UK & Isle of Man Folklore

  • Couch Grass has long been used in traditional herbalism, though specific folklore ties in the UK and Isle of Man are sparse.
  • In Isle of Man, where grass and plant symbolism is deeply tied to fertility and protection (particularly in folk magic), Couch Grass could be seen as a protective plant. Its roots, with their creeping nature, were sometimes associated with the idea of earthly protection and strength in folktales.
  • The plant has been used in herbal remedies for soothing, cleansing, and as a mild tonic, fitting with the holistic health practices found across the UK.
