Document Summary

Allergy: an adverse reaction to harmless material, typically an immune reaction to something harmless. Immune system responds to something: epitopes of molecules from pathogens. Immune system remembers that material (via memory cells: subsequent exposure produces the reaction, protection from pathogens, allergy to harmless material. Immune reactions happen at the site of contact; like chemicals in poison ivy or oak generate an immune reaction in that area: urushiol produces the reaction. Latex from rubber tree sap: contains small amounts of tree proteins, e. g. latex gloves and condoms. It"s likely it"s the protein causing the reaction and not the rubber: for people allergic to latex, nitrile gloves are available; also sell cotton gloves that go underneath latex (pretty comfy apparently) ); so nickel allergies are common because they get added to a lot of products to make them tougher and stronger for decently cheap; so it"s a trace material in all different kinds of metals.
