Stone fruit allergy

The compounds present in stone fruit can trigger allergic reactions in some right after eating peaches, cherries or plums.

Once the immune system erroneously sends histamine and other chemicals to counteract these foods, it triggers the itchiness in the lining of the mouth and throat. Take note that allergic reactions to plums, cherries and similar fruits often produce severe itching.


Swollen eyelids, lips and face can also indicate stone fruit allergy. The presence of histamine induces the inflammatory response characterized by swelling of the tongue and throat aside from the itchiness. The inflammation can also affect the skin particularly after direct exposure to the fruit through handling, resulting to hives or rash that has elevated welts. Redness, warmth, pain and tenderness can also accompany the swelling.

Digestive symptoms

Once the allergens invade the digestive tract, the symptoms include abdominal pain, nausea, vomiting, abdominal cramping and diarrhea. Unless the individual is aware of his/her sensitivity to particular fruits, he/she might mistake these physical indications for food poisoning by bacteria or toxic contamination. In reality, the individual might be experiencing an allergic reaction to the low amount of cyanogenic compounds present in Prunus fruits but only allergy testing can determine the precise source of the illness.

Respiratory symptoms

Once the inflammatory response instigated by the presence of histamine in the blood causes internal swelling, the individual can suffer from difficulty breathing. The inflamed mucous membranes can cause stuffed or runny nose as well as difficulty swallowing. These symptoms can progress to airway obstruction and shortness of breath. The individual is advised to pay close attention to the respiratory symptoms which can be limited or can quickly worsen.

What is anaphylaxis?

Gemerally, a severe allergic reaction to stone fruit is called as anaphylaxis which includes cardiovascular issues aside from the breathing issues. There is an abrupt drop in the blood pressure which leads to lightheadedness and fainting along with the possibility of respiratory or cardiac arrest. Consequently, this requires immediate medical care or call for emergency assistance right away.
