Symphytum Comfrey

Symphytum Comfrey is in the plant family Boraginaceae in the genus Symphytum.

The word ‘Symphytum’ is Latin and comes from the Greek ‘symphis’ and ‘symphyo’ which mean ‘growing together’ and from ‘phyton’ which mean plant.

Early Words for Comfrey

The Word “Comfrey” In the middle ages (1275-1325) the word used for comfrey in Middle English was ‘cumfirie’ and ‘conferye’. In Anglo-French the word was ‘cumfirie’. In Old French it was ‘confire’. Those words come from the Latin words ‘conferva’ and ‘confervere’.

‘Conferva’ (confervae) is a feminine, singular noun. It means a freshwater (aquatic) plant with medicinal power. The word appears in Pliny’s “Natural History” (Naturalis Historia), a 77 AD encyclopedia written in Latin by Pliny the Elder, a Roman author and naval commander.

‘Confervere’ (confervo) is an intrasitive verb in the third conjugation. It mean to knit broken bones, to grow together, to heal seethe/boil together. From the “Oxford Latin Dictionary”, 1982.

This drawing is from 'The Tudor Pattern Book' circa 1520-1530 AD. The image on the left is comfrey, on the right is daisy.

Symphytum officinale

Today the comfrey plants you are most likely to find are Symphytum officinale and Symphytum uplandicum or Symphytum uplandica.

‘Officinale’ means it was the official medicinal plant sold in apothecaries and pharmacopoeias in the middle ages (5th- 15th centuries AD).

‘Officinalis’ or ‘officinale’ are Medieval Latin words that mean a plant was (is) used in medicine and herbalism. The word frequently occurs as the second term of a two-part botanical name.

Ancient Greeks and Comfrey

Since 400 BC comfrey root was used in Greece. The Greek historian Herodotus (484- 425 BC) recommended it to stop severe bleeding. Later Greeks used it to heal bronchial (lung) problems.

In the second century the Greek poet/physician, Nicander of Colophon, wrote about comfrey in his herbal book ‘Alexipharmaca’.

The Greek physician Pedanius Dioscorides (40- 90 AD) recommended it for healing wounds, repairing broken bones, and curing lung/stomach problems. He authored ‘De Materia Medica’ (On Medical Materials), a 5-volume Greek encyclopedia about herbs and medicinal substances, 65 AD. This pharmacopeia was used for 1,500 years. It is the most influential and important herbal ever written.

Dioscorides (a Greek) worked for the Roman army as a surgeon. He had to help heal trauma injuries, so he was particularly interested in herbs that stopped bleeding such as yarrow, and in wound repair herbs such as comfrey and calendula.

Galen of Pergamon, a famous Greek physician and philosopher (130- 200 AD), included comfrey in his medical treatises such as ‘Galenou Apanta’.

The first photo is Herodotus. The second photo is 'De Materica Medica' by Dioscorides translated into Arabic.

Romans and Comfrey

Pliny the Elder (23-79 AD), a Roman naturalist and philosopher used comfrey root medicinally.

He wrote: “The roots be so glutinative that they will solder or glew together meat that is chopt in pieces, seething in a pot, and make into one lump.” Pliny found comfrey root to be good as a poultice for binding broken bones together.

Pliny wrote 15 books on medicinal plants including ‘Naturalis Historia’ (Of Natural History) (77–79 BC). It is one of the largest single works (37 volumes) to have survived from the Roman Empire, a great book of ancient knowledge.

"Pliny experimented and documented many uses and the preparation of comfrey for both internal and external use as well as its adhesive qualities. Preparation of the remedy for internal use involved taking the root of the plant and crushing it and mixing it with water or decoction, which is a method of extracting oils by boiling; this would then be taken with wine. A final faster method for respiratory ailments would be to chew the root. They used these remedies for the internal treatment of kidney disease, stomach and intestinal cramps, diarrhoea and lung disease such as lung bleeding. It was used to treat sprains, contusions, fractured bones and aid wound healing."

The above quote is from Eve Maria Thoresen, Faculty of Veterinary Science, Szent Istvan University, Department of Botany, Budapest Hungary, 2013, Symphytum officinale, Common Comfrey (Source: Pliny the Elder - Naturalis Historia, AD 79: Book 27 Chapter 24.)

Early Renaissance (15th- 16th Centuries)

Swiss physician Paracelsus (1493-1541 AD) said: “To what purpose do you superadde vinegar to the root of Comfrey or bole, or suchlike balefull additaments, while God hath compos'd this simple sufficient to cure the fracture of the bones?”

From ‘A New Herball’ by William Turner (1568): "of Comfrey Symphytum, the rootes are good if they be broken and dronken for them that spitte blood, and are bursten. The same, layd to, are good to glewe together freshe woundes. They are good to be layd to inflammation."

Renaissance (17th Century)

John Parkinson (1567-1650) was a Master Herbalist and apothecary to King James I. In his book ‘Theatrum Botanicum: Theater of Plants Or An Herball of Large Extent’ (1640): "The rootes of Comfrey, taken fresh, beaten small, spread upon leather, and laid upon any place troubled with the gout, doe presently give ease of the paines and applied in the same manner, giveth ease to pained joynts, and profiteth very much for running and moist ulcers, gangrenes, mortifications and the like."

English herbalist, botanist, physician Nicholas Culpeper (1616-1654) wrote in ‘Complete Herbal’ (1653) about comfrey roots: “full of glutinous and clammy juice...for all inward hurts...and for outward wounds and sores in fleshy or sinewy parts of the body...It is especially good for ruptures and broken bones.” He mentioned comfrey for fever, gangrene, gout, hemorrhoids, and respiratory ailments.

The first and second photos are 'The Theater of Plants'. The third photo is John Parkinson.

Age of Enlightenment (18th Century)

Tournefort's ‘Compleat Herbal Or The Botanical Institutions’ (1719) gives a long account of the characteristics and "vertues" (virtues) of comfrey.

Tournefort wrote: "cured a certain person of a malignant ulcer, pronounced to be a cancer by the surgeons, and left by them as incurable, by applying twice a day the root of comfrey bruised, having first peeled off the external blackish bark or rind; but the cancer was not above eight or ten weeks standing."

In 1787 English physician Dr. William Withering (1741-1799), and in 1845 naturalist William MacGillivray (1796-1852) wrote about Comfrey in “A Systematic Arrangement of British Plants”.
