Surrounding images depict pomegranates, red berries, grape juice and blueberries that can be used to create edible blood moulage. To the right, there are icons for freezing, microwaving, and squirting directly.
  1. Freeze fruits like cherries, berries, or pomegranates for a realistic red hue. When needed, microwave a few frozen berries to thaw partially. Bursting the skin releases a viscous liquid that resembles blood. 
  2. Cornstarch, coffee grounds, clear syrup, chocolate sauce, glycerine, honey, vegan gelatin (agar-agar powder) can be added for a thicker consistency, but they’re not essential. Remember, the ultimate goal of simulation is to practice skills, and not all scenarios require the exact viscosity and texture of real blood. Just as we suspend belief and treat plastic manikins as human bodies, fruit-based concoctions can represent blood. 
  3. Additionally, dark red juices like cranberry or grape can be stored in the refrigerator and squirted during simulations to mimic blood splatter. 

This ‘homemade moulage blood’ approach allows you to run effective skills labs on a budget, while keeping the learning process fun and safe for participants due to the edible and skin-safe ingredients.

Step Up Blood Moulage Realism

Here are 3 recipes that require blending of ingredients to achieve the viscosity, texture, color and smell of blood.

  1. Blend liquid starch, red food color, blue food color, yellow food color and chocolate syrup in a bowl.
  2. Mix clear dishwashing liquid with liquid starch and red food coloring.
  3. Use an electric blender to mix powdered sugar, cocoa powder and red food coloring to water. Steve Spangler demonstrates how to make fake blood with this recipe.

DIY Blood Moulage Ingredients: A Healthcare Simulation Specialist’s Guide

While well-funded simulation centers have access to top-of-the-line commercial blood moulage products, there’s a place for DIY options too! Here’s a breakdown of common DIY ingredients and how they contribute to blood simulation, along with tips from a simulation specialist’s perspective:


  • Effect: Thickens blood moulage, mimicking clot formation.
  • Do: Use sparingly to avoid an overly matte finish.
  • Don’t: Overmix, as it can create a paste-like consistency.
  • Substitute: Add finely ground oats for a slightly textured effect.

Coffee Grounds

  • Effect: Adds a realistic brown hue and slight grittiness, mimicking dried blood.
  • Do: Use finely ground coffee for a smoother texture.
  • Don’t: Go overboard, as it can overpower the red color.
  • Substitute: Ground cinnamon can offer a similar color variation.

Clear Syrup (Corn Syrup, Light Agave Nectar)

  • Effect: Provides a base viscosity and glossy sheen, similar to fresh blood.
  • Do: Experiment with different syrups to find the desired consistency.
  • Don’t: Use dark syrups, as they can alter the final color.
  • Substitute: Honey can be used in small quantities, but it’s slightly sticky.

Chocolate Syrup

  • Effect: Deepens the red color and adds a hint of brown, creating a richer blood tone.
  • Do: Use sparingly, as too much chocolate can make the mixture smell artificial.
  • Don’t: Rely solely on chocolate for color; combine it with red food coloring.
  • Substitute: Cocoa powder mixed with syrup can create a similar effect.


  • Effect: Creates a slightly slippery texture and a dewy finish, mimicking fresh blood.
  • Do: Add a few drops at a time to achieve a subtle sheen.
  • Don’t: Overuse, as it can make the mixture too slippery and compromise sticking properties.
  • Substitute: Vegetable oil can be used, but it doesn’t offer the same dewiness.


  • Effect: Adds a sticky consistency, mimicking thicker blood or dried blood residue.
  • Do: Use in minimal quantities due to its stickiness.
  • Don’t: Rely solely on honey for viscosity, as it can be difficult to clean up.
  • Substitute: A mixture of cornstarch and syrup can provide a similar sticky effect.

Vegan Gelatin (Agar-Agar Powder)

  • Effect: Creates a gel-like consistency, mimicking clot formation or thickened blood.
  • Do: Follow package instructions for proper preparation to avoid lumps.
  • Don’t: Make large quantities in advance, as gelatin has a limited shelf life.
  • Substitute: Xanthan gum can be used to create a thickening effect, but it won’t gel.

DIY edible blood moulage generally has a shorter shelf life than commercial products. Plan accordingly and dispose of expired mixtures.

Why Use DIY Edible Blood Moulage?

Blood Moulage For Specific Use Cases by Moulage Concepts

Moulage Concepts offers blood moulage products for specific use cases:

  • Fresh Blood: This product mimics the visual and physical properties of real blood, including setting, gelling, and drying realistically under varying temperatures. This makes it suitable for a wide range of training environments.
  • Slow-Flo Blood: This option provides a continuous flow of deep red simulated blood, ideal for scenarios involving active bleeding. Unlike real blood, it won’t dry out, eliminating the need for frequent replacements during training.
  • Invisible Blood: This water-activated powder is invisible on skin and clothing until water is applied. This allows for precise control over the timing and location of blood appearance in a training simulation.
  • Active Bleed Set: This two-part system facilitates the controlled application of simulated blood, enabling trainees to practice treating injuries caused by physical blows or knife wounds.
  • Simulated Blood Glucose: This product allows learners to practice blood sugar level testing during simulations, adding another layer of complexity and realism to medical scenarios.

Teaching Advanced Blood Moulage Effects

Techniques you can teach learners while having the kind of fun and engagement seen in an art class.

Blood Spatter

  • Toothbrush Technique: Use a stiff bristle toothbrush dipped in red paint or moulage to flick blood spatters onto your simulation. Vary the distance and pressure to create a realistic splatter pattern.
  • Straw Technique: For finer blood spatter, dip a straw in red paint or moulage and blow forcefully across the open end, creating a mist of tiny droplets.

Blood Blisters

  • Silicone Technique: Create a small pocket using Pros-Aide (a medical adhesive) on the skin. Fill the pocket with a clear gel and top it with red paint or moulage to create a raised blood blister.
  • Makeup Bead Technique: Apply a small amount of petroleum jelly to the skin. Place a red makeup bead on the desired location and carefully cover it with Pros-Aide to create a realistic dome-shaped blister.

Arterial Spray

  • Syringe Pump: Fill a syringe with red paint or moulage thinned with water. Attach the syringe to a small tube and secure it near the wound. Use a pump mechanism to create a pulsating effect, simulating arterial spray.
  • Compressed Air Can: For a simpler alternative, fill a compressed air can with red paint or moulage. Use a short burst to create a splatter effect resembling arterial spray.


  • Makeup Techniques: Apply layers of blue, purple, and red makeup to create a realistic bruise. Blend the edges for a natural look. You can also use bruise wheels specifically designed for makeup application.
  • Stippling with Sponges: Use a makeup sponge to dab on blue, purple, and red paints or moulage to create a bruised effect. This technique offers more control over the color variation.

When teaching advanced blood moulage effects, prioritize the safety of learners. Ensure materials are non-toxic and skin-safe. Petroleum jelly can be used as a barrier to protect the skin from adhesives.
