Used for: constipation, dry cough and chest tightness, and easing childbirth. Its light wood made canoe floats and its bast made cordage.
How to use: the inner bark and the sticky flower buds are steeped in warm water into a slippery, mild drink taken a little at a time. A blossom or two was given to children as the gentlest laxative there is.
