Boracic lint

Boracic lint was a type of medical dressing made from surgical lint that was soaked in a hot, saturated solution of boracic acid and glycerine and then left to dry.

It has been in use since at least the 19th century,^[1] but is now less commonly used.

The term boracic lint, or often just "boracic", pronounced "brassic", is also used as Cockney rhyming slang for having no money. Boracic lint → skint.^[2]
