List of possibly effective herbs for erectile dysfunction
Here is a list of the herbs (“natural medicines”) with most evidence (see pubmed) for improving erectile dysfunction (ED):
Taking Panax ginseng orally seems to improve sexual function in men with ED.
Taking DHEA orally for 24 weeks seems to improve ED, orgasmic function, sexual desire, and overall sexual satisfaction in men with ED. DHEA seems to help men with ED secondary to hypertension or idiopathic ED, but doesn’t seem to improve ED related to diabetes or neurological disorders.
Taking L-arginine orally in high doses, 5 grams daily, seems to improve subjective assessment of sexual function in men with organic ED. But taking lower doses might not be effective. L-arginine 500 mg 3 times daily in men with mixed-type impotence doesn’t seem to be effective. There is also some preliminary clinical evidence that adding pycnogenol 40 mg 3 times daily might improve the effectiveness of low-dose (1.7 grams/day).
Preliminary clinical trials have shown melanotan-II used subcutaneously is superior to placebo in men with psychogenic or organic ED for initiating spontaneous sustained penile erections.
In men with diabetes and ED, combination therapy with propionyl-L-carnitine and sildenafil (Viagra) may improve erectile function better than sildenafil alone. In men unresponsive to 8 uses of sildenafil, adding propionyl-L-carnitine 2 grams daily to continued twice weekly doses of sildenafil 50 mg seems to improve erections and successful intercourse attempts more than treatment with sildenafil alone.
There is evidence suggesting that the primary constituent, yohimbine, can be helpful for impotence. Yohimbine seems to help men with organic, psychogenic, mixed, and unknown vascular ED. Some herbalists suggest that the yohimbe bark actually works better than the isolated yohimbine constituent; however, yohimbe bark has not been evaluated in studies.
Preliminary clinical research suggests pycnogenol, used alone or in combination with L-arginine, might improve sexual function in men with ED. It seems to take up to 3 months of treatment for significant improvement.
Preliminary research suggests that taking Butea superba might improve subjective measures of ED. However, poor study quality significantly limits the validity of these findings. More evidence is needed.
