A vasodilator is a substance that stimulates blood flow by dilating the blood vessels. Sexual enhancement and specialty lubricant products often use vasodilators like yohimbe, ginseng and L-arginine to enhance sexual performance and sensation.

The efficacy of vasodilators varies considerably. Some vasodilators are potentially dangerous for people with inflammatory lung diseases, but because personal lubricant products work locally, negative side effects are typically rare. Please be aware that if you have a inflammatory disease such as Genital herpes, you should stay away from vasodilators as they can cause a outbreak.
