Douglas Fir resin is found in blisters over the trunks of young trees. They are easy to squeeze and exude a sweet, aromatic but colourless liquid about the same consistency as runny honey. It has antiseptic, antibacterial qualities and is ideal for the sealing of cuts, grazes and burns. In fact it can glue cuts together to help stop bleeding and the ingress of dirt: a challenge when you are out in the wilderness.
