Elecampane is a bottle of a miraculous cure liquid used by one of the Galoshans characters at Hallowe'en and /or Hogmanay. It can cue ills and wounds, bring the dead back to life
Galoshans happened in probably mainly rural Scottish communities back in the day, survives in a watered down form as Guising. The original version was a sort of play, with characters, and dialogue, songs, some dancing. The disguised characters (all home made . old clothes turned inside out etc, turnip lanterns to light the way and scare off bogles) If you check the Kist o Riches / Tobar an Dulchuis (hope I spelled that correctly?)site you should find some Galoshans information?
(In Greenock people still ask each other if they are 'going for their Galoshans' rather than if they are going out guising! - there is an annual Galoshans festival over several days based at the Beacons Arts Centre - not this year obviously!)
