Interesting. As far as I know, such traits are genetical and are inherited. Am I right on that?
insect stings, and medications are common causes of severe reactions. Their development is due to both genetic and environmental factors. The underlying mechanism involves immunoglobulin E antibodies (IgE), part of the body's immune system, binding to an allergen and then to a receptor on mast cells or basophils where it triggers the release of inflammatory chemicals such as histamine.

PPD was voted Allergen of the Year in 2006 by the American Contact Dermatitis Society. Henna
