I got rid of a large skin tag about size of a small grape and dozen others by putting oreganol on it once or twice a day.
I used it neat with no dilution as did not seem to help when diluted. It did burn but went away after several minutes.
It completely vanished. The smaller ones did not leave scar but this did just the way the doctor does when he freezes them off but since it was dark colored the light scar is much better. I had this ages and thought I would never get rid of it.
