In the realm of herbal medicine, certain plants stand out as true wonders of nature, offering a wealth of healing properties that have been cherished for centuries. Among these botanical treasures lies comfrey, a perennial herb revered for its remarkable medicinal magic.
Understanding Comfrey’s Medicinal Magic
From ancient civilizations to modern herbalists, comfrey has earned a place of honor for its unparalleled ability to promote healing, soothe discomfort, and rejuvenate the body.
Allantoin – Nature’s Regenerator
Allantoin is a key compound found in comfrey, renowned for its remarkable ability to stimulate cell proliferation and promote tissue regeneration. When applied topically, allantoin accelerates the healing process by encouraging the growth of new skin cells, thereby aiding in the closure of wounds and promoting the repair of damaged tissue. This makes homemade comfrey salve an invaluable ally in the treatment of cuts, scrapes, and burns, as it facilitates faster healing with reduced scarring.
Rosmarinic Acid – Nature’s Anti-Inflammatory
Comfrey contains significant amounts of rosmarinic acid, a potent antioxidant with powerful anti-inflammatory properties. Rosmarinic acid helps to quell inflammation by inhibiting the production of pro-inflammatory enzymes and reducing oxidative stress within the body. By mitigating inflammation, homemade comfrey salve offers relief from a wide range of conditions, including arthritis, muscle strains, and joint pain, making it a natural alternative to conventional anti-inflammatory medications.
Tannins – Nature’s Astringent
Tannins, another class of compounds found in comfrey, possess astringent properties that help to tighten and tone the skin. When applied topically, tannins constrict blood vessels and reduce excess fluid accumulation, thereby diminishing swelling and promoting the rapid resolution of bruises and minor injuries. Additionally, the astringent action of tannins helps to soothe and protect irritated or inflamed skin, making homemade comfrey salve an effective remedy for conditions such as eczema, psoriasis, and dermatitis.
Mucilage – Nature’s Moisturizer
Comfrey contains mucilage, a gel-like substance that forms a protective barrier over the skin, sealing in moisture and preventing dehydration. This mucilaginous layer helps to soothe dry, rough, or damaged skin, providing relief from itching, irritation, and discomfort. By maintaining optimal hydration levels, homemade comfrey salve promotes skin health and resilience, leaving the skin soft, supple, and rejuvenated.
Alkaloids – Nature’s Analgesics
Comfrey contains alkaloids such as symphytine and echimidine, which possess mild analgesic properties that help to alleviate pain and discomfort. These alkaloids work by blocking pain signals and reducing nerve sensitivity, providing effective relief from sore muscles, joint stiffness, and other forms of musculoskeletal discomfort. By targeting the root cause of pain, comfrey salve offers long-lasting relief without the side effects associated with conventional pain medications.
The Versatile Applications of Homemade Comfrey Salve
Comfrey salve offers a wide range of versatile applications, from promoting wound healing and relieving muscle pain to managing skin conditions and reducing bruising and swelling. Its natural, plant-based formula makes it a safe and effective alternative to conventional skincare and pain relief products, providing holistic support for overall health and well-being.
Wound Healing and Skin Regeneration
Comfrey salve’s potent regenerative properties make it particularly effective in promoting wound healing and skin regeneration. When applied topically to cuts, scrapes, and minor burns, homemade comfrey salve accelerates the formation of new skin tissue, reduces inflammation, and minimizes scarring. Its ability to stimulate cell proliferation and collagen synthesis helps wounds heal faster and more efficiently, making it an invaluable addition to any first aid kit.
Muscle and Joint Pain Relief
Comfrey salve’s anti-inflammatory and analgesic properties make it a popular choice for relieving muscle and joint pain. Whether it’s sore muscles, arthritis, tendonitis, or sports injuries, applying homemade comfrey salve to the affected area can provide soothing relief by reducing inflammation, easing stiffness, and alleviating discomfort. Regular use of comfrey salve may also help improve mobility and flexibility, making it an essential remedy for individuals dealing with chronic pain or musculoskeletal conditions.
Skin Conditions Management
Comfrey salve’s soothing and moisturizing properties make it an effective remedy for managing various skin conditions. Conditions like eczema, psoriasis, dermatitis, and dry, irritated skin can benefit from the gentle, hydrating effects of homemade comfrey salve. Its anti-inflammatory and emollient properties help calm inflammation, relieve itching, and restore the skin’s natural barrier function, promoting overall skin health and resilience.
Bruise and Swelling Reduction
Homemade comfrey salve’s astringent and anti-inflammatory properties make it an excellent remedy for reducing bruising and swelling. When applied topically to bruised or swollen areas, comfrey salve helps constrict blood vessels, reduce fluid accumulation, and promote faster resolution of discoloration and swelling. This makes it a valuable addition to your skincare routine, particularly after minor injuries or surgical procedures, to minimize bruising and aid in the healing process.
