Ginseng, often referred to as the “King of all herbs,” has a long and storied history in traditional Chinese medicine, where it has been used for centuries to treat various ailments and promote overall well-being 1. One of its reputed benefits is enhancing sexual function, particularly in men. While ginseng is often touted as a natural aphrodisiac, scientific exploration into its effects is ongoing. This article delves into the research on ginseng's impact on sexual function, exploring the compounds responsible, their mechanisms of action, potential side effects, and recommended dosages.

Ginseng and Sexual Function: What Does the Research Say?
Studies on the effects of ginseng on sexual function have yielded a mixed bag of results. Some research suggests that ginseng may positively impact erectile function, libido, and even sperm quality 1. For instance, a 2018 meta-analysis of 28 studies on herbs found Panax ginseng to be particularly effective for treating erectile dysfunction in men 3. A study published in the Journal of Urology reported that 60% of men with erectile dysfunction who were administered Korean red ginseng said it improved their ability to gain an erection 4. Another study indicated that Korean red ginseng may improve sexual function in menopausal women 3. Interestingly, ginseng may also play a role in fertility, as it has been shown to help preserve ejaculated sperm 1. This finding could have implications for fertility treatments.
However, it's important to note that other studies have shown less promising results. A 2021 review that analyzed nine studies involving 587 men with mild to moderate erectile dysfunction concluded that ginseng had a “trivial effect” on erectile function and no significant benefits for sexual desire or arousal 5. While some studies show promising results, others show minimal effects, highlighting the need for more research to fully understand ginseng's impact on sexual health.
It's worth mentioning that ginseng's effects on sexual function are not limited to humans. Studies have shown that ginseng can increase sperm counts in rabbits and even egg laying among hens 6. While this may seem like a curious aside, it illustrates ginseng's broader effects on reproductive function across different species.
Types of Ginseng
While Panax ginseng is the most commonly studied type, other varieties, such as American ginseng, also exist 6. American ginseng is believed to have similar effects on sexual function, potentially through the same mechanisms of action as Panax ginseng. However, more research is needed to directly compare the effects of different ginseng types on sexual health.
The Active Compounds: Ginsenosides
The potential sexual benefits of ginseng are primarily attributed to its active compounds called ginsenosides 2. These compounds are a class of steroid glycosides and triterpene saponins 7. Ginsenosides are believed to influence sexual function by promoting the production of nitric oxide (NO) in the blood vessels of the penis 8. NO is a crucial molecule for achieving and maintaining erections as it helps to relax the smooth muscles in the penis, allowing for increased blood flow 8.
Mechanisms of Action: How Ginseng Improves Sexual Function
Ginseng is believed to work through a combination of mechanisms to improve sexual function:
- Enhanced Blood Flow: By promoting nitric oxide production, ginseng may help to relax blood vessels in the penis, leading to increased blood flow and improved erectile function 8.
- Hormone Regulation: Ginseng may influence hormone levels, such as testosterone, which plays a vital role in male sexual function 1.
- Neurotransmitter Activity: Ginseng may affect neurotransmitter activity in the brain, potentially influencing libido and sexual arousal 2. However, more research is needed to confirm these effects.
- Antioxidant and Anti-Inflammatory Effects: Ginseng's antioxidant and anti-inflammatory properties may also contribute to its potential benefits for sexual health. By protecting against conditions that can impair sexual function, such as atherosclerosis, ginseng may indirectly support sexual well-being 8. It's also worth noting that ginseng may have a positive impact on cardiovascular health in general, which is closely linked to sexual function 8.
Potential Side Effects and Interactions
While ginseng is generally considered safe for most people, it's important to be aware of potential side effects and interactions. Some possible side effects include nervousness, insomnia, headaches, digestive problems, and changes in blood pressure and blood sugar 10. Some authorities recommend limiting ginseng use to 3 months due to the possible development of side effects 11.
Ginseng may also interact with certain medications. For example, ginseng may decrease the effectiveness of warfarin (a blood thinner), increasing the risk of blood clots 13. It may also lower blood sugar levels, potentially leading to hypoglycemia when taken with diabetes medications 13. Additionally, ginseng may increase the risk of side effects when taken with MAOIs (monoamine oxidase inhibitors), a type of antidepressant 14.
To minimize the risk of side effects and ensure you're getting the most benefit, it's important to choose high-quality ginseng supplements.
Choosing High-Quality Ginseng Supplements
When choosing a ginseng supplement, it's crucial to select a high-quality product from a reputable source. Look for supplements that are standardized to contain a specific percentage of ginsenosides.
| Brand | Dosage | Form | Description |
|---|---|---|---|
| Auragin Korean Ginseng | Varies | Capsules | Standardized to contain 8% ginsenosides |
| Korea Ginseng Corp | Varies | Capsules, Extracts, etc. | Offers various ginseng products with different ginsenoside concentrations |
| NOW Foods Panax Ginseng | Varies | Capsules | Standardized to contain 2% ginsenosides |
Recommended Dosages
The recommended dosage of ginseng can vary depending on the form of ginseng, individual health status, and the specific condition being addressed. Most research studies suggest daily doses of 200 milligrams of Panax ginseng extract or 0.5-2 grams of dry root 15. When taken as a capsule, dosages typically range from 100-600 milligrams daily 15.
American ginseng has been studied at the following dosages:
- Adults: 200 to 400 mg by mouth twice daily for three to six months 16
- Children age 3 to 12: 4.5 to 26 milligrams per kilogram (mg/kg) by mouth daily for three days 16
It's always best to start with a lower dose and gradually increase it as needed, under the guidance of a healthcare professional.
Conclusion: Ginseng for Sexual Health
Ginseng, with its active compounds called ginsenosides, may offer potential benefits for sexual function, particularly in men. While research findings are mixed and more high-quality studies are needed, ginseng appears to improve erectile function by increasing nitric oxide production and enhancing blood flow to the penis 17. It may also influence hormone levels and neurotransmitter activity, although more research is needed to confirm these effects.
It's crucial to remember that ginseng is not a magic bullet for sexual dysfunction. Its effects can vary from person to person, and it's essential to be aware of potential side effects and interactions with other medications. If you're considering using ginseng to improve your sexual health, consult with a healthcare professional to determine if it's right for you and to discuss appropriate dosages and potential risks. They can help you weigh the potential benefits against the possible risks and make an informed decision about whether ginseng is a suitable option for your specific needs.
