Histamine Restricted Diet
The outcome of a 4 week histamine restricted diet with 44 individuals suffering from 'idiopathic' urticaria, angioedema and pruritus found that 61.4% reported significant improvement and 18.2% reported some improvement.
Other symptoms such as migraines and panic attacks were also alleviated for some of the participants. As the study was not of the type favoured by scientists (i.e. double blind) the authors are reluctant to draw any conclusions other than that the results suggest that this type of restricted diet may be of benefit in some cases.
