Is the American Curly Horse HYPOALLERGENIC?

Scientists have been styduying the American Curly Horse for over a decade. As they finish their studies, they release their study results. One of their latest discoveries, is that the claims about the American Curly Horse being hypoallergenic are, in fact, true!!


Here is the overview of the latest study results by Dr. Wolfgang Mitlehener:

Author Information



To test the hypothesis that so called hypoallergenic horses (Curly horses) allow horse allergic riders to ride again, we investigated 40 horse allergic riders in a period of 37 moths. Methods: We tested these patients (pts) by skin prick test (SPT) with different non-curly and Curly horses and studied the riding hours and horse brushing by measurements of peak expiratory flow (PEF) and Tiffeneau tests (FEV1) as well as peak nasal inspiratory flow (PNIF) over 23 months. The results in 37/40 pts. showed no relevant eactions of the lower airways or nasal flow. Only in 3/40 patients an initial significant fall of FEV1 was observed, reversed by a single inhalation of salbutamol and not repeated despite further riding contact. In contrast to other allergic events (e.g. baker's asthma) a further and regular contact with these horses abolished the mild allergic reactions of the start period of contact. THis may be due to hypoallergenic properties of these horses whose test material produces weaker reactions in the SPT than that of normal horses. After a period of three years, a loss of reactivity to normal horses could be confirmed in some of the riders. Conclusion: the tested purebreed Curly horses may be a suitable alternative for horse allergic riders if the methodological precautions of this study are followed.
