Armadillo Bile Mixture was a potion. It appeared to be a corrosive substance, as the lid was to be kept closed at all times and contact with skin was inadvisable (if there was contact with the skin then one should wash the affected tissue with unicorn hair immediately).
Despite the name might lead one to think otherwise, the main component of Armadillo Bile Mixture is Armotentia.
The ingredients, for 125 fl.oz. of potion, are as thus:
