Healing Properties and Warning

Comfrey root contains allantoin (1%-1.5%), sugars (starch, saccharose, inulin), high amounts of mucilage, glycosides, alkaloids, tannin, choline, and resin. Here are some comfrey root benefits:

1. Wound healing: Thanks to its allantoin content, it has been experimentally proven to stimulate fibroblast proliferation. These are cells of the conjunctive tissues, which form the scar of wounds. Therefore, its use assists in slow-healing wounds, skin sores, ulcers, burns, and whenever stimulation of wounded or bruised tissues is required. Allantoin also acts on the periosteum, a layer of tissue that surrounds the bones and where the bone callus, which closes any breakage, is formed. However, it is not used in traumatology, perhaps because its application on the bone is quite challenging. Moreover, there are other physical measures to close fractures at present.
2. Soothing effect on skin and mucosa: Thanks to its content in mucilage, it promotes the healing of eczema, rashes, and other skin irritations and inflammations.
3. Astringent: Due to the comfrey root’s content in tannin, it dries the mucosa and clots capillary vessels. Mouth rinses with comfrey root are recommended for stomatitis, gingivitis or inflammation of the gums, and pharyngitis.

Whenever internally applied, comfrey root has antidiarrheic and pectoral properties (eases cough), but it is better to use it only in external applications since internally used, it can be toxic.

WARNING! The root, the stem, and the leaves of this plant are toxic when taken orally since the alkaloid symphytine is present in them. This alkaloid has poisonous effects on the liver. Another substance, the glycoside called consolidine, produces paralysis in the central nervous system, and when taken in high doses, respiratory failure is also present in the plant.

Note: In Spain, another comfrey species is called lesser comfrey (Symphytum tuberosum L.), also called tuberous. The properties of lesser comfrey and its applications are the same as those of the common comfrey.

All around, comfrey root is a fantastic remedy. It possesses a soothing, healing effect on every organ it touches. The herb can be used internally and externally to heal ulcers, sores, wounds, and fractures. It helps heal wounds rapidly and aids with cell proliferation. Confrey is highly effective against dysentery, coughs, internal bleeding, catarrh, lung ailments, stomach issues, and ulcerated bowels.

The comfrey root can also aid the pancreas in regulating blood glucose levels. It helps relieve irritations associated with the stomach, small intestine, gallbladder, and kidneys. The herb does an excellent job stimulating pepsin secretion and, in general, is a great help to digestion.

The plant’s content of mucilage is amongst the highest of all herbs. The root’s demulcent properties have been used to treat coughs and lung trouble. It is also used successfully for gallbladder inflammation, emphysema, dysentery, diarrhea, coughs, colitis, calcium deficiency, bronchitis, blood purification, internal bleeding, anemia, arthritis, and asthma.

Externally, the plant can be beneficial in treating sprains, psoriasis, burns, bruises, boils, sunburns, skin rashes, scabies, nosebleeds, leg ulcers, bites, stings, and bed sores. To help against bleeding, use a potent decoction of the root, using ½ to one ounce every 2 hours until the bleeding subsides.

The fresh leaves of the comfrey can be bruised and applied as a poultice to moist ulcers, gangrene, open sores, burns, and wounds. You can also put tea on them. It would be wise to keep some comfrey growing in your garden. It will keep supplying you year after year once it is established. The plant is versatile and prolific. A little piece of the root can reproduce in any moist, shady area.
