Get Comfrey with It: All About Symphytum Officinale

|  | 

There are some medicinal plants so powerful their reputation precedes them. Such is the case for Symphytum officinale, a type of “super plant” that has been known for its ability to mend bones. Throughout history, people have relied on this ancient herb’s healing properties, and you can still harness its power to relieve bone injuries when used homeopathically.

A Medicinal History of the Symphytum

Symphytum officinale is the Latin name for a perennial shrub in the borage family that grows in wet regions of Europe, Asia, and North America. It’s more commonly known as “comfrey” but is also called “knitbone,” referring to its amazing ability to “knit” bones back together. For over 2,000 years, practitioners of folk medicine would apply poultices, dressings, and salves containing this herb to promote the healing of fractures, broken bones, and other wounds. Comfrey was also used in tea for the treatment of arthritis, rheumatism, and gout.

The roots and leaves of the comfrey plant contain two essential bone-healing substances: Allantoin that fortifies bone and tissue regeneration, and rosmarinic acid, which reduces pain and inflammation. But the plant also has alkaloids that can cause liver damage, so these herbal preparations are no longer considered safe to use.

Homeopathic Bone Mender

Homeopathic Symphytum officinale is made from the comfrey root in a way that safely removes the toxicity. It’s used to help healing after a bone fracture has been reset and relieves the pain caused by bone trauma.* Because Symphytum accelerates the formation of a callus (an essential part of the bone repair process), make sure the fracture has been properly aligned and set before taking this medicine. Symphytum officinalis 6C can be taken three times a day until the cast is removed.

I have used several of your products for years and I’m so very grateful to you! No side effects and they work within minutes after taking them! Thank you so very much!


Hi Deb, thank you for being a loyal customer. We love hearing your feedback!


Hi My name is Donna. I have some questions concerning the single medicines. Does Symphytum officinale, Arnica Montana, and Hypericum perforatum or any of the single medicines cause high blood pressure or any other side effects? Also, it’s for my Mom who feel and broke 3 ribs. They didn’t reset or wrap the ribs. It states on your web to make sure the bones are set before using Symphytum officinale. Is it ok for her to take this medicine if the bones aren’t set?


I also have to recommend this product for bone breaks. I broke 4 ribs in 5 places and this stuff (plus liberal massaging with frankincense oil) worked wonders. I did a six week course, 3 times a day. I suggest it to all my friends with breaks. And sadly, the more we age, the more often we may see bone trauma. Take tai chi to learn how to know where your feet are at all times, and then how to fall should that happen, and then take this if you forget and fall anyway, and have a break someone has set for you. (wink wink) Thanks!!


Thanks for your message. It assured me about need to take Symphytum 6C even though it was a splinter break.


What is the dosage for an adult?!


Hi Marilyn, the dosage for children and adults is the same: Take 5 pellets under the tongue 3 times a day until the cast is removed.

Is post-surgery for an ankle fracture too late? As in, two years post-surgery? Still having serious pain in the area, especially the incision sites.


Hi Chelsea, that might be too long. We recommend talking to a homeopath or natural practitioner for advice.

Susan Johnsonsays:

Which # of Syphtum officinale to take for healing of a fracture. I am taking the 6c right now and it does feel better.


Hi Susan, you are correct, the 6C dilution of Symphytum works best for healing fractures and relieving the related pain.

Gloria Cisneros Lenoirsays:

I fractured the sacrum S3 and my sister in Mexico recommended Symphytum officinale 30c. I hurriedly purchased it and find that I am having less pain in my right thumb, which I damaged from overuse on my iPhone.

Is it recommended for me to take this to reduce arthritic pain? I cannot believe that my right thumb does not have constant pain. Or is there another recommendation for when the sacrum s3 has healed?

Thank you!


Hello Gloria, once the pain has improved and the fracture has healed, you can discontinue the use of Symphytum. There are different remedies for arthritis pain, but their selection is based on specific symptoms you are experiencing. Please try our free Boiron Medicine Finder and choose Joint and Muscle Pain to browse symptoms and medicines best suited for you.

Christina Leisensays:

I’ve read that Symphytum can be taken on a longer term basis for bone density support and osteogenesis. My daughter and I both have Osteogenesis Imperfecta and she has been fracturing often. Is it safe to take this on a longer term basis to increase bone density for someone with a genetic disorder such as Osteogenesis Imperfecta. We have the mildest form, Type I. Thanks for any info!


Hi Christina, Symphytum is indicated the relief of symptoms of bone trauma and not intended to increase bone density. As a homeopathic medicine, it can be taken for a longer period of time when directed by a doctor. We recommend you speak to your doctor or a homeopathic practitioner for more information. If you need help locating a homeopath near you, visit the National Center for Homeopathy to browse their directory.


Can you use symphytum 200 be used for a cracked tooth… Is it best to take internal or swish in mouth?


Hi Marge, we would recommend Hypericum performatum to relieve the nerve pain while waiting for a dental appointment. Take 5 pellets at the onset of pain and let dissolve under your tongue.


I’ve been using Symphtum two pellets daily under the tongue for one year following a severe femur fracture.
How long should continue?

Kelly Olsen-Stankosays:

Hi Janet, Symphytum should be decreased as you notice improvement in the fracture, for example, less pain. If there has been no improvement or you want to use it for a longer period of time, please consult a doctor.


My cat broke a bone in his foot and I’m doing whatever I can to speed his recovery while his leg is splinted. I only have comfrey in the 30c dose. Is that ok to use for him? Should I get the 6c strength and switch to that when I get it? How long after his x-ray shows the bone is mended should I continue it? He’s usually an outdoor/indoor kitty who lives on a farm and is quite active (which is likely how he got the injury in the first place). I’ve also dosed him with arnica and hypericum in addition to CBD for pain. I’ve dissolved the pellets in 1/4 tsp warm water and then administer through a plastic dropper. He’s a pretty good sport about this and we’d both prefer to just dose him in his water. He drinks a lot of water and this is how I’ve administered most of his arnica doses along with Rescue Remedy for animals. Is that ok to do with the comfrey or should I administer it directly into his mouth after I’ve dissolved some pellets? Also, what dose for an 14# animal and is it different for 30c or 6c? Any help appreciated. Thank you!


Hi Summer, since the pathologies and symptoms are different between humans and animals, we recommend consulting a veterinarian skilled in homeopathy. For a list of practitioners in your area, please contact the National Center for Homeopathy at or visit

I have a displaced proximal humerus- treated naturally. is it ok to take 30c even though break is displaced. No surgery recommended. Can it be taken with cissus quadulangaris?
