Flobberworm mucus, alternatively spelled Flobberworm mucous[1] or Flobber Mucus for short,[2] is the slimy green mucus exuded from the Flobberworm, often used to thicken potions.[3]


A popular potion ingredient, it is used in the Wiggenweld Potion[4], Herbicide, and the Sleeping Draught. Flobberworm mucus is sold at the Apothecary, costing one Galleon for eight bottles.[3] This mucus is also spread all over the roof beams on the Hogwarts attic.[2]


On 2 December, 1926, The New York Ghost published an article in which Healers claimed that Flobberworm mucus could boost the immunity of infants.[5]
