Cursing has been around for thousands of years. Up until a few hundred years ago, there were plenty of shamans and other practitioners of the magic arts available to remove curses. But the lack of practitioners in more recent times means many ancestral curses remain in place and are continuing to have effects.
Removing curses, especially those placed many years ago, is a specialized skill. The practitioner and their guiding spirits locate the origin of a curse which is then very carefully dismantled, leaving the previously affected person free from its consequences. Clients have reported significant positive changes in their life after being freed from curses.
