For fresh burns you apply the salve to herbal leaves or even cabbage leaf if nothing else available and apply to the raw flesh. This is changed 3+ times daily.
This is known as the most painless method for sever burns, even where fingers are burned off, etc.
Dr. Richard Schulze had severe burnt fingers if I remember his story and Dr. Christopher instructed him how to grow new flesh/fingers. I think he shows this in one of his old videos.
The burn salve is based on Dr. Christopher's BF&C salve with added honey, etc. Maybe soon the website owner will offer this rare Amish made salve on the internet with the Amish mans book that was written for those that cure burns at home.
