OK, now I remember.
I used it for a while when I couldn't afford my lidocaine prescription.
As I recall, it wasn't as effective as 5% Lidocaine, but it did have a noticeably beneficial impact on the pain associated with anal excoriation and butt burn.
I'm going to get some and use it in those instances where lidocaine is perhaps overkill, and the nupercainal would do the job.
Thanks!
