Why You’ll Love This Remedy

I love having comfrey growing in my fruit tree guild because it has a very large taproot, which draws up minerals from deep within the soil, making them available to the fruit tree. It additionally provides me with a simple remedy that can be made in just minutes. A comfrey poultice is:

• Natural - A practical way to put your medicinal herb garden to use.
• Simple - Easy to make with fresh or dried comfrey.
• Frugal - Budget-friendly and made from simple ingredients.
• Time-Tested - A traditional herbal remedy used for generations.

What Is Comfrey?

Comfrey (Symphytum officinale) is a perennial herb that has been used for centuries in traditional herbal practices. Often called "knitbone," comfrey earned its nickname because of its historical use for supporting recovery from bruises, sprains, and minor injuries.

The leaves contain allantoin, a naturally occurring compound that encourages healthy cell growth and tissue regeneration. This is why comfrey remains one of the most popular herbs among herbalists and homesteaders.

Beyond making a comfrey poultice, the plant is also commonly used in salves, infused oils, compost activators, and garden fertilizers. It is one of the most useful multi-purpose herbs you can grow in a homestead garden.

Key Supplies and Ingredients:

A full ingredients list, including measurements, can be found in the recipe card below.

• Comfrey - Fresh comfrey leaves are preferred, but dried comfrey leaves work, too.

• Blender - If you don’t have a high-powered blender, you can use a mortar and pestle, food processor, or simply a sharp knife.
• Gauze - Cheesecloth could also work in a pinch.
• Bandage or Wrap - Optional to secure the poultice.
• Food Scale - Comfrey is best measured by weight instead of volume.

How to Make a Comfrey Poultice:

Step 1: Take the comfrey flowers, leaves, and stems and place them into a high-powered blender. Add water and add the lid, and blend until you're left with a rough puree. (If using dried comfrey, place dried comfrey leaves in a small bowl, add warm water gradually until the leaves soften, and allow the mixture to sit for several minutes before placing it in the blender for the next step.)

Step 2: Add binder (I used flour) and blend again. Check consistency and add more binder, as needed, until you reach a paste consistency (similar to a muffin or cake batter consistency).

Step 3: Separate a large piece of gauze into two pieces. On the gauze with the wider weave, spoon on the comfrey poultice. How much you use and how wide you spread it out will be determined based on the injury.

Step 4: Cover the poultice with the tight-weaved gauze. This is simply to keep the poultice from running off the gauze. You can freeze the gauze to create a healing ice pack (see tips below for directions) or use it immediately.

Tips

• Grow Your Own Comfrey - Comfrey is one of the easiest medicinal herbs to grow. Once established, it returns year after year and produces abundant leaves throughout the growing season.
• Harvest Before Flowering - Leaves harvested before flowering are often considered ideal for medicinal preparations because they are tender and vigorous. To make sure you are getting the most from your medicinal herbs, read how to harvest herbs for medicinal purposes.
• Freeze for Future Use - Fresh comfrey leaves can be frozen and thawed later for making poultices when needed. Or, prepare your poultice, place it in an airtight container, and freeze for up to 12 months. This way, it's ready whenever needed.
• Keep Dried Leaves on Hand - Dried comfrey stores well and allows you to make a comfrey poultice year-round, even when fresh plants aren't available. Before drying comfrey, check out the best methods for drying herbs. 
• Test Sensitive Skin - If you have sensitive skin, test a small area first before applying the poultice more broadly.

How to Use a Comfrey Poultice

Once prepared, place the comfrey poultice over the affected area and leave it in place for approximately 20 to 60 minutes.

Traditionally, a comfrey poultice has been used for:

• Bruises
• Sprains
• Strains
• Sore muscles
• Minor swelling
• Achy joints
• Minor skin irritations

Many herbalists apply the poultice once or twice daily as needed.

Important Safety Note: Comfrey is generally recommended for external use only. Do not apply a comfrey poultice to deep wounds, puncture wounds, infected skin, or broken skin without guidance from a qualified healthcare professional. Because comfrey may encourage the skin's surface to heal quickly, it is best reserved for appropriate external applications.
