For thoughts which go round and round in one's mind, like a hamster on a treadmill, not working towards resolution, but stuck in a repetitive pattern, conversations and episodes being continuously replayed and argued or churning thoughts, that cause insomnia and disrupt constructive activity. This essence will break the repetitive pattern which locks mental energy into non-productive activity, allowing creative energy through, clearing the mind, calming the agitation or worry and bringing inner peace. It is also use-ful for clearing the mind for meditation.
