Lovage
Levisticum officinale

Ancient Greeks and Romans used to chew on lovage seeds to aid digestion, and lovage stems were sometimes candied for a special treat. Lovage's name comes from its inclusion in old recipes for love potions, which also accounts for this feathery plant's other common name — "love parsley." On a more practical note, lovage stalks DO make good drinking straws — they are hollow and taste a lot like celery. Since at least the 14th century, lovage root has been a popular folk herb for digestion. Even now, lovage is a principle ingredient in many teas sold in Europe for this purpose.
