Toxicity and adverse effects Ĭomfrey contains pyrrolizidine alkaloids which are toxic compounds readily absorbed via the stomach or skin, and have potential to increase the risk of fatal liver toxicity. In Europe as of 2015, there were no comfrey products for oral use, and those for topical uses to treat bruises or joint pain were evaluated as having risk of liver toxicity. Ī 2013 review of clinical studies assessing the possible effect of comfrey on osteoarthritis found the research quality was too low to allow conclusions about its efficacy and safety. The leaves were also thought to be edible as a vegetable, similar to spinach. John Gerard, an English herbalist (1545–1612), mentions "the slimie substance of the roote made in a possett of ale" would help back pains. In folklore, Symphytum officinale roots were used in traditional medicine internally (as an herbal tea or tincture) or externally (as ointment, compresses, or alcoholic digestion ) for treatment of various disorders, including commonly as a treatment for reducing the pain of osteoarthritis. Although, it has a long tube, meaning only insects with long tongues reach the nectar, some bees have been known to bite into the side of the flower to reach the nectar. The plant produces significant nectar when compared to other UK plants tested. Symphytum × uplandicum flowers later than S. × uplandicum is generally more bristly and has flowers which tend to be more blue or violet. asperum, Symphytum × uplandicum, also known as Blue Comfrey, or Russian comfrey, which is widespread in the British Isles, and which interbreeds with S. Ī common hybrid is formed between Symphytum officinale and S. They are coiled at first and then open out. Between May and June it bears small bell-shaped flowers of various colours, typically cream, white, pink or purplish. The leaves on the stem have margins which extends down the stems. It is a perennial herb with a black, turnip-like root and large, hairy broad leaves. The hardy plant can grow to a height of 1–3 ft (0.3–0.9 m). Description and botany Ĭomfrey is a perennial plant found in moist grasslands in western Asia, Europe, and North America. Also the roots could be mashed then packed around a broken limb, when dried they formed a hardened 'plaster cast'. Its early common names, knitbone or boneset, reflect its historical use by poultices of leaves and roots to treat sprains, bruises or bone fractures. Over centuries, comfrey was cultivated in Asia, Europe, and the United Kingdom as a vegetable and herbal medicine. Internal or long-term topical use of comfrey is discouraged due to its strong potential to cause liver toxicity. The flowers are mostly visited by bumblebees. It occurs elsewhere, including North America, as an introduced species and sometimes a weed. It is locally frequent throughout Ireland and Britain on river banks and ditches. It is native to Europe, growing in damp, grassy places. Other English names include Quaker comfrey, cultivated comfrey, boneset, knitbone, consound, and slippery-root. To differentiate it from other members of the genus Symphytum, this species is known as common comfrey or true comfrey. Along with thirty four other species of Symphytum, it is known as comfrey.
#WHITE FLOWER COMFREY FREE#
This is probably going to be the best approach.especially if I advertise free "you dig" comfrey.Symphytum officinale is a perennial flowering plant in the family Boraginaceae. Start fresh beds for propagation new and keep better track of my plants for sale. I'm wondering if I just begin the process of digging and moving it all over the property now. This comes from +20 years experience in the green industry - but I can't propagate and sell from this bed.
Personally - the differences I can see between Bocking 4 and 14 are negligible. Pure speculation, but it may be possible the plants are just showing different expressions from the different microclimates?
It has been in the ground for over 5 years. I was told by the person who planted it that it all is blocking 14. Do you have any idea if it's bocking 4, 14 or officinale? The leaves on your white variety look different than mine. And a second white one popped up between two apples trees.

Right smack in the patch of blue and pink flowered plants. Brian Jeffrey wrote:This year I have a clump of white flowered comfrey.
