Figure 3From: Aluminum sulfate significantly reduces the skin test response to common allergens in sensitized patientsAluminum sulfate does not block histamine. Skin reactions at 15 min are shown in panel (A). Skin reactions at 30 min are shown in panel (B). Within panels A and B, skin prick responses are shown to: saline (1), histamine (2), 0.9% AS (3), 9.0% AS (4), 0.9% AS + histamine (1.8 mg/ml) mixed at 1:10 (AS:histamine) (5), and 9.0% AS + histamine (1.8 mg/ml) mixed at 1:10 (AS:histamine) (6). Skin reaction to 0.1 cc AS ID at 15 min is shown in panel (C) (site 7). Skin reaction 15 min following overlay of site 7 in panel C with histamine (1.8 mg/ml) is shown in panel (D). Notice that AS did not inhibit the histamine induced skin reaction.Back to article page
