At times we are asked about allergens other than cedar. In order to get more information disseminated regarding bad allergens, we have undertaken to highlight other allergens as they create reactions. At this time ragweed is such an allergen. The following interesting information from HealthCentersOnline ( ) is thought to be of interest. We are focusing on Ragweed in this section.

RAGWEED

Aug 11 (HealthCentersOnline) - “Experts are warning people with ragweed allergies about the risks associated with oral allergy syndrome.

Ragweed is a weed that grows throughout the United States. The plant produces highly allergenic pollen, causing widespread cases of hay fever (allergic rhinitis) and asthma attacks. Ragweed pollens cause allergies when the pollen grains become airborne and lodge inside the mucous membranes that line an individual's nasal cavities. The result is symptoms such as sneezing, nasal congestion, watery eyes and itchy nose. Ragweed typically begins to bloom and release pollens around August 15.

As the start of ragweed season approaches, the American Academy of Allergy, Asthma & Immunology (AAAAI) is warning patients that consuming fresh fruits and vegetables can also trigger symptoms.

Plants that are members of the same family can create similar allergic reactions in an individual, a phenomenon known as cross-reactivity. Oral allergy syndrome (OAS) is a type of cross-reactivity in people highly sensitive to particular pollens, including ragweed. During the seasons that ragweed pollinates, patients may experience a rapid onset of itching in the mouth and throat and mild swelling after attempting to eat foods from the same plant family. In some cases, OAS triggers severe throat swelling or severe systemic allergic reactions (anaphylaxis), which can cause breathing difficulties and possibly death.

Individuals with ragweed allergies may experience the symptoms of OAS immediately after consuming foods such as:

• Bananas
• Cucumbers
• Melons
• Zucchini
• Sunflower seeds
• Chamomile tea
• Echinacea”
