Comfrey’s name is a testament to it’s traditional usage in herbal medicine of mending broken bones. Comfrey (Symphytum officinale) is a combination of con firma, meaning “the bone is made firm”, and the word Symphytum is derived from the Greek for “to unite”. It is also known as knitbone.
This herb has been used in the herbal healing of broken bones, sprains, fractures, and bruises for thousands of years. It contains allantoin, a key constituent that helps the cells to repair damaged tissue. The rosmarinic and other phenolic acids play a significant role in it’s anti-inflammatory actions.
Comfrey works by encouraging ligaments and bones to actually knit together. It is usually applied to the skin as an ointment (salve) or an oil to the skin. Comfrey as a cream tends to be watered down so more is needed to obtain the same healing effect. Check ingredients when purchasing to see what has been added. The ingredients should be minimal and you should be able to pronounce all of the ingredients. Comfrey should be the only or primary herb used.
