow throughout the body.[9] The more blood circulating in the body, the more blood gets delivered to the sexual organs. In men, greater blood circulation increases the strength of an erection. Blood flow also enhances sexual arousal in both men and women.[10]

In short, horny goat weed helps your cardiovascular system and boosts libido by enhancing blood flow throughout your body.

2. Adds Happiness to Your Day

Anxiety, stress, and depression can affect sex drive, and horny goat shows promise for promoting a positive mood. Horny goat weed may balance cortisol — a well-known “stress hormone.” Reducing your body’s exposure to cortisol naturally boosts mood.

Icariin also promotes normal levels of corticotropin-releasing factor (CRF), a chemical indicator of stress in the body.[11] Higher CRF correlates with feelings of fear and anxiety, so lowering its levels benefits your mental wellness.

Icariin also influences two other stress-related compounds, interleukin-6 (IL-6) and tumor-necrosis-factor alpha (TNF-alpha), part of the well-known hypothalamic-pituitary-adrenal (HPA) axis.[11]

3. Promotes Nerve Cell Growth

It appears horny goat weed works through both the neuroendocrine and immune systems. The icariin in horny goat weed acts like a “neurotrophin” — a molecule that helps with nerve cell growth and repair.[5]

Nerves that line the penis influence pleasure. By improving nerve growth, the theory is that horny goat weed will increase sexual enjoyment. And of course, healthy nerves are important not only for sexual enjoyment but also for your brain and entire nervous system.

4. Fortifies Your Bones

Looking for extra bone support? Horny goat weed holds promise as a natural and complementary therapy for people concerned about their bone health.[8]

Icariin stimulates new bone cells to form, improving bone density.[12, 13] As women go through menopause, they are at greater risk of bone loss and conditions like osteoporosis. Icariin appears to improve bone strength and reduce bone loss over time.[12, 13]

Horny goat weed’s support for a healthy skeletal system is particularly important in older individuals.[13]

5. Supports a Healthy Heart

Since horny goat weed supports circulation and new blood vessel formation, it is good for the heart. Horny goat weed’s heart-protecting effects come mainly from its antioxidant properties. Icariin can prevent cell death (apoptosis).[14, 15]

Icariin is also anti-inflammatory and, as mentioned, has antioxidant properties. If you have heart health risk factors, this herb can support your cardiovascular system.[16]

In addition to horny goat weed, you can find other vitamins and supplements to support a healthy heart. A healthy heart plays a vital role in a thriving sex life. Check out our article about healthy heart tips.

6. Reduces Fatigue

Who isn’t tired these days? With work, kids, daily stress, and more, most people consider low energy one of their biggest concerns. Good news: Horny goat weed may boost your vitality and help fight fatigue.

This power herb offers anti-fatigue and energy-boosting benefits, especially when used after exercise.[17] Icariin appears to decrease the build-up of lactic acid, which makes muscles tired and sore.[17]

Additional Health Benefits

Horny goat weed finds many more applications in traditional Eastern medicine. Healers may recommend the herb to:

  • Support healthy blood pressure
  • Reduce joint and back discomfort
  • Support kidney health
  • Boost liver health
  • Discourage memory loss & forgetfulness
  • Reduce nocturia (waking in the night to urinate)

Horny goat weed might even support female hormone balance during perimenopause and after menopause.[18]

Other Herbs for Libido

Horny goat weed is not the only herb that can enhance your sex drive. Multiple herbs are often combined in natural products to support libido and sexual function.[19, 20] These include the following popular libido herbs:


An exotic cooking herb, saffron is also an aphrodisiac in traditional medicine. Saffron may increase erection frequency, ability to reach orgasm, and arousal.[21]


More than just an ingredient for pumpkin pie, nutmeg may also bring spice to the bedroom. Nutmeg can increase sexual desire without side effects.[22]


Used in Unani medicine, also known as Arabian or Islamic medicine, clove has a positive impact on sexual activity.[23]


The flavonoids (antioxidant compounds) in passionflower may be responsible for their effect on sex drive.[24]

Maca Root

Maca powder may have a positive effect on sex drive in women, particularly postmenopausal women.[25]


The roots and fruits of Tribulus terrestris have aphrodisiac properties.[26] Tribulus may increase sexual behavior and promote testosterone production.[26]
