A poultice of comfrey or made into an ointment has done amazing & 'quick' healing for me when I tore ligaments and broke bones. I used it many years ago when I did not know enough to add other herbs (as are in the BF&C formula) or therapies such as castol oil packs. All I know is that comfrey did the job!
This post talks about the use of BF&C and how to heal a serious injury. I hope you will find some useful information there and are soon on the mend.
