Pills for erectile dysfunction work in a multiple ways to improve erections by:

  • Increasing blood flow to the penis
  • Supporting nerve response
  • Lifting testosterone levels
  • Reducing stress levels
  • Boost sex drive

 
Erection drugs like Viagra and Cialis do just one thing – increase blood flow to the penis. They will not work if your sex drive is low – for example – or your testosterone levels are below par.
 
Herbal erectile treatments like Herbal Ignite contain a range of herbs that work on all aspects of sexual health to improve response in multiple ways.
