A potent contact allergen of Phacelia (Hydrophyllaceae)

Abstract
The major contact allergen of P. crenulata (Hydrophyllaceae) was identified as geranylhydroquinone. A maximization test of geranylhydroquinone showed this to be a potent sensitizer comparable in degree to poison oak/ivy urushiol. Comparative patch testing on humans with urushiol established that the Phacelia allergen does not cross-react with poison oak or ivy.
