Wild Lettuce is a useful medicinal herb. The whole plant is rich in a milky sap that flows freely from any wounds. This hardens and dries when in contact with the air. The sap contains ‘lactucarium’, which is used in medicine for its anodyne, antispasmodic, digestive, diuretic, hypnotic, narcotic and sedative properties. Lactucarium has the effects of a feeble opium, but without its tendency to cause digestive upsets, nor is it addictive. It is taken internally in the treatment of insomnia, anxiety, neuroses, hyperactivity in children, dry coughs, whooping cough, rheumatic pain etc.  The plant also contains ‘hyoscyamine’, a powerful depressant of the parasympathetic nervous system. An infusion of the fresh or dried flowering plant can also be used. The plant should be used with caution, and never without the supervision of a skilled practitioner. Even normal doses can cause drowsiness whilst excess causes restlessness and overdoses can cause death through cardiac paralysis.  The sap has also been applied externally in the treatment of warts. A homeopathic remedy is made from the plant. It is used in the treatment of chronic catarrh, coughs, swollen liver, flatulence and ailments of the urinary tract.
