No, it isn't.  Black Salve can be extremely invasive and painful, and can leave scars.  There is no ingredient in Perrin's Blend that is similar to blood root, the main ingredient in black salve.  In fact every ingredient in Perrin’s Blend can be bought at a health food store and taken internally. Perrin's Blend is non-invasive, relatively painless, and most of the time leaves no scars. Sometimes there can be inflammation (redness and itching) associated with using Perrin's Blend but many times this is an indication that the place is responding to the Perrin’s Blend. In the case of Lichen Sclerosis, because of the sensitivity of this condition, many times there is burning sensation if the skin is raw and open.
