Alyssa listened as she heard the others give their answers. Then she thought of something.'Yes add that the thing that we are allergic to. But would we add something of ourselves as well so that the potion knows for whom the ingredients are made of.'

So Alyssa raised her hand and asked."Professor would we add something of ourselves too, like for example our hair. So that there's something of what is making ourselves allergic in the potion, as well as, something of ourselves that is reacting to that substance in that same potion?" Alyssa knew that this was a wild guess but hoped that she was right. If not, it was still worth a try.
