Support - looking into the addition of “(+histamines),” the MilesDown pdf includes histamine with an arrow up - which seems to indicate that eosinophils release or increase histamine levels; upon further research (see reference below), “eosinophils can cause activation and consequent histamine release of already challenged mast cells” so I’ve edited to indicate histamines are activated/released by eosinophils
