Iodine mixed with olive oil (or flaxseed oil) 1:5 ratio cured my fissures. I have this symptom often if stool is hard. Whenever I got bleedings due to the hard stool, I washed /dryed the area and apply this mixture with my finger tip. I had to feel the scratched area with my finger so that I could apply it properly to the right area. Then I clean / remove the excessive mixture outside because it may stain the underwear. Usally, the next day, I feel OK but I do this 2 to 3 days to be sure.
