I have been reading a number of articles on Amish Burn Treatments using B&W Ointment and Burdock Leaves.

I general B&W ointment is applied to the burn and to the back of the burdock leaves. The leaves are applied to the burned area as a dressing. The leaves are replaced every twelve hours.

I'll post some of the articles hear.