Minor Skin Irritations and Insect Bites
Comfrey salve’s soothing and anti-inflammatory properties make it an effective remedy for alleviating minor skin irritations and insect bites. Whether it’s itching, redness, or swelling caused by mosquito bites, bee stings, or minor rashes, applying homemade comfrey salve to the affected area can provide instant relief and promote healing. Its gentle, natural formula makes it safe for use on sensitive skin, making it a versatile remedy for the whole family. However, comfrey should not be used on any deep cuts or lacerations (see contraindications below).
Fractures and Strains Of Bones
Comfrey may also be referred to as Knitbone due to it’s amazing ability to help speed the recovery, or “knit” the pieces, of fractures or strains in bones! It even contains this benefit in its botanical name, Symphytum officinale, Symphytum, means “to unite.” This ability is thanks to the allantoin in comfrey. This amazing compound is a cell proliferant, among others as mentioned above, which helps to regenerate wounded areas of the body and speed up new healthy cell growth.
Crafting Homemade Comfrey Salve
Having a homemade comfrey salve on hand is a great first-aid remedy to have on hand and crafting it is fairly simple!
Ingredients:
- Dried Comfrey Leaves (or Fresh Leaves): Comfrey leaves are the star ingredient of the salve, containing potent healing compounds such as allantoin, rosmarinic acid, and tannins. Dried leaves are commonly used in order to keep the water content low. If there is an excess of water, your salve may end up going rancid faster than you’d like.
- Carrier Oil: Carrier oils such as olive oil, almond oil, or coconut oil serve as the base for infusing the comfrey leaves. They help extract and preserve the beneficial compounds from the comfrey, creating a potent herbal infusion.
- Beeswax Pellets: Beeswax acts as a natural thickening agent and emulsifier, helping to solidify the salve and provide a smooth, creamy texture. It also forms a protective barrier on the skin, sealing in moisture and enhancing the salve’s healing properties.
- Optional: Essential Oils: Essential oils such as lavender, tea tree, or chamomile can be added for fragrance and additional therapeutic benefits. Check out some of our favorites down below!
Step-by-Step Directions:
- Infuse the Oil:
- Place the dried comfrey leaves in a clean, dry glass jar.
- Cover the leaves with the carrier oil, ensuring they are fully submerged.
- Seal the jar tightly and place it in a warm, sunny spot for 2-4 weeks to allow the comfrey to infuse into the oil. Alternatively, use a double boiler to gently heat the mixture for 4-6 hours, stirring occasionally, and maintaining a very low heat.
- Strain the Oil:
- After the infusion period, strain the infused oil through a fine mesh sieve or muslin cloth (I love using these bags for this process) into a clean container, ensuring all plant material is removed. Press the leaves to extract as much oil as possible.
- Melt the Beeswax:
- In a double boiler, melt the beeswax pellets over low heat until completely liquefied. Beeswax has a high melting point, so be patient and avoid overheating.
- Combine Ingredients:
- Once the beeswax is melted, gradually pour in the infused comfrey oil while stirring continuously to ensure thorough incorporation. Adjust the ratio of oil to beeswax based on your desired consistency – more oil will result in a softer salve, while more beeswax will yield a firmer texture.
- Add Optional Essential Oils:
- If desired, allow the mixture to cool until you’re able to touch it without burning yourself, then add a few drops of essential oils for fragrance and additional therapeutic benefits. Stir well to evenly distribute the essential oils throughout the salve mixture.
- Optional Whipping:
- If you prefer a smooth, whip consistency, use an immersion blender or hand mixer for a few minutes until nice and fluffy.
- Test the Consistency:
- To test the consistency of the salve, place a small amount on a spoon and allow it to cool. Adjust the thickness by adding more beeswax for a firmer salve or more oil for a softer consistency.
- Pour into Containers:
- Once you achieve the desired consistency, carefully pour the comfrey salve mixture into clean, airtight containers such as jars or tins. Allow the salve to cool and solidify completely before sealing the containers.
Homemade comfrey salve can store for over a year in an airtight container. The beeswax is a natural preservative so there’s no need to add anything else to increase shelf life!
Enhancing Comfrey Salve with Optional Essential Oils
While comfrey salve is potent and effective on its own, incorporating optional essential oils can elevate its therapeutic properties and add delightful fragrances. Essential oils are highly concentrated plant extracts known for their various health benefits, including anti-inflammatory, antimicrobial, and soothing properties. Here are several optional essential oils you can consider adding to your comfrey salve, along with the benefits they offer:
Lavender Essential Oil
Lavender essential oil is renowned for its calming and soothing properties. Adding lavender oil to homemade comfrey salve can enhance its relaxation benefits, making it an excellent choice for promoting stress relief and aiding in sleep. Lavender oil also has mild analgesic properties, which can complement comfrey salve’s pain-relieving effects, providing additional comfort for sore muscles and joints.
Tea Tree Essential Oil
Tea tree essential oil possesses powerful antimicrobial and antiseptic properties, making it an excellent addition to comfrey salve for wound care. Incorporating tea tree oil can help prevent infection and promote faster healing of cuts, scrapes, and minor burns. Additionally, tea tree oil has anti-inflammatory properties that can further reduce swelling and inflammation, enhancing the overall healing process.
