title: The effect of placebo and 'aggro' on the weal and flare response to histamine.
abstract: No change in the weal and flare response to histamine was found after placebo and 'aggro', the former given double-blind, the latter in a blind study. Placebo and 'aggro' actions may involve mechanisms other than the final response to mediators of inflammation.
