Long
valued both as a food and as a medicinal herb, watercress, or Nasturtium
officinale, grows in dense patches along the banks of clear streams
and ditches, by springs and in marshy meadows. The herb's greatest
power is found in its sweetly sharp, pungent leaves, best gathered
before flowering. They are rich in vitamins A, C and D, as well
as in antibacterial agents and minerals. Watercress is well known
as a digestive stimulant and a diuretic. Tea and juice made with
the fresh leaves are considered to be beneficial as spring tonics,
as cleansing agents for urinary tract infections and as treatments
for liver damage, gallstones and bronchitis. The plant is always
used fresh, and it should never be harvested from polluted water
or areas frequented by livestock. Instead, buy plants grown in commercial
beds.
Preparation
of the tea
Pour 1 cup of hot water over 2 tsp. of chopped fresh leaves; steep
for 15 min. and strain. For a cold infusion that preserves the vitamins,
steep 1 oz. of fresh leaves in 4 ¼ cups of cold water overnight.
Strain; heat slightly. In both cases, drink 2 cups a day. Watercress
should not be dried; it will lose nearly all its active medicinal
components. Because it is a diuretic, it should not be used daily
for extended periods.
Therapeutic
effect : Watercress contains mustard oil glycosides and essential
oils, which have a strong antibacterial effect and are beneficial
for healing urinary tract infections and bronchitis. Because of
its high content of vitamins A, C and D and of iron, potassium and
iodine, watercress promotes blood cell formation; aids wound healing
and fortify the stomach.
For urinary
tract problems
With its high potassium content, watercress tea assists the kidneys
by increasing the production of urine. In other words, it acts like
a diuretic. Thus, the urinary tract is cleansed and bacteria is
eliminated. The mustard oil glycosides and the essential oils also
kills bacteria. Drinking 2 cups of the tea daily is also beneficial.
To fortify
the stomach
The mustard oil glycosides, vitamins and bitters in watercress tea
foster production of the stomach juices that promote digestion.
Consuming too much, however, can upset the stomach. Do not drink
more than 2 cups s day.
Extra
tip! : Because of a high iron content,
both watercress tea and watercress juice boost blood cell formation.
They are therefore, a good therapy for people with anemia.
Medicinal
Uses

for chronic bronchitis and a productive cough. For the wine infusion,
very lightly simmer 2 tbsp. of fresh leaves with 1 cup of white
wine for about 10 min. strain. Drink 1 glass of the mixture in the
evening.
To strengthen
the thyroid gland
Because of its high iodine content, watercress has a strengthening
effect on the thyroid gland. The plant's vitamins A, C and D, also
promote gland healing. Drink 2 cups of watercress tea a day.
For gallstones
Because of its effectiveness as a stimulant for the digestive system,
traditional medicine has recommended drinking watercress tea to
