USDA Hardiness Zone:
Leaf -The dry or fresh leaves are made into a tea for colds and to reduce gas. They smell so nice, that they can be used as an air freshener. Medicinally, angelica leaves are used to help fight a cold, and are said to help prevent motion sickness. I would infuse fresh, cold water with them if I was going to try this remedy.
Stem - Stems are actually candied! After peeling the stems(I have found recipes that say to peel when raw and others that say boil first), use my recipe for crystallized ginger. If you have ever eaten them, please share your experience.
Seed - Burning the seed is said to freshen a room. The seeds are also mixed with stems and used to flavor alcoholic drinks.
Root - In the spring, if one cuts into the crown of angelica, a gummy substance is released. This can take the place of a fixative in potpourri.
