Natural Anti Histamine – Quercetin

Quercetin is being referred to as a biological response modifier. When I was first told about this reference I had no idea what it meant. First, it has to be realized that quercetin is a flavonoid and they are generally referred to as nature’s biological response modifiers. This is because flavonoids have an ability to modify the body’s reaction to other compounds, such as viruses, allergens, and carcinogens, as evidenced by their anti-inflammatory, anti-allergic, anti-viral and anti-cancer properties.

Quercetin demonstrates a strong anti-inflammatory activity due to direct restriction of a number of the beginning processes of inflammation. Quercetin restricts both the manufacture and release of histamine and other allergic and inflammatory compounds. Quercetin appears to be useful in virtually all inflammatory and allergic conditions, i.e., asthma, hay fever, rheumatoid arthritis and lupus, and this would include diabetes and cancer.

Quercetin has anti-oxidant properties, and as a flavonoid, it is a very powerful anti-oxidant in giving dramatic protection against oxidative and free-radical damage. Quercetin also exerts a vitamin C- sparing action.

How does quercetin compare to synthetic anti-histamines?

In the United States, synthetic anti-histamines are big business, as these over-the-counter drugs are the major players along with prescription drugs. Anti-histamines and nasal decongestants are used many times to self-treat allergies; generally this only brings a limited success. Synthetic anti-histamines biggest general problem seems to be their mechanism of action. This happens because anti-histamines do not restrict or block the release of histamine. Rather they block the action of histamine at the cellular receptor sites. Because histamine functions in the brain to maintain alertness, anti-histamines generally cause drowsiness; and this is a major side effect. This side effect has caused problems for the drug companies. To overcome this problem, the pharmaceutical companies have developed prescription anti-histamines that do not produce drowsiness but they do have other serious side effects.

There is an obvious need for an effective natural alternative to the synthetic anti-histamines. Quercetin fills the bill. In contrast to anti-histamine drugs that block the binding of histamine to cellular receptors, quercetin research has shown that it restricts the release of histamine to cellular receptors and other inflammatory compounds. When these chemicals are restricted, quercetin greatly limits the allergic/inflammatory response. The bonus is there are no side effects have been reported with quercetin.
