Oral Allergy Syndrome (OAS) is a mild food allergy causing mouth itching from cross-reactive proteins in raw fruits and pollens. Cooking often eliminates reactions.
This blog post covers the following topics:
Imagine biting into a juicy peach, only to experience tingling and itching in your mouth. This could be Oral Allergy Syndrome (OAS), also known as pollen-food syndrome. OAS is a food allergy stemming from cross-reactivity between proteins in certain raw fruits, vegetables, and nuts, and pollen allergens. It's generally mild, with symptoms usually limited to the mouth, lips, and throat.
Stone fruits—peaches, plums, cherries, apricots, and nectarines—are common OAS triggers. These fruits contain proteins similar to those in pollens, like birch pollen. This similarity, called cross-reactivity, means if you're allergic to birch pollen, your immune system might react to the proteins in a peach. Cooking often denatures these proteins, lessening or eliminating the reaction. A raw peach might cause a reaction, but a baked peach cobbler might be fine.
Understanding OAS is crucial for several reasons:

Sublingual immunotherapy (SLIT) is a convenient, less invasive alternative to allergy shots. Instead of injections, SLIT involves placing a small allergen dose under the tongue (tablet or liquid). This home-administered method gradually desensitizes the immune system, reducing reaction severity over time.
SLIT works through oral mucosa immune cells. When an allergen is introduced sublingually, these cells (including dendritic cells) capture and process it, initiating immune tolerance. This involves:
SLIT retrains the immune system, reducing reaction intensity and frequency. Improvements typically appear over months.
Several allergy management options exist. SLIT differs in key ways:
| Treatment | Administration | Benefits | Drawbacks |
|---|---|---|---|
| SLIT (Sublingual Immunotherapy) | Under the tongue (tablets or liquid) | Convenient, home-administered, lower risk of severe reactions | Daily adherence needed, may not work for all allergens, slower onset |
| Allergy Shots (Subcutaneous Immunotherapy) | Injections by a healthcare professional | Effective for many allergens, potential for long-term remission | Frequent doctor visits, higher risk of systemic reactions, can be painful |
| Antihistamines | Oral medication | Quick symptom relief, readily available | Treats symptoms only, not the underlying cause, can cause drowsiness |
| Nasal Corticosteroids | Nasal spray | Reduces nasal inflammation, effective for congestion | May cause nasal irritation, nosebleeds, doesn't address the underlying cause |
The best treatment depends on individual needs and allergens. SLIT offers a convenient, at-home option with a lower risk of systemic reactions.
While research on SLIT specifically for stone fruit allergies is limited, studies on SLIT for other food and pollen allergies offer insights. These studies often show significant symptom reduction and improved allergen tolerance after SLIT. Research on pollen-related food allergies suggests promising results for managing stone fruit OAS through targeted SLIT.
SLIT's impact is best seen through patient experiences. Though stone fruit OAS-specific testimonials are anecdotal, patients with similar pollen-related food allergies often report improved quality of life after SLIT, including:
These positive outcomes highlight SLIT's potential to alleviate stone fruit OAS.

Managing stone fruit OAS starts with identifying triggers. Keep a food diary noting every stone fruit eaten and any symptoms. This helps pinpoint specific triggers. Meticulous avoidance is key—read labels carefully, inform servers about your allergy when eating out, and prevent cross-contamination.
The allergenic proteins in many fruits are heat-labile, breaking down with heat. Many with stone fruit OAS can enjoy cooked fruits. Experiment with cooking methods (poaching, baking, grilling) to find what works. Introduce cooked fruits slowly to monitor tolerance.
While OAS symptoms are usually mild, be prepared for severe reactions. Anaphylaxis, though rare, can occur. Know the signs (difficulty breathing, throat swelling, hives, dizziness, rapid heartbeat) and seek immediate medical attention if they occur. If you have a history of severe reactions, your doctor may prescribe an epinephrine auto-injector. Wear a medical alert bracelet.
Managing stone fruit OAS involves understanding triggers, taking precautions, and being prepared for reactions.
OAS can impact quality of life. While avoidance is crucial, SLIT addresses the underlying pollen allergy. Consult a qualified allergist to determine if SLIT is right for you. The allergist will conduct a thorough evaluation including allergy history review, testing, and a discussion of your lifestyle and needs.
SLIT treatment involves:
SLIT is a long-term treatment (3-5 years). Consistency is key.
Monitor progress through symptom tracking, food challenges (under allergist supervision), and periodic allergy testing. Your allergist may adjust your SLIT dosage or plan based on your progress.
