How to Make an Herbal Compress
A compress is a cloth soaked in a strong herbal preparation and applied directly to a specific area of the body. It sits between a poultice and a bath in terms of directness: more targeted than a bath, less contact-intensive than a poultice, and especially suited to areas where you want sustained herbal contact and warmth (or coolness) held in one place over time.
Compresses have a quiet but solid place in traditional herbalism. They are one of those preparations that tends to be underused by beginners, perhaps because they sound more complicated than they are, but once you have made one, you realise how simple and immediately effective they can be.
Hot vs. Cold: Choosing the Right Approach
The most important decision with a compress is whether to use heat or cold, because they serve different purposes and should not be used interchangeably.
Hot compress: A cloth soaked in a warm herbal infusion or decoction, wrung out and applied as warm as is comfortable. As it cools, it is rewarmed and reapplied. Hot compresses are used to encourage circulation to an area, ease muscle tension, support relaxation of stiff joints, and draw out localised congestion.
Cold compress: A cloth soaked in a cooled or chilled herbal preparation, applied to bring down localised heat, reduce swelling, or soothe inflamed or irritated tissue. The classic cold chamomile compress held over tired or irritated eyes is one of the most well-known examples of this preparation in everyday use.
A general rule of thumb: use cold for acute inflammation, heat, or swelling; use heat for tension, stiffness, and poor circulation. When in doubt, cold is the safer starting point.
Step by Step: Making a Compress
What you need:
- A strong herbal infusion or decoction (use roughly double the amount of herb you would for a regular tea — you want a concentrated preparation)
- A clean cloth, flannel, or piece of muslin
- A bowl to hold the liquid
- Optionally: a dry cloth or towel to place over the top and hold in heat
Method:
- Make your herbal infusion or decoction and strain it thoroughly. You need a smooth, particle-free liquid.
- Allow it to reach the correct temperature for your intended compress: comfortably warm for a hot compress, fully cooled (or refrigerated) for a cold compress.
- Soak your cloth in the liquid. Wring it out well so it is saturated but not dripping.
- Apply to the area of the body you are working with.
- For a hot compress: lay a dry cloth over the top to hold in the warmth, and replace the compress when it cools to body temperature. Repeat for 15 to 20 minutes.
- For a cold compress: replace when it warms to body temperature. Apply for 15 to 20 minutes.
- After removing, pat the area dry and allow the skin to return to its natural temperature before redressing.
A compress can be used once or repeated two to three times daily, depending on the herb and the situation.
Herbs Commonly Used in Compresses
The herb you choose depends entirely on what you are working with and whether you are using heat or cold.
- Chamomile: one of the most widely used compress herbs, particularly as a cool compress for tired, irritated, or inflamed eyes, or for skin that needs soothing
- Arnica: traditionally associated with bruising and muscle soreness (important: arnica compresses should not be used on broken or abraded skin)
- Ginger: warming and stimulating; a hot ginger compress has a long tradition of use for joint stiffness, muscle tension, and areas of poor circulation
- Lavender: calming and aromatic; a cool lavender compress held to the forehead is a traditional approach to tension headaches
- St John's Wort: traditionally used for nerve-related discomfort and bruising, particularly where there is a radiating quality to the sensation
- Comfrey: long folk tradition for bruising and minor injuries (not on open wounds or broken skin)
- Rosemary: warming and stimulating; a hot rosemary compress for muscle tension and circulation
- Witch hazel: cooling and astringent; a compress-like application of witch hazel tea or extract has traditional use for varicose veins, bruising, and localised swelling
The Eye Compress: A Specific Case
The eye compress deserves its own mention because it is one of the most commonly made and most immediately useful compress preparations. A cool chamomile compress held gently over closed eyes for 10 to 15 minutes is a traditional remedy for tired, puffy, or irritated eyes.
To make one: brew a strong chamomile infusion, allow it to cool completely, soak two soft pads or folded pieces of clean muslin, lie back, and rest them over your closed eyes. The experience is, frankly, wonderful, and it requires no particular skill to make.
A Note on Safety
Do not apply a hot compress to acutely inflamed, red, hot, or swollen tissue — heat can worsen acute inflammation. When there is visible heat or redness, default to a cold compress first. Do not apply any compress to broken, infected, or open skin. Always make sure the temperature of a hot compress is comfortable before applying, and never leave a hot compress unattended on children or those with reduced skin sensitivity.
