Have you ever wondered what aspirin really does? 

Aspirin is one of the oldest drugs - yet we still know very little about how it functions. We know that aspirin blocks the synthesis of prostaglandins, which are lipid signaling molecules.

Aspirin has many effects:

    Relief of inflammation and pain

    Stomach irritation - bleeding ulcers

    Reversible female infertility

    Cancer prevention

    Heart disease prevention

It is unclear how aspirin causes these diverse effects, raising the question of what are the prostaglandins really doing?
