Definition
Allergenic describes a substance or condition that can cause an allergic reaction in a sensitive individual. Think of it as a trigger that sets off your body's defense system unnecessarily. Common allergens include pollen, pet dander, certain foods, and insect stings. The immune system mistakenly identifies the allergen as a threat, leading to symptoms like sneezing, itching, or even more severe reactions. It's all about an overreaction to something that's usually harmless to most people.
