What do produce allergies?

Any natural substance may cause allergies either through breathing (eg a grass pollen) or through ingestion (food or medication) or by contact by simply touching the allergen (animals and / or food).

The different types of allergens are classified as:

  • Pollens (grass, plants or trees) 
  • mites 
  • mushrooms 
  • Hymenoptera venoms 
  • Animals (dander or epithelia) 
  • food 
  • Drugs
