Synopsis

Rating (out of 5): 3

Ginseng, particularly Panax ginseng (also known as Korean red ginseng), is used to support or treat erectile dysfunction (ED) and has both a strong tradition in herbal medicine and some degree of scientific validation. Several randomized controlled trials and meta-analyses have investigated the efficacy of ginseng for ED. The proposed mechanisms include the enhancement of nitric oxide synthesis, which promotes vasodilation and improves blood flow to the penis, and possible effects on libido and testosterone levels.

A 2008 systematic review in the British Journal of Clinical Pharmacology found that ginseng significantly improved erectile function compared to placebo, although the number of high-quality studies was limited and many had small sample sizes. More recent meta-analyses (e.g., from 2018 and 2021) have confirmed a modest but statistically significant effect of ginseng supplementation on erectile function. The active components, known as ginsenosides, are thought to contribute to these effects by modulating endothelial function and neurohormonal activity.

Despite promising results, the overall quality of evidence is moderate, with some studies showing benefit and others showing little to no effect. Side effects are generally mild, but quality, dosage, and standardization of ginseng products can vary widely. In summary, there is scientific support for ginseng’s use in ED, but more rigorous, large-scale clinical trials are needed to confirm its efficacy and establish standardized dosing guidelines.
