<p>OAS or Oral Allergy Syndrome is basically a reaction you get when you eat raw fruits and vegetables due to your allergies related to pollen. So yeah, basically I just ate an apple with peanut butter, and my bottom lip started swelling intensely. This seems to always be happening when I eat raw fruits, but when they’re cooked, they taste great and all of those allergens are cooked out.</p>
<p>Has anyone else experienced this problem or thinks they have this syndrome?</p>
