It makes perfect sense now! That has ALWAYS given me fits! I KNEW there was a reason it feels so good and I think this is, in all likelihood, that reason! FINALLY! That has bothered me my whole life as one of the curiosities that sparked my interest in alternative medicine! Since I was a kid and told to "stop scratching" every time I got a skeeter bite or anything else that felt so good to scratch!
We had a neighbor when I was a kid - Gwen. She was an older woman and a missionary who was always "off to Guam" - "The Gwen of the Guam". She could make homemade bread out of just about anything - or just about anything out of practically nothing at all and knew all sorts of things about herbs and plants. I wish I could tell her this as she agreed with me that it appeared universally so that scratching feels good and must have a purpose.
