AI ART TO BE GENERATED

PARTS TRADITIONALLY USED

Leaves and the dried milky sap (lactucarium).

CULINARY USES

The very young leaves can be eaten but quickly become exceedingly bitter and tough as the plant matures.

TRADITIONAL USES

The dried milky sap, called lactucarium, was traditionally used for its mild sedative and analgesic properties. It was historically used to promote sleep, calm restlessness, and soothe persistent coughs and mild pain.

GROWING / HARVESTING

Native to Europe but naturalized in many temperate regions. Often found as a weed in disturbed soils. The sap is harvested by cutting the upper stem and scraping off the milky latex as it dries.

SAFETY / CAUTION

Always consult your doctor. In large doses, it can cause dizziness, sweating, and auditory disturbances. Avoid use during pregnancy or if you have glaucoma or an enlarged prostate.
