What is lactucarium?
Lactucin, along with lactucerol and lacturic acid form the basis of lactucarium, a brew with diuretic and hypnotic properties. It has been used in some occasions as a substitute of the opium, because it presents similar effects, although without opium addictive values.
It appears either in the wild lettuce or in chicory, but it has generally been obtained from wild lettuce.
This juice was a very well-known beverage during the XIX century, when addicts to the opium didn’t have this drug.
It is obtained from the latex that the plant produces when being cut. Then it can be taken drunk by diluting it in hot water or, if the liquid is boiled until evaporating all the water, a pasta is formed, that, once dry, can be smoked. This product was taken in doses non superior to a coffee spoonful, or in form of syrups.
Given its toxicity, it should not be used in homemade preparations !!!

Main properties of lettuce
A summary of the main properties of lettuce
EDIBLE PROPERTIES OF LETTUCE
Lettuce is a food that should not habitually lack in our meals. Besides the previous properties, we should keep in mind that its low fat and carbohydrates contents and it is very high in water, so it has got a little caloric power of only 13 Kcal for each 100 g.. Lettuce is very appropriate for weigh loss diets.
Its wealth in minerals, especially potassium that is very necessary to maintain an appropriate level of liquids in the body, together with calcium and phosphorus makes it specially appropriate for the correct well-being of the bones.
It also presents many oligoelements, that are not very habitual inside the vegetable world, as selenium, an antioxidant that has a fundamental paper in the prevention of certain type of cancers, as those of colon, prostate or lungs. It also prevents precocious aging and even helps to combat dandruff. Among the plants that present more proportion of this element we found thistle (Silybum marianum) or valerian (Valeriana officinalis)
It contains many necessary amino acids for the formation of the proteins, some, as alanine, necessary for the construction of the muscular and nervous tissues, other as glycine, for the correct operation of the immunologic system. It presents vitamins C and E, but, it is specially very rich in beta-carotene which is transformed into vitamin A by the liver. This component which appears with more proportion in carrots (Daucus carota) has been demonstrated to have a great influence as antioxidant and anticancerous.

How to eat lettuce?
It is convenient to eat it fresh, so that not to spoil its nutritious and medicinal properties. We have to keep in mind that the internal leaves of lettuce, although more appetizing, present smaller quantity of components that the darker green external ones.
It is very important to wash lettuce properly because it can have traces of organic products, insects, dirt, etc. Gardens have many times fecal matter which has to be eliminated completely not to produce food poisoning.
Toxicity of lettuce: Take care with Lactuca virosa!
Botanical illustration of Lactuca virosa, a plant with toxic alkaloids
Cultivated lettuce (Lactuca sativa) and its mountain variety (Lactuca scariola) don’t present toxicity.
Although the second species is little used in feeding, it is also eatable and its properties are similar to the cultivated variety, although it presents bigger percentages in its components.
Cultivated lettuce is unmistakable, but mountain lettuce can be mistaken with wild lettuce (Lactuca virosa) which presents toxic alkaloids.
To distinguish the two wild species we have to keep in mind that mountain lettuce leaves are place vertically on the stem and the latex that comes off when cutting its leaves is white with yellow tonalities.
Wild lettuce disposes its leaves horizontally to the stem and its latex is white. Lactuca virosa has been used as substitute of the opium, against cough and as antispasmodic and hypnotic (See lactucarium in the right column above)
