Panax Ginseng
Korean red ginseng
What the evidence shows
Among the better-evidenced natural options for erectile dysfunction specifically — multiple RCTs and a meta-analysis support modest but real improvement in erectile function scores versus placebo, making it one of the few supplements on this list with genuine ED-specific trial support rather than just a plausible mechanism.
How it's thought to work
Ginsenosides appear to promote nitric oxide release in penile tissue and may have mild central nervous system effects on libido and arousal.
Typical Dosage
600–1000mg of standardized red ginseng extract, 2–3x/day.
Safety Notes
Can raise blood pressure and interact with blood thinners and diabetes medication. Not recommended alongside stimulants due to overlapping effects on heart rate.
