Byron uses drawing salve, AKA "black ointment." Drawing salve is a skin cream with Ammonium bituminosulfonate which is made from oil shale and, apparently, nobody really knows how it works.
I use whatever is around the house, which is sometimes hydrocortisone cream but is usually diaper rash cream, the kind made with cod liver oil and zinc oxide. Both work very well for me. What do you use?
Biking Bis has a good article on saddle sore prevention.
P.S. No, I will not post photos of my saddle sores.
