Introduction[]

Bubotuber pus is a thick, yellowish green liquid, which smells strongly of petrol. It is very valuable, and can be used as an effective remedy against acne.

From the Story[]

Harry Potter and the Goblet of Fire[]

Discovered in chapter 13, Mad-Eye Moody[]

Bubotuber pus is collected by squeezing the swellings on Bubotuber plants. It can do funny things to the skin when undiluted, and should be collected whilst wearing dragon-hide gloves.

Discovered in chapter 28, The Madness of Mr Crouch[]

When Bubotuber pus comes into contact with bare skin, it causes large yellow boils to erupt all over the area. When the pus spills over Hermione's hands, her hands are so thickly covered in the painful sores it looks as though she is wearing a pair of thick, knobbly gloves.
