What is the fear of blood called?

Fear of blood is called Hemophobia. It's an intense or irrational fear of blood, wounds, and injuries. It's also called hematophobia. Having an aversion to blood or fear of blood is natural—in fact, horror movies often prey on our discomfort by showing large quantities of fake blood to inspire fear and unease in their audience. However, hemophobia causes much more than discomfort, and someone with this condition will experience anxiety/stress at the sight of blood.
