Results Flare, wheal, and itch Following histamine prick, a substantial local reaction was
observed. The mean diameter of flares reached 24 mm and showed a maximum about 5 min
after prick. Mean wheal diameters increased continuously up to 6 mm at the end of the
session. After saline prick, the flare was considerably smaller and a wheal was never
detected. Accordingly, ratings of itch intensity and unpleasantness were much higher after
histamine than after the saline prick (see Fig 1).
