Scratches in Horses: Treatment Options That Actually Heal

Introduction

If you own a horse, you have likely dreaded finding those tell-tale scabs on the back of the pastern. Whether you call it Scratches, Mud Fever, Dew Poisoning, or Greasy Heel, the frustration is the same.

It often starts as a small irritation but can quickly spiral into swollen, painful legs that cause lameness. If you feel like you are stuck in a cycle of picking scabs, scrubbing legs, and seeing the infection return week after week, you aren't alone.

The problem isn't usually the horse—it's the treatment method. Here is the veterinary perspective on why Scratches is so stubborn and the 3-step protocol to actually cure it.

What is Scratches (Mud Fever) really?

Scratches is not a single disease; it is a cutaneous condition caused by a complex mix of bacteria and fungi that thrive in moist environments. When the skin barrier on your horse's leg is compromised—by mud, wet bedding, or constant washing—microbes enter the microscopic cracks.

Once inside, they create inflammation, heat, and those stubborn, crusty scabs.

The 3 Biggest Mistakes Owners Make

Before we talk about the cure, we need to stop the habits that make it worse. Most "traditional" advice actually damages the skin further.

• Mistake #1: Aggressive Scrubbing. Scrubbing raw skin with harsh chemicals destroys the healthy cells trying to heal the wound.
• Mistake #2: Picking Dry Scabs. This is painful for the horse and creates open wounds for new bacteria to enter. (We need to soften them first!)
• Mistake #3: Trapping Moisture. Using petroleum-based ointments (like diaper cream) over wet skin seals the bacteria inside, creating an incubator for infection.

The Protocol: How to Treat Scratches Effectively

To break the cycle, you need a medical-grade approach that cleanses without stripping and protects without trapping heat. Here is the Medica Veterinary Protocol.

Step 1: The "Reset" Cleanse (Day 1 Only)

You do not need to wash the leg every day. In fact, constant washing can keep the skin too wet and delay healing.

On Day 1 only, use a medicated wash to remove mud and debris. Our Rain Rot & Fungal Wash uses natural sulfur to eliminate the microbes driving the infection gently.

• For Daily Maintenance: Do not wash again. Simply use a dry cloth to wipe away yesterday’s salve residue before re-applying.

Step 2: The "Bone Dry" Rule

This is the most critical step. Bacteria love moisture. Before applying any treatment, ensure the leg is completely dry. Use a clean towel or even a hair dryer on a cool setting if your horse tolerates it.

Step 3: The Barrier That Heals

Once dry, applying a "stay-put" barrier is essential. This is where the Medica Healing Salve shines.

Developed by veterinarians, this salve does three jobs at once:

• It Protects (Zinc Oxide): Creates a physical, waterproof shield that locks out mud and morning dew.
• It Kills (Medical-Grade Sulfur): Continues to fight the infection underneath the barrier.
• It Soothes (Calendula & Vitamin E): Stops the itch instantly and softens the heavy crusts.

Why "The Barrier" Matters

The secret to the Medica Salve is its keratolytic effect. It naturally softens the hard, painful scabs so they slide off on their own when you wipe the leg the next day.

No picking required. The scabs will literally wipe off in your hand, leaving healthy skin underneath.

Unlike thin creams that slide off in the paddock, our salve stays in place, providing 24-hour protection so the skin can rebuild itself undisturbed.
