Just to back up Catherine's comment. I have correspondance with a US
doctor who said the PPD reaction they saw was a deep seated allergic
reaction, rather than a chemical burn. Different people react in
different ways. Unfortunately, some people don't get a visible
reaction at all, which is why PPD didn't get thrown out on day one.
But, even those who don't get a visible reaction are probably still
suffering the internal organ damage. The Material Safety Data Sheet
which Catherine linked to tells you all you need to know about that.
It is nasty stuff, and just because you don't get a skin reaction, it
doesn't mean it is safe. The mutagen rating alone is enough to
say "steer well clear". There's enough ways to get cancer that you
can't avoid, without adding in things that you can avoid.
It is doubtful that you're reacting to indigo. At least, I've never
heard of anyone reacting to indigo. I've also never heard of anyone
getting a decent black stain with indigo. Short lived blue-grey
splodge more like.
