Seasonal allergies, from the perspective of traditional Chinese medicine, are not viewed as an isolated immune overreaction or a simple sensitivity to pollen, dust, or mold. Instead, they are understood as a reflection of the body’s relationship with its environment and the balance—or imbalance—of internal systems that govern protection, circulation, and adaptation to seasonal change. Where modern medicine often asks, “What is the allergen?” Chinese medicine asks a different question: “Why is this person vulnerable right now?”
