Effectually, no.
Black pepper is a common DIY temporary fix for radiator leaks. You typically need about 1-2 tablespoons of ground black pepper to pour into the radiator to help seal the leak. It is important to note that this is just a temporary solution and you will need to have the radiator properly repaired.
Ground Black Pepper will, in deed, stop a small radiator leak. I've done it many times. I've NOT experienced any bad effects from doing this. If (when) leaks persist, it is time for a new radiator.
