An infusion of mānuka leaves, to ease stomach complaints, was a traditional Māori herbal medicine. Kauri trees yield gum, which was exported in the 19th century for its use as a varnish. Chemists studying the ‘natural pharmacy’ of the forests have found unique compounds – including mānuka’s antibiotic leptospermone – which show promise as drugs and other products.
