WP ointment,pyrogallol and wheat germ oil

I have been using WP ointment very succcessfully on neurovascular corns, mainly plantar, for 30 years with no ill effects. I have heard the claim that pyrogallol is carcinogenic a number of times (along with gentian violet and just about everything else in the world) I cannot find the definitive research for this.
