Before we get into why it might not work for you, let’s discuss how Viagra actually works. Viagra is the brand name for the drug sildenafil, which is a PDE5 inhibitor. PDE5 is an enzyme that can make it difficult for your blood vessels and arteries to relax and dilate. This can reduce the amount of blood flow to various parts of the body, including the penis. PDE5 inhibitors reduce the amount of the PDE5 enzyme in your body to increase blood flow for your erections. Therefore, sildenafil and other PDE5 inhibitors address blood flow problems that may cause erectile dysfunction.

More so, ginger has active compounds like gingerol, shogaol, and zingiberene. Gingerol compounds have positive effects on blood vessels. A Japanese study found out that gingerol stimulated blood vessels contractions in mouse and rat tissue samples by regulating eicosanoids, a signaling molecule.
