is necessary to stimulate the kidneys to increase micturition, in illnesses like:
obesity, arterial hypertension, dropsy (accumulation of liquids in the
body with swelling of tissues), edemas, kidney pain, nephritis , kidney
stones, renal inadequacy, inflammation of the bladder (cystitis), etc. Equally

The lettuce has a tranquilizing effect. It helps to calm the nerves, to
control palpitations and to sleep better at nights, avoiding the insomnia. (Eat
a good lettuce salad, with olive oil before going to sleep. This property is increased
if we carry out a decoction with 50% of lettuce leaves and we drink a couple of
glasses a day, one in the mornings and another one before going to bed) The component
that grants it this property is the lactucin, one of the main components of the
juice of the lettuce.
related with this property is the supposed anaphrodisiac values of this vegetable
that grant this plant the property of appeasing the sexual appetite, property
that was already stood out by Plini, a Roman savant whose scientific thoughts
were unquestioned until Middle Ages (Eat lettuce salads)
- Respiratory system diseases: The
decoctions of lettuce leaves are interesting for the affections of the respiratory
tract, helping to combat cold, asthma attacks and bronchial spasms. If
the plant is allowed to germinate, one can take profit from floral stems to carry
out the same decoctions with more outstanding properties that those of the leaves. (Decoction of 100 gr. of lettuce in 1 liter of water. Three cups a day)
To combat cough, it can be carried out a lettuce syrup ( See recipe) Take
a couple of heated glasses a day.

very prolonged menstruations an infusion during half hour of 100 g of tender leaves
for a liter of water can be carried out. Drink 2 or 3 cups a day.
In external use, it has emollient properties so that it can be used to mitigate
the pains produced by blows, twists, sprains, bruises, etc. (Decoction
of tender leaves during 15 minutes in water. Filter it , leave it to become cool
and apply like a cataplasm. These properties are increased by adding some drops
of olive oil to the pasta.) ( Another juice preparation is obtained by mashing
the plant. Filter it and apply on the aching area)
The analgesic properties of lettuce can be used to mitigate the pain of the sunburns (Decoction of lettuce leaves in water for 15 minutes. Cool and apply the liquid with gauze on the affected are

etc. ( Boil during 6 minutes 50 gr of leaves in 1/2 liter of water, with some

Edible properties: The
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 its high contents in water, what provides it a caloric power of only 13 Kcal
for each 100 g., are very appropriate for weigh loss diets.
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 the 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 the dandruff.
Among the plants that present more proportion of this element we found the thistle
( Silybum marianum ) o the valerian (Valeriana
contains many necessary amino acids for the formation of the proteins, some, as
the alanine, necessary for the construction of the muscular and nervous tissues
, other as the 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 the carrot (Daucus carota) has been demonstrated to
have a great influence as antioxidant and anticancerous.
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, although more appetizing,
present smaller quantity of components that the darker green external ones.

( Lactuca virosa)
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. The cultivated
lettuce is unmistakable, but the mountain lettuce can be mistaken with wild lettuce
(Lactuca virosa )which presents toxic alkaloids.
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. The 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
: Lactucin has sedative, 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 the 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.
product can take in doses non superior to a coffee spoonful, or in form of syrups.
its toxicity, it should not be used in homemade preparations !!!
