Closely related to chicory,
dandelion is a common plant worldwide and the bane of those looking for the
perfect lawn. The plant grows to a height of about 12 inches, producing
spatula-like leaves and yellow flowers that bloom year-round. Upon maturation,
the flower turns into the characteristic puffball containing seeds that are
dispersed in the wind. Dandelion is grown commercially in the United States and
Europe. The leaves and root are used in herbal supplements.
Historical
or traditional use (may or may not be supported by scientific studies):
Dandelion is commonly used as a food. The leaves are used in salads and teas,
while the roots are often used as a coffee substitute. Dandelion leaves and
roots have been used for hundreds of years to treat liver, gallbladder, kidney,
and joint problems. In some traditions, dandelion is considered a blood
purifier and is used for ailments as varied as eczema and cancer. As is the
case today, dandelion has also been used historically to treat poor digestion,
water retention, and diseases of the liver, including hepatitis.
The
principal constituents responsible for dandelions action on the digestive
system and liver are the bitter principles. Previously referred to as
taraxacin, these constituents are sesquiterpene lactones of the eudesmanolide
and germacranolide type and are unique to dandelion. Dandelion is also a rich
source of vitamins and minerals. The leaves have a high content of vitamin A as
well as moderate amounts of vitamin D, vitamin C, various B vitamins, iron,
silicon, magnesium, zinc, and manganese.
Animal studies show, at high
doses (2 grams per kg of body weight), the leaves possess diuretic effects
comparable to the prescription diuretic furosemide (Lasix). Since clinical data
in humans is sparse, people should seek the guidance of a physician trained in
herbal medicine before using dandelion leaves for water retention.
The
bitter compounds in the leaves and root help stimulate digestion and are mild
laxatives. These bitter principles also increase bile production in the
gallbladder and bile flow from the liver. For this reason dandelion is
recommended by some herbalists for persons with sluggish liver function due to
alcohol abuse or poor diet. The increase in bile flow may help improve fat
(including cholesterol) metabolism in the body.
As a general
liver/gallbladder tonic and to stimulate digestion, you can take 35 grams
of the dried root or 510 ml of a tincture made from the root can be used
three times per day. Some experts recommend the alcohol-based tincture because
the bitter principles are more soluble in alcohol.
As a mild diuretic or
appetite stimulant, 410 grams of dried leaves can be added to a 250 ml (1
cup) of boiling water and drunk as a decoction;8 or 510 ml of fresh juice
from the leaves or 25 ml of tincture made from the leaves can be used,
three times per day.
Dandelion leaf and root should be used with caution
by persons with gallstones. Persons with an obstruction of the bile ducts
should avoid dandelion altogether. In cases of stomach ulcer or gastritis,
dandelion should be used cautiously, as it may cause overproduction of stomach
acid. Those experiencing fluid or water retention should consult a
nutritionally oriented doctor before taking dandelion leaves. The milky latex
in the stem and leaves of fresh dandelion may cause an allergic rash in some
individuals.
Certain medications interact in a positive and/or negative
way with dandelion. Check with your doctor.
To grow Dandelion,
plant seeds in 3 -4 inch starter pots as opposed to seed trays, since the long
taproot makes it difficult to remove from the smaller container. The seeds will
germinate best if you sprinkle them on the surface of the soil, and just cover
them with a thin layer of perlite. You can also cover with a paper towel, but
should use some plastic wrap to help maintain moisture
levels.
Dandelions are extremely prolific, so take care not to let them
take over your lawn!
They'll even grow from just a section of the
root!
If you are growing dandelion to use the leaves in a salad, use the
youngest plants, as older ones may be bitter. Continue to pinch off the
flowers, and harvest the leaves. The flowers have been used for many years to
make dandelion wine, and beer,
In the fall, dig up the roots for winter
salads, or chop them up and boil them for use as a coffee
substitute.
Dandelion leaves are known to be very high in vitamins A, B,
C, and D, are known as a blood cleanser, and are higher in vitamin A than
carrots! It is also rich in potassium
