Histamine is a chemical your own body makes. When you have an allergy — to , dust, some foods, or a sting — certain cells let out histamine, and that is a big reason you , sneeze, swell, or get a runny nose. on a medicine box means a drug that blocks this chemical, so those feelings calm down. Though actually histamine is not only an allergy chemical. It also helps the stomach make acid for food, so it has quiet jobs on ordinary days, not only on hay-fever days. You do not buy histamine in a shop. It is already inside you. Doctors and medicine labels use the word; everyday talk often just says allergy. The name is built from histidine, a piece of protein, plus amine, a kind of chemical piece.
組成From hist(idine) + -amine. Histidine is a building piece of protein; -amine is the chemical piece.
