Asthma
Asthma is a
condition in which the airways are narrowed because of hypersensitivity to
certain stimuli. During an asthma attack, certain cells in the
airway, particularly the mast cells, release substances such as histamine
and leukotrienes that cause the smooth muscle to contract, mucus secretion
to increase and some white blood cells to migrate to that area. This
results in airway spasm, swelling, and blockage.
Asthma can
be triggered by allergens or irritants, such as animal dander, chemicals,
drugs, dust mites, environmental pollutants, mold, tobacco smoke or by
stress and anxiety.
An asthma
attack often comes with wheezing, coughing and shortness of breath.
Severe symptoms include confusion, lethargy and blue skin color indicating
that oxygen supply is severely limited.
Asthma
attacks can be avoided if the exposure to the specific stimuli is reduced.
Drugs used in asthma treatments are beta-agonists, bronchodilators,
inhaled corticosteroids, antichlolinergics, oral corticosteroids,
leukotriene antagonists.
The
incidence of asthma is growing at an alarming rate over the past 15 years.
Children under the age of sixteen and adults over the age of sixty-five
are most likely to suffer from asthma. The rising level of
environmental pollutants is the most probable cause of higher incidences
of asthma nowadays.
Food
supplements for asthma:
Essential fatty acids (flaxseed
oil, primrose oil)
Essential fatty acids such as flaxseed oil,
fish oil and primrose oil decrease inflammation and improve lung
functions. A small clinical study suggested that children who took
fish oil supplements had some improvements compared to those who took a
placebo pill.
Quercetin
Quercetin is an unique anti-allergy
bioflavonoid. It is a strong antioxidant and can inhibit the mast cells
from releasing pro-inflammatory compounds, including both histamine and leukotrienes.
Quercetin works synergistically with vitamin C so it is better to take
supplements containing both.
Multivitamin and mineral
complex
A good balance of vitamins and minerals is
essential for health. Vitamin A, B complex, C, E have different
actions in the treatment of asthma. They help tissue repair,
decrease inflammation, protect lung tissue and destroy free radicals.
Ginkgo biloba
Ginkgo has long be used by the Chinese to
treat asthma. Ginkgo leaves contain ginkgolides, compounds that reduce narrowing of the airways in response of allergens.
Reishi
Reishi inhibits the release of
pro-inflammatory mediators such as histamines. It also boosts the
immune system and protects the body from infections which may trigger
asthma attack.
