When she was ill, my daughter in New Jersey was told by her doctor to make tea from pine needles. That was three years ago. Pine needle tea has 4-5 times more vitamin C than orange juice. It is also a good source of vitamin A and is an expectorant (thins mucous).
Recommended using white pine, an eastern seaboard variety. Daughter sent me some and it's brewing right now. Wish me luck!
