I know Chickenpox is not as common as it once was but boy do I remember when my oldest son got it. I was pregnant with my second child and I got it too for the second time. It was a bit uncomfortable for me but my husband had never had them. He and his cousin caught them and they were miserable until I came up with this to use for them.
This would probably be good for any kind of itchy rash that you may have.
