April
19th is National Garlic Day. This tasty bulb, Allium sativum L., a member of the
onion family, is easy to grow and has both medicinal and culinary applications.
As part of the allium family garlic is related to chives, onions, leeks, and shallots.
Garlic can refer to the bulb, which is large and covered in a paper-thin skin,
or the cloves, the individual sections from the bulb. When growing garlic the
cloves are what is used as seed, each clove will grow into a bulb of garlic. Native
to Central Asia, garlic is now grown all around the world although primarily in
Asia with the largest producer being China, followed by India and then South Korea.
Nutritionally
garlic is an excellent source of manganese, an essential trace mineral that is
important for skin, bone, and cartilage formation as well as pituitary gland function
and glucose tolerance. Garlic is also a very good source of Pyroxidine, a B vitamin,
and Vitamin C. Although garlic is available in powder, flake, and chopped form,
to gain the most nutritional benefit it is best to start with fresh, raw garlic.
Culinarily
garlic is used around the world in many different cuisines; it is frequently paired
with onions and tomatoes. Cooking the garlic helps to mellow the flavor. The scapes,
or green shoots, are also edible and often added to stir fry dishes. Even the
flowers are edible and can be used in salads for a mild flavor similar to chives.
Many people like to flavor oils with garlic, if doing this at home it is important
to note that the oil should be refrigerated and used within a week as otherwise
there is a risk of botulism. Commercially sold oils with garlic are treated with
acids or other chemicals to prevent the possibility of botulism. The distinct
taste and smell of garlic comes from the sulfur compounds allicin, alliin and
ajoene. When metabolized these compounds form Allyl methyl sulfide, a gas which
is passed into the blood and disbursed through the lungs and the skin. A temporary
way to cleanse the breath is to eat fresh parsley but this will not remove the
odor from the skin and only works for a short time.
Medicinally
garlic is considered to be antibiotic, anti-histaminic and anti-parasitic in nature.
It is believed to help reduce cholesterol, reduce blood pressure, and provide
other cardiovascular benefits. In 2007 the BBC reported that it may have benefits
for preventing or fighting the common cold. I know that when we feel a cold coming
on in our house the remedy is to chop up a clove of garlic and swallow it down
with a large glass of water. It does seem to be effective. Other medicinal uses
include treatment for acne, food intolerance, candida, respiratory tract infections,
diabetes, and gastrointestinal problems. A recently study published from the Department
of Cardiac Surgery, Heart Center, University of Leipzig in Leipzig, Germany found
that garlic reduced platelet aggregation, a condition where blood platelets stick
together to form a clot.
Very
tasty with lots of health benefits it is nonetheless important to note that garlic
may interfere with anticoagulants, calcium channel blockers, and hypoglycemic
drugs so use caution and work with a health care professional if you are taking
garlic capsules or eating large quantities of it. Large quantities of garlic are
also contraindicated during pregnancy as it may stimulate the uterus and during
menopausal hot flashes as it is considered to have a thermal nature which could
further increase body heat.
