balsam poplar - Populus balsamifera
The balsam poplar is one of Canada’s hardiest trees, ranging from coast to coast and North into the boreal zone. The buds of the tree produce a sticky, fragrant resin which is known to have a variety of medicinal properties. The ointment made from the balsam poplar winter buds is called “Balm of Gilead” and can be used to relieve chest congestion, treat skin problems, and reduce muscle pains. Honey bees also use the antibacterial properties of resin to self-medicate their colonies. They coat their hives with the resin which helps protect their colony from fungal and bacterial infections. The resin is also highly flammable, making the twigs great for starting fires.
