Sildenafil, sold as Viagra (or generic brands), is a prescription drug used to treat erectile dysfunction. It works by promoting blood flow to the penis.
Although herbal remedies such as Horny Goat Weed, Yohimbe or red ginseng have been promoted for the treatment of erectile dysfunction, evidence of their effectiveness is absent or limited at best.
One study found the active ingredient in Horny Goat Weed, icariin, to be effective for treating erectile dysfunction in rats by inhibiting phosphodiesterase 5 – the enzyme that degrades an erection. Another study noted that icariin was a potent inhibitor of phosphodiesterase 5 and was not toxic to humans. However, potential side effects of Horny Goat Weed include dizziness, nosebleeds, and rapid heart rate.
Yohimbe is derived from the bark of the Pausinystalia johimbe tree. In a four-week trial, yohimbe was found to be safe and potentially effective for patients with mild to moderate erectile dysfunction. Whilst doses of 5 mg to 15 mg appear to be safe, overdoses can be fatal.
Ginseng is used for a wide range of conditions from cardiovascular disease to cold and flu. Ginseng may increase the release of endothelial nitric oxide which relaxes the smooth muscles of the penis leading to an erection. However, a review of multiple clinical trials for red ginseng was unable to conclusively confirm that the compound is effective in treating erectile dysfunction.
Herbal alternatives to Viagra may be effective for some men suffering from erectile dysfunction but additional studies are needed.
It’s worth remembering that Viagra can cause side effects as well. Potential side effects include; headaches, dizziness, muscle aches and visial disturbances. If you suffer certain from health conditions, you should not take herbal or pharmaceutical Viagra.
Speak to your doctor before taking any herbal ED remedies or pharmaceutical Viagra.
