[WARNING!] Someone here recommended using their own urine on a cyst on this forum. It may sound attractive to some of you because of its new-age/ayurvedic connotations but it really is non-nonsensical. Urine contains much bacteria and bacterial infection is on the the main complications with sebaceous cysts. You might as well smear it with garden compost!!
Whatever you do, don't put urine on a cyst.
