When we were kids my brother had a wart on the side of his ring finger. Nothing would get rid of it. The doctor couldn’t get it to go away, mentioned surgery possibly. Anyhow, our mother took him to a local preacher’s wife and a couple of weeks later it was gone and never came back. My brother was 10-11 at the time and said that he couldn’t discuss the procedure. Finally, about 30 years later he mentioned something abnormal her rubbing’s a piece of thread over it and burying the thread. Sounds crazy and I wasn’t there so who knows.
