If you look at a microscopic image of pollen you will see this spiky ball. The spiky ball is inhaled through your nose or mouth and gets stuck in your mucous membranes. The mucous membranes in our breathing passages contain mast cells which are a part of our immune system. These mast cells contain histamines. Histamines are what cause “allergic reactions” and allergy symptoms.This by far is the most simple of solutions. A simple saline rinse will flush the pollen from your nasal passages and remove the offending pollen grain. You can use a saline nasal spray or a netti pot. Netti pots, in my experience, are much more effective at getting the foreign particles out.
