I
don't really remember my Dad's Mom, Flora. She died in 1963 and I was 6
years old. But I've heard my Dad talk about her spring tonics all my
life. And the spring vegetables. Dandelion greens,
rhubarb, watercress, asparagus, horseradish. Dad said, and I quote,
"My mother made us eat our vegetables. And every spring she
made us eat the dandelions and rhubarb to clean out our systems. She was
big on the spring tonics."
My
Dad grew up on a farm in Iowa, which meant they lived with a long, cold,
dark winter. And if you happen to be coming out of a northern winter
yourself, you might especially want to heed Grandma Flora's advice. But you
don't have to live in Iowa to benefit from spring tonics. It turns
out, grandma knew what she was talking about.
The
definition of a tonic is something that invigorates, refreshes and
restores. In herbalism, a tonic herb is one that strengthens and
improves overall body function or specific organ function, depending on
the herb. This is pretty much what grandma had in mind when she was doling
out the spring plants at her dining table, even if she wouldn't have known
the technicalities of why they worked.
Dandelion
leaves (1,2), for example, have chemical
constituents
such as bitter glycosides, carotenoids, terpenoids, choline and potassium
salts, that function as both liver and digestive tonics. The leaves
also have diuretic properties which helps the encourage urine flow and
thus, elimination of toxin through the kidneys. And dandelion
promotes bile flow through the gallbladder and has mild laxative
properties. Will you think a little bit differently about that
little yellow flower when you're yanking it out of your back yard the next
time. It qualifies as a nearly magical spring tonic..
Rhubarb
has anthraquinone glycosides which have a strong laxative effect,
increasing intestinal peristalsis significantly and thus helping to
eliminate sluggishness and toxicity of a long, sedentary
winter. Because rhubarb is such a strong purgative, it can
cause abdominal cramping and so is perhaps best taken with a small amount
of fennel or ginger which act as gentle carminatives to soothe and relax
the intestines.
Watercress
contains more sulfur than any other vegetable, except horseradish.
Sulfur-rich foods (others include onion, garlic, legumes, eggs and
cruciferous vegetables) are important in helping the body to bind up and
eliminate toxins. Both the Romans and the Greeks wrote of the
medicinal properties of watercress. It was also written that Persian King
Xerxes fed watercress to his soldiers, to keep up strength and
stamina. Watercress has potent diuretic and digestive properties as
well as antiscorbutic properties (meaning it can help prevent scurvy due
to its high Vitamin C content).
Horseradish,
as already mentioned, has a very high sulfur content. An interesting
fact regarding horseradish is that when the root is unbroken, it has no
odor. It does, however contain, in separate cells a glucoside called
sinigrin, and an enzyme called myrosin, which when they are
combined produce a volatile oil called Allyl. It is the
volatile oil that we smell and associate with horseradish. This
volatile oil is actually only created when the root is scraped or bruised
in some manner, which is enough to bring the cells of sinigrin and myrosin
together. Horseradish is a strong stimulant and when eaten with
foods can help to improve and complete digestion. It is also a
diuretic, increasing urine flow, as well as another antiscorbutic, high in
Vitamin C.
To
these tonics of grandma Flora's, you can add any of the springtime
vegetables that begin to appear at your local farmer's market: asparagus,
artichoke, baby greens, baby carrots, etc. Make your own grandmother
happy and eat up!
