Nanny Mihi's grandchildren excitedly visit her every school holidays. Only this time they arrive with colds... Nanny takes the kids around her forest and garden, showing them plants that can make themfeel better. They find kawakawa and make tea, manuka to put in the bath and clear their stuffy noses, koromiko to help their headaches, and cabbage tree leaves to help with the cuts and scratches they get in the forest. By the time they're well, Nanny is tired and scratched from their foraging - and the kids know just what she needs!
