Originally called “knitbone” and is also known as Boneset and Bruisewort
In herbal medicine, we have used the roots and leaves of Comfrey, a fast-growing, long-lived plant that forms a ‘rosette’ of lance shaped leaves (up to 30cms long) that put up a tall flowering stem up to 1.5 meters high. Comfrey leaves have many health benefits; they are rough textured and covered in short stiff hairs. The roots are also very famous in herbal medicine, they are short, thick, many-branched and they have a black surface with a white, chewy, mildly sweet interior.
The root and leaves of the comfrey plant have been used in traditional medicine in many parts of the world. In Japan, the plant has been harvested and used as a traditional treatment for over 2,000 years. It was originally called “knitbone” and is also known as Boneset and Bruisewort.
