In some magical traditions, the use of blood is a powerful tool indeed. Despite the dramatic effects you'll see in movies and on television, most witches use blood magic only rarely, and for very specific purposes. It's not something that's undertaken on a whim, but with proper safety precautions, blood magic can be a mighty boost to spellwork.

Key Takeaways: Blood Magic

  • Blood magic doesn't have to be gory or messy, and it's not illegal.
  • In most forms of witchcraft, blood magic is seen as a very powerful experience, not to be taken lightly.
  • If you decide to practice blood magic, do so safely, with proper precautions.

Why Use Blood in Magic?

Why would blood be used in magic spells? Think about this for a minute: blood is associated not only with death, but with life. It's a symbol of both pain and love. Taking blood can destroy a life, but giving it can save one. Blood is one of the ultimate magical paradoxes, and its use doesn't have to be scary or malevolent. Blood magic doesn't necessarily mean animal sacrifice, nor does it mean illegal activities taking place with some weird cult in the shadows. In other words, blood magic is really no big deal, and if done correctly, it doesn't even have to be messy or gory.

Cultures around the world have included blood, semen, and urine in magical practices for ages, and it's found in a variety of magical traditions throughout history. Blood magic is simply the use of a few drops of your own blood to create a magical bond between yourself and the spell. Most experienced practitioners agree that blood magic isn't for beginners—because there are plenty of other things you can use for magical links before you get to the powerful use of your own blood. Try doing work with hair, nail clippings, or saliva before you move on to blood.

Blood Magic Safety

If you're going to include blood magic as part of your spellwork, it's crucial to do so safely. Keep in mind that a little bit goes a long way, so don't ever use more than a few drops of your blood. Sanitize the area thoroughly before you poke any holes in your skin; a sterilized needle or the tiny lancets used by diabetics to check blood sugar is all you'll need. Squeeze out a couple of drops, then immediately put a bandage on your skin. Universal precautions are important.

Although in some magical traditions, it's believed that allowing someone to consume your blood gives you control over the person, others feel that it's just the opposite—them consuming your blood gives them power over you. Regardless, there are safety issues at play here; in addition to bloodborne pathogens, consumption of blood can actually be toxic.

In addition, never take it from anyone incapable of giving or unwilling to consent. This includes those who are unconscious or asleep, children, and animals.

Types of Spells

There are different ways you can use blood in magic, and none of it has to be harmful. Consider using it in protection magic, healing spells, and even fertility magic. Incorporate it into your regular magical workings. Some women opt to use menstrual blood rather than pricking the finger; if you do this, use a menstrual cup to collect what you need for a spell.

Candle Magic

To do a simple protection spell with blood magic, you can do a bit of candle magic and add blood to give it a boost. Use a black candle for this spell. Combine a few drops of your blood with a base oil, and anoint the candle thoroughly in the mixture. Roll the candle in your choice of protective herbs, dried and powdered. Light the candle and let it burn all the way down—as the wax burns, along with the oils, herbs, and your blood, you'll build powerful protective energy.

Talismans, Amulets, and Charm Bags

If you've got some healing magic to do, crafting a talisman, amulet, or charm bag is a great approach. You can anoint a magical talisman or amulet with a drop or two of your blood, and once it's dried, keep it in your pocket or on a cord around your neck. If you're creating a healing bag, once you've filled it with herbs, stones, and other items, add a few drops of your own blood, and then seal it shut.


In some magical traditions, petitions or requests are written on paper and sent to the spirits or the gods. If you want to bring fertility, prosperity, or abundance your way, write a petition to the deities or spirits of your practice. Once it's written down, sign it by placing a dot of blood, with your fingertip, on the paper. The petition can then be rolled up, placed under a candle, or sent out to the universe in the normal manner of your belief system.

Divination Tools

Some people anoint their magical and divinatory tools—rune stones, Tarot cards, athames, or wands—with their blood to create a more powerful magical link between themselves and the tools. You don't have to do this, but if you do, make sure you only use a drop or two.
