A frequent empirical observation is that cold-induced counter-irritation may attenuate itch. The aim of this randomized, single-blinded, exploratory study was to evaluate the counter-irritation effects of cold-stimulation and topical application of transient receptor potential TRPA1/M8-agonists (trans-cinnamaldehyde/L-menthol, respectively), on histamine-induced itch, wheals and neurogenic infl...

Toxicology and predictive irritancy studies in animal models can be readily retrieved from the literature (1-4), but methods for human testing are not as available. The rabbit is the species of choice for the preliminary evaluation of potential ocular irritation from toiletties, cosmetics and h...
