I thought this article would be useful for aromatherapists to read, since
we tend to be somewhat deprived of state-of-the-art progress reports on
safety matters! To help with interpretation of any unfamiliar immunological
terms and acronyms, I have added keys to these, following the article
end. Thanks to David Basketter, Marion Roberts and the IFSCC editorial
board for allowing this to happen!

Antigen: any substance (chemicals, pollen) that causes the immune system
produce antibodies against it.
Buehler Test: an occluded application test using the guinea pig (Buehler
1965) to predict sensitisation. Now superseded by the LLNA Test which
animal welfare advantages.
Cytokines: small secreted proteins which mediate and regulate immunity,
Dendritic cells: an antigen presenting immune cell which functions to
the immune response by activating lymphocytes and stimulating the
production of cytokines.
Haptens: a small molecule that reacts with a specific antibody but cannot
induce the formation of antibodies unless bound to a carrier protein or
large antigenic molecule.
Magnusson & Kligman Maximisation Test: (Magnusson & Kligman 1970)
predictive test based on induction by patch test or intradermal injection.
