Oh, wait, that was in Back in Black? I thought that was in OMD for some reason. My bad!
Besides those two, there's also the X-Men. I mean, Elixir REGENERATED SOMEONE'S HEART. I'm pretty sure Aunt May would not be a problem. Plus, imagine how Otto would react if Spider-Man went to him hat in hand and said, "May Parker is dying and I need your help?" (That would actually be an awesome story.)
