The topic of black salve can be heated one at the best of times in circles where people know what black salve is. This documentary (link to full version in the description below) covers interviews with a host of different people who claim to have used black salve, and it even goes so far as to disclose the black salve ingredients.
I have personally tried black salve on a number of suspect patches of skin and only on one occasion was there as reaction that caused something to be 'pulled out' of my body. It was only a small spot, but after treating it with sea moss gel you would never know that there was anything there.
The batch I was given was made with the same black salve ingredients that are disclosed in this video.

Understanding what goes into this product is important as it will help you further investigate the topic with a better basis of being informed.
Sometimes referred to as black sav or black sab, it is interesting to consider that this is deemed to be suitable for use on animals, but not humans. However, that seems to be the status quo in a society where cosmetics and other products are still tested on animals.