Peppermint Essential Oil
Peppermint essential oil offers a refreshing and cooling sensation when applied topically. Adding peppermint oil to comfrey salve can provide relief from muscle tension, headaches, and minor aches and pains. Its invigorating aroma can also help uplift mood and increase alertness, making it an excellent choice for daytime use or as a pick-me-up after physical activity.
Eucalyptus Essential Oil
Eucalyptus essential oil is renowned for its respiratory benefits and soothing effects on sore muscles and joints. Incorporating eucalyptus oil into comfrey salve can help alleviate congestion, ease breathing, and provide relief from coughs and cold symptoms when applied topically to the chest or back. Eucalyptus oil also has analgesic properties that can enhance comfrey salve’s pain-relieving effects.
Chamomile Essential Oil
Chamomile essential oil is prized for its anti-inflammatory and calming properties. Adding chamomile oil to comfrey salve can soothe irritated or inflamed skin, making it an excellent choice for individuals with sensitive skin or inflammatory skin conditions like eczema or dermatitis. Chamomile oil’s gentle, floral aroma can also promote relaxation and stress relief, enhancing the overall healing experience.
Frankincense Essential Oil
Frankincense essential oil has been used for centuries for its anti-inflammatory and skin-rejuvenating properties. Incorporating frankincense oil into comfrey salve can promote cellular regeneration, reduce the appearance of scars and blemishes, and improve overall skin tone and texture. Its earthy, woody aroma can also promote a sense of grounding and tranquility during use.
When incorporating essential oils into your comfrey salve, it’s essential to dilute them properly to avoid skin irritation or sensitization. A general rule of thumb is to use no more than 1-2% essential oil concentration in your salve recipe, depending on the specific oil and individual sensitivity.
- 1% Essential Oil Concentration:
- To achieve a 1% concentration of essential oil in a 2-ounce comfrey salve recipe:
- 1% of 56.7 grams = 0.01 * 56.7 = 0.567 grams (approximately 11-14 drops)
- This means you would add approximately 0.567 grams of essential oil to the salve recipe.
- 2% Essential Oil Concentration:
- To achieve a 2% concentration of essential oil in a 2-ounce comfrey salve recipe:
- 2% of 56.7 grams = 0.02 * 56.7 = 1.134 grams (approximately 23-26 drops)
- This means you would add approximately 1.134 grams of essential oil to the salve recipe.
Always perform a patch test before widespread use, especially if you have sensitive skin or allergies. By carefully selecting and incorporating optional essential oils, you can customize your comfrey salve to suit your specific needs and preferences, enhancing its therapeutic benefits and creating a delightful sensory experience.

Contraindications and Safety Considerations
While comfrey salve offers numerous benefits for external use, it’s essential to be aware of certain contraindications and safety precautions to ensure its safe and effective application.
Internal Use Caution
Comfrey contains pyrrolizidine alkaloids (PAs), compounds that can be toxic to the liver when ingested in large quantities or over an extended period. Therefore, internal use of comfrey, including ingestion or application to mucous membranes such as the mouth or throat, should be avoided. There have been reports of liver damage and other adverse effects associated with internal comfrey use, prompting regulatory agencies to restrict its internal use in many countries.
Avoid Use on Deep Wounds
While comfrey salve can be beneficial for promoting the healing of superficial wounds and skin conditions, it should not be applied to deep wounds or open injuries. Applying comfrey salve to deep wounds can potentially trap bacteria or impurities within the wound site, leading to infection or delayed healing. Additionally, because comfrey works so well at speeding the healing process, it has the potential to heal the surface of the skin before the deep layers of the cut, leading to an abscess.
Pregnancy and Breastfeeding
Pregnant and breastfeeding individuals should exercise caution when using comfrey salve. Although there is limited research on the safety of topical comfrey use during pregnancy and lactation, it’s generally recommended to avoid comfrey products during these periods due to concerns about potential harm to the developing fetus or newborn. Consultation with a healthcare professional is advised before using comfrey salve during pregnancy or while breastfeeding.
Liver Disease or Impairment
Individuals with pre-existing liver conditions or impaired liver function should avoid using comfrey salve. The presence of pyrrolizidine alkaloids in comfrey can pose a risk of exacerbating liver damage or interfering with liver function, particularly when applied over large areas of the skin or for prolonged periods. Those with liver disease or impairment should consult with a healthcare provider before using comfrey salve or any other herbal remedies.
Allergic Reactions
While allergic reactions to comfrey are rare, individuals with known allergies to plants in the Boraginaceae family, such as borage or forget-me-nots, may be at increased risk of sensitivity to comfrey. It’s important to perform a patch test before widespread use of comfrey salve, especially for those with known allergies or sensitive skin. Discontinue use and consult a healthcare professional if any adverse reactions occur.
