Allergy Immunotherapy

Ragweed pollen is a common allergen. A single plant may produce about a billion grains of pollen per season, and the pollen is transported on the wind. It causes about half of all cases of pollen-associated allergic rhinitis in North America, where ragweeds are most abundant and diverse.

Johnson Grass is found in washes, along road sides and other areas where there is enough water. It pollenates May through October.

Bermuda grass sheds an abundance of wind-borne pollen. It has severe allergenicity and is one of the most significant grass types in terms of allergy. Those sensitized to Bermuda grass typically display symptoms of allergic rhinitis (hay fever), which affects the nose, eyes, and throat.

This species is native to North America north of Mexico. Allergenicity: Big Sagebrush (Artemisia tridentata) is a severe allergen.
Pollination: Occurs in following seasons depending on latitude and elevation: Summer to Fall.

Russian thistle is a restricted noxious weed in Arizona. It is a common invader of disturbed areas, especially along roadsides. In Arizona it has not been observed moving into undisturbed areas. Nitrates produced during periods of rapid growth may be toxic to wildlife and livestock.

A type of pigweed, this wind pollinated weed is not native to Arizona. It may be found along road sides, in agricultural area, ditches, and vacant fields in the fall.

Allergenic grasses are unequally distributed in different geographical regions. Most allergenic grasses belong to the Poaceae family, which comprises about 9000 species

Snow mold is a type of fungus after snow melts, typically in late winter. Molds live everywhere—on logs and on fallen leaves, and in moist places like bathrooms and kitchens. Some people are allergic to these molds. 

Allergens from cats are found in skin cells the animals shed (dander), as well as in their saliva, urine and sweat and on their fur. Dander is a particular problem because it is very small and can remain airborne for long periods of time with the slightest bit of air circulation. 

Allergens from dogs are found in skin cells the animals shed (dander), as well as in their saliva, urine and sweat and on their fur. Dander is a particular problem because it is very small and can remain airborne for long periods of time with the slightest bit of air circulation.

Spread by wind, mulberry pollen is an important respiratory allergen in many areas, and the tree is considered a heavy pollinator that's potentially very allergenic.

Rodent pets include mice, gerbils, hamsters and guinea pigs. Allergens from rodents are usually present in hair, dander, saliva and urine. Dust from litter or sawdust in the bottom of cages may contribute to airborne allergens from rodents.

Oak trees shed substantial amounts of pollen that spreads via wind, oaks are commonly allergenic and may cause severe reactions. Widely distributed throughout Arizona, oaks produce pollen that is a major cause of hay fever (i.e., allergic rhinitis) symptoms.

Olive tree flowers are primarily wind-pollinated. The flowers release their pollen in the air and wind can carry the pollen for many miles. Pollen is the main reason for olive tree allergies, which are sometimes called hay fever or pollinosis.

Birch trees are wind-pollinating plants, and pollen count can vary year to year based on a number of factors. A single birch tree can produce up to 5 million pollen grains, and the wind will then carry these up to 100 yards. But regardless of the pollen count in the air.

While pine tree allergy is relatively uncommon, there are two main allergens of concern that come from pine trees: pine nuts and pine pollen. Pine pollen is produced when the trees reproduce in the springtime. It is possible for pollen to travel very long distances in the air.

Dust mites, close relatives of ticks and spiders, are too small to see without a microscope. Dust mites eat skin cells shed by people, and they thrive in warm, humid environments. In most homes, such items as bedding, upholstered furniture and carpeting provide an ideal environment for dust mites.

The saliva, feces and shedding body parts of cockroaches can trigger both asthma and allergies. These allergens act like dust mites, aggravating symptoms when they are kicked up in the air. The National Pest Management Association reports that 63% of homes in the United States contain cockroach allergens.

Sensitivities to the plant are not common, but if you're allergic to other plant foods, you should consume alfalfa cautiously. Allergic reactions to the plant could vary from eyes and lungs to gastrointestinal distress. Additionally, alfalfa has a high potential for contamination with bacteria, including E. Coli.

When a person is exposed to horse albumin, it can trigger the immune system to create antibodies known as IgE antibodies. These antibodies trigger an allergic response that can cause symptoms associated with horse allergies, including sneezing and coughing.

Kochia is similar in appearance and pollen allergenicity to russian thistle, except that it has longer leaves that aren't spine-tipped. The genus Kochia, native to Europe and Asia, has been introduced to the U.S. as an ornamental because of their brilliant red fall color and unusual corky bark.

Cottonwood trees spread very tiny, wind borne particles that can affect allergies for people miles around. These trees typically pollinate during the spring along with other tree allergens like ash and oak.

Pigweed is a leafy green plant that has small green flowers at the top that feel course. Pigweed is often found in gardens or abandoned fields so you may come across it in your backyard. Peak pollen shed is late summer to early fall. It is typically found in full sun and dry conditions. 

Sycamore pollen allergy season occurs around the same time as many tree pollen allergies. The season tends to start in early March and will begin to taper off in May, sometimes extending into June. Pollen counts will usually peak around April.Jun 6, 2022

Dock is a great potential cause of seasonal allergies. The pollen travels well in the wind, and has caused many positive skin tests in allergy patients. Since Rumex pollinates in a similar time frame to grass, some allergy sufferers may confuse their allergy to Rumex with allergy to grass.

If you find yourself fighting a mid-winter allergic reaction, elm is a likely culprit. Elm pollen affects allergy sufferers with asthma-like symptoms, itching, sneezing, wheezing, headache, sinus pain, breathing problems, red or tearing eyes, runny nose, itchy eyes and throat, cough, or dark circles under eyes.

Many patients with boxelder tree allergy can experience symptoms when exposed to other allergens such as tree, weed, or grass pollens, making it difficult to determine which pollen is causing the symptoms, especially when pollen seasons are overlapping. This is called cross-reactivity.

If you're sensitized to Timothy grass and have asthma, grass pollen may trigger or worsen asthma symptoms, such as coughing and wheezing. While symptoms are usually limited to the throat, nose, and eyes, some people who are severely allergic to grass may also develop hives upon contact with its pollen.

Walnut pollen is moderately allergenic and sensitizes through inhalation. Walnut California, the western species can cause sensitization more than Black walnut. Pollens can cause allergy through inhalation while nuts can cause food. Walnut pollen allergy can induce symptoms such as asthma and rhinitis.
