Blood Magic

‘Blood magic’ conjures up all kinds of gothic images, doesn’t it? The very word ‘blood’ is a real attention-grabber. Combine it with words like ‘magic’, ‘ritual’, ‘spell’, or ‘rite’ and the first thing that comes to mind is human sacrifices on a stone altar dripping with dark red and other images that look like something straight out of a horror movie.

As usual, the fiction is much darker and more stirring than the reality of it. Yes, blood can be dangerous— both magically and mundanely. But fire can also be dangerous, and yet no one would think to tell you not to use it to cook your meals. You just have to learn how to use it safely and properly.

The truth is that blood magic can be quite potent if you’re inclined to do it, and if you know what you’re doing. It should not be undertaken lightly, or carelessly; but it doesn’t deserve the ‘taboo’ stamp that many are quick to give it.

Using Blood in Magic and Spells


The Power of Blood

I’m sure I don’t need to tell you that blood is a powerful thing. This is something that is so embedded in us that we all understand it. Fear and awe of blood goes way back to our earliest human ancestors. The sight of that bright red fluid—whether it was coming from an enemy or friend, your prey or yourself—got immediate attention. Blood is associated with such powerful concepts that some people can’t stand the sight of it, and might faint away if presented with too much. Hemophobia is the fear of blood.

Blood is associated with death: the slain warriors on the field, the victim of violence, the hunter’s prey all lay bloody in their final state. Blood is also associated with life: it’s part of the cycle of fertility that perpetuates life. If you lost too much blood, you would grow weak and die. If your blood is tainted, you will wither.

Blood is associated with pain: you see it when you stumble and fall, have an accident, or fight. Blood is also associated with passion: when you love doing something, when you are good at it, it’s ‘in your blood’. Someone you love, particularly family members, are your ‘blood’. Blood connects you to things, or others. Even if you don’t know someone, you can empathize with them, your ‘heart bleeds for them’. Blood is passion, it’s connection, it’s raw emotion.

Blood is life. It courses through your body delivering oxygen and nutrients to every part of you. Blood is energy—when you push yourself, your heart pounds and your pulse races as your blood flows even faster. A woman bleeds during her menstrual cycle, she bleeds when her hymen breaks, there’s blood at childbirth. If you donate blood you might be saving someone’s life.

Whatever little microscopic bits are floating around in there contain the very essence for all that you are. A scientists can (illegally) clone you if they had just a drop of your blood. Your blood contains your DNA—a blueprint not just for you, but your complete ancestral line.

Something that contains this much power is naturally powerful in magic. Perhaps some would say it’s too powerful.

Blood Magic Is Not Blood Sacrifice


Blood Magic: No Harm Necessary

Blood magic is not magic that involves killing people or animals in ritual sacrifice. Let’s just make that clear. We’re not talking about laying some innocent creature out on an altar or in the center of a pentagram and killing it, or wounding it. This would be all kinds of wrong, not to mention illegal, and is not at all what I mean when I talk about blood magic.

Blood magic is the use of a few drops of blood during a spell or ritual—usually your own blood, but if you are casting for someone else you could use theirs (with caution and permission, of course). Those few drops can add power to a magical working in any number of ways.

What Do You Say?

Is Blood Magic Evil?

The first thing you need to learn about blood magic is that it’s not inherently evil. Blood isn’t evil, is it? Does it make you ‘evil’ or desire to do malicious deeds just because it’s currently inside your body? If not, why do you think it would it become ‘evil’ outside of your body? Some people mistakenly think that using blood in magic is ‘dark’ or somehow only associated with malevolent intentions. This is simply not true.

The negative connotations stem back to that fear of blood I spoke about earlier: fear of our own mortality, fear of power, etc., are the kind of driving factors behind a fear of blood. Indeed, if you are hemophobic, you might want to avoid blood altogether. It’s not for everyone.

But I come from a more objective perspective. I see blood—like any object or component you would use in magic—as simply a tool. It’s a very powerful tool, but a tool nonetheless. It’s neither benevolent nor malevolent in its own right. You could use it for any number of purposes, though like any other tool it’s not advised to use it for unethical purposes.

Going back to the fire analogy—I could use fire to burn down my neighbor’s home when they piss me off. I have access to fire, which can be a very powerful destructive choice if I choose. So what stops me? The fact that I am an ethical person who has no interest in hurting others. Just because I don’t want to hurt someone with fire doesn’t mean I shouldn’t use it. By the same logic, I don’t want to hurt someone with blood magic; just because I don’t want to cause harm with it doesn’t mean I shouldn’t feel free to utilize this powerful tool.

A good implement to have for blood magic is the prickers that diabetics use to test their blood sugar.

Practicing Safe Blood Magic

Before I begin discussing ways to use blood in magic, let’s discuss ways to use it safely. First, there are a few don’ts to keep in mind:

  • Don’t ever take more than a few drops.
  • Don’t ever take blood from an unwilling participant (this includes animals because they cannot give consent).
  • Do not smear your blood on people, let people smear blood on you, or try to exchange blood in any way; remember that many diseases can be transferred through blood.
  • Do not ever consume blood, either directly or by putting it into a drink; aside from the fact that you can catch diseases, blood itself is toxic to human beings. More than a couple of teaspoons can cause haemochromatosis and potentially do some serious organ damage.
  • Don’t let others drink your blood, either directly raw or by putting it into food or drinks; this is essentially giving your power over to that person, and not in a good way.
