The Bone Regenerating Potion was taught by Professor Hecate Lafay during Term 26. During the course of the lesson, Lafay explained the purpose of every ingredient.

The potion is used to regrow bones that are removed magically or damaged.


  • 1 gallon of Water Buffalo Milk Cottage Cheese
  • 1/2 cup of bran cereal
  • 2 T Salt
  • 1 chopped asphodel leaf
  • 2 tsp of dragon (Peruvian Vipertooth) marrow
  • 4 T unicorn horn powder
  • A packet of muggle Jell-o gelatin
  • 1 Freshly cut newt (warty newt) tail
  • 2 Crushed sopophorous beans
  • 5 squeezes of Liquid Marshmallow

Explanation of Ingredients

  • Water Buffalo Milk Cottage Cheese has a high concentration of calcium
  • Bran cereal is high in phosphorus, which is also necessary to build strong bones
  • Salt is necessary because sodium is another component of strong bones
  • Asphodel leaves aid in the healing process and have minerals needed for bones
  • Dragon marrow replaces human bone marrow, since it is magical and will adapt to the patient's DNA
  • Unicorn horn powder also has magical healing and regenerating properties
  • Muggle Jell-o gelatin contains collagen protein, an important component of bone growth
  • The freshly cut new tail helps with regenerative properties
  • Sopophorous beans will cause the patient to sleep, especially important since the regrowth process is painful
