Comfrey: properties, uses, and comfrey oil for natural care

There are herbs that carry within them a long history of folk knowledge. Comfrey is one of them. Known internationally as comfrey and botanically as Symphytum officinale, comfrey was traditionally used in poultices, oils, and ointments for the care of skin, muscles, and tired areas of the body.

Its name is connected to the idea of "symphyo", meaning "unite". It is no coincidence that in older herbal traditions it was also referred to as "knitbone". Today, however, we pay more attention: comfrey is valuable for external use, but it is not an herb for internal consumption.

What is comfrey?

Comfrey is a perennial plant of the Boraginaceae family, related to well-known plants such as borage. It originates from Europe and Asia and grows mainly in temperate regions, in moist soils, near streams, meadows or cultivated orchards. The species Symphytum officinale is considered an accepted botanical species and its natural distribution extends from Europe to Western Siberia and northwestern Turkey. (Plants of the World Online) It has large, rough, and fuzzy green leaves, while in spring and early summer it produces small bell-shaped flowers, usually in shades of purple, pink, white, or cream. Its roots are thick, deep, dark externally, and fleshy internally.

Useful parts of the plant

The parts traditionally used are mainly:

The leaves: Usually collected in spring and summer, before or during flowering. They are rich in plant ingredients and are used in extracts, poultices, or oils for external use.

The root: Considered the "strongest" part of the plant in folk herbal medicine. It contains a higher concentration of active ingredients, but also requires greater caution in use due to the presence of pyrrolizidine alkaloids.

Ingredients such as allantoin, rosmarinic acid, tannins, triterpenic saponins, and silicic acid have been identified in the leaves and root, which are associated with the traditional use of the plant in skin care products and soothing preparations. (National Center for Biotechnology Information)

Properties of comfrey

Comfrey has traditionally been associated with skin, muscle, and joint care. Its external uses mainly concern:

Soothing care: In the form of oil, ointment, or cream, it can be used for massage on areas that feel tired.

Care after minor injuries: Traditionally used for bruises, contusions, and areas with local discomfort, always on intact skin.

Support for skin regeneration: Allantoin, one of its known ingredients, has been linked to skin care and reconstruction.

Emollient and protective action: In fatty extracts, such as comfrey oil, it offers a rich texture and nourishing feel, especially when combined with beeswax, olive oil, or other vegetable oils.

The European assessment for comfrey root mentions its traditional external use for bruises, sprains, muscle and ligament strains, while older European sources describe it as helpful in emollient and protective skin care. (European Medicines Agency (EMA))

Comfrey can be utilized in various ways, always for external use.

1. Drying of leaves or root

Leaves are collected clean, without moisture, and spread in a shaded, ventilated place. The root needs thorough cleaning, chopping, and more careful drying, as it is fleshy and retains moisture.

2. Oil extraction

The most popular form for cosmetic use is comfrey oil. Leaves or roots are extracted in a vegetable oil, such as olive oil, sunflower oil, almond oil, or grapeseed oil. The result is a herbal oil that can be used alone or as a base for ointments and balms.

3. Poultice

In traditional use, fresh leaves were crushed and applied externally. Today, this use requires caution, cleanliness, and avoidance of application to open wounds.

4. Ointment or balm

Comfrey oil can be combined with beeswax to make a rich ointment. This is one of the most practical ways to use it, as the product is easy to apply, stays on the skin, and provides a protective texture.

Preparation: comfrey oil

Comfrey oil is a herbal oil for external use, ideal for massaging areas that need care after exertion. It can be used as is or incorporated into an ointment with beeswax.

Simple preparation of comfrey oil

Materials:

• 1 part dried comfrey, leaf or root
• 4–5 parts vegetable oil, such as olive oil or almond oil
• Clean glass jar
• Muslin cloth or filter
• Dark glass bottle

Instructions:

Place the dried comfrey in a clean, dry jar and cover completely with the vegetable oil. Close tightly and leave the jar in a warm, bright spot, away from direct intense sunlight, for 3–4 weeks. Shake gently every few days.

At the end, strain very well to ensure no plant residues remain in the oil, and store in a dark bottle. The oil should be kept in a cool, dark place.

Idea for a comfrey beeswax balm

For a more stable texture, we can make a balm:

• 85 g comfrey oil
• 12–15 g beeswax
• 1 g vitamin E, optional
• optionally a few drops of lavender or rosemary essential oil, at a safe low dosage

Melt the beeswax in a double boiler with the comfrey oil, stir, add vitamin E, and fill clean jars. Let it cool and solidify.

How to use comfrey oil

Comfrey oil is applied only externally to clean, intact skin. It can be used with a gentle massage on areas such as knees, shoulders, lower back, elbows, or areas that have been strained. A small amount is sufficient; a few drops are enough to work the product well into the skin.

Avoid use on open wounds, deep cuts, irritated skin, during pregnancy, breastfeeding, and in children without expert guidance.

Important caution: not for internal use

Comfrey contains pyrrolizidine alkaloids, substances that can be toxic to the liver when taken orally. For this reason, internal use, such as tea, capsules, tinctures, or comfrey powder, is not recommended. The LiverTox database of the NIH states that comfrey, when taken orally, has been linked to severe liver damage and hepatic sinusoidal obstruction syndrome. (National Center for Biotechnology Information) The approach is clear: comfrey belongs to the herbs that can have a place in carefully formulated products for external use, not in beverages or internal preparations.

Comfrey in Mellifora's natural care

At Mellifora, we love herbs not only for their tradition, but also for the responsibility they demand. Comfrey is a characteristic example of a plant with a great history and special power, which requires proper knowledge and respect.

A comfrey oil or balm can be a rich massage preparation for areas that feel tired, strained, or tight. When combined with olive oil, beeswax, St. John's Wort oil, or other herbal extracts, it creates a deeply nourishing and protective care, inspired by the wisdom of nature.

Thus, at Mellifora, we have added comfrey oil to our two special preparations intended for the relief of muscle pain, sprains, and joint pain, the herbal massage oil and the arnica beeswax balm.
