Lactuca canadensis – Canada Wild Lettuce

Wild lettuces can be identified by the hairs on the bottom of the leaf’s central vein. In Lactuca canadensis, the hairs are less consistent than in other species of Wild Lettuce.

The young leaves and stems are edible but should be eaten in moderation. Leaves can be eaten raw in a salad or boiled to remove bitterness.

Wild lettuce produces a milky sap, called Lactucarium, from its leaves, stem, and roots when cut. Lactucarium is an analgesic and sedative. It has been used in the treatment of insomnia, osteoarthritis, and anxiety. The concentration of Lactucarium is highest when the plant is in bloom.
