Hydroxymatairesinol (HMR) is a lignan found in Norway spruce (Picea abies).^[1] It is an enterolactone precursor with anticancer activities. In rats, HMR decreased the volume of induced tumours and stabilised established tumours, as well as preventing the development of new tumours.^[1] It has also shown anti-oxidant properties in vitro.^[1]
