The main reason that causes erectile dysfunction is the lack of blood in the male sex organ.  Cnidium monnier contains a natural form of the compound 4-Methylpiperazine, which boosts the body’s ability to release nitric oxide and greatly increases the body’s ability to create cyclic Guanosine Monophosphate (cGMP) while inhibiting the production of Phosphodiesterase-V (PDE-5), an enzyme that breaks down cGMP and weakens a man’s erection.  cGMP is the key in obtaining and sustaining a powerful erection, it helps relax the muscles around the penis, allowing the penile arteries to expand and fill with blood.  This enhanced blood flow is vital to achieving and maintaining erections.
