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.
