Is it normal to wonder if leeches could fix a cysts, acne, boils, infections?
Leeches suck out blood but have been used for medical uses. A cyst is an infected area. Its collected bacteria and germs collecting under one area. Things like this you are not suppose to pop or they might spread. If a leech sucks out your infected blood it would also be sucking out your infection. If the infection was digested none is lingering in your system. So you would have successfully removed it without leaving any trace left.
