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 unadvisable (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, were thus:
- 19 fl.oz. Bat wings
- 20 fl.oz. Armadillo bile
- 16 fl.oz. Wormwood
- 31 fl.oz. Armotentia
- 02 fl.oz. Acromantula venom
- 09 fl.oz. Aconite
- The 28 fl.oz. left are, presumably, water
- Harry Potter and the Half-Blood Prince (film) (Mentioned only)
