Quercetin is a flavonoid (also called a bioflavonoid) that has anti-oxidant, anti-histamine and anti-inflammatory properties. During an allergic reaction the body releases histamine. Histamine contributes to inflammation, redness and irritation. Research has shown that Quercetin can “turn off” histamine production and suppress, or at least moderate, inflammation. For this reason, many have coined it “Nature’s Benadryl”.

Raw Honey

Locally grown honey may help prevent seasonal allergies.

A study published in 2011 supports the anecdotal evidence. The study followed 44 patients diagnosed by their physicians with birch pollen allergy. The purpose was to evaluate the effects of the pre-seasonal use of birch pollen honey on the patients’ allergy symptoms and medication use during the birch pollen allergy season. The participants consumed incremental amounts of birch pollen honey from November 2008 to March 2009 and then recorded their daily allergy symptoms and medication use during the birch pollen allergy season, from April 2009 to May 2009. An additional 17 patients serving as the control group took only their usual allergy medication. The results were highly encouraging

Dog Allergies and Lesion Locations

Dogs are taken to the veterinarian for skin problems more than any other reason. Most often they are itchy and that itchiness is typically due to allergies. The text of canine and feline dermatological diseases is large because there are hundreds of skin diseases, however, it can help to start with some generalities when determining the cause

Oral Drops for Dog Allergies

Dogs, like people, can be desensitized through “immunotherapy” using shots or drops that deliver small doses of the allergen to “train” the immune system to tolerate foreign proteins.

Both technologies are now about a century old, but for humans and animals, allergy shots are more commonly used.

Allergies and Antibiotics Connection

There is some evidence that one of the causes lies within the gut. Epidemiological studies have linked changes in the bacteria species present in the colon to the development of allergic diseases.

Mice treated with antibiotics had elevated levels of antibodies known to be involved in allergies and asthma.

Flea Bite Dermatitis

Symptoms of flea bite dermatitis are the result of your Pet’s allergy to flea saliva.

Just as one bee sting can cause an allergic reaction in some people, the bite of only one flea may be sufficient to cause a problem for some Pets.

Allergies and Ear Infections

Allergic symptoms are caused by specialized cells with receptors that react to Ig-E, an antibody made in response to foreign substances. In the spring, trees, flowers, and grasses can all produce allergens that stimulate Ig-E production.

Allergic patients either produce too much Ig-E or are more sensitive to it.  In dogs, the highest concentration is found in the ear canals and skin. As a result, allergies most frequently present as inflammation in the ears or itching skin.

Flea Allergy Dermatitis

Flea allergy dermatitis arises from a negative immune response to flea saliva resulting in subsequent skin lesions and intense itchiness.
