Résumé |
The oleoresin of Mauria puberula (MP), a poisonous species of the Anacardiaceae that is indigenous to the Venezuelan Andes, was shown to cause both primary irritant dermatitis and allergic contact dermatitis in guinea pigs and humans. Cross-sensitization reactions were found in persons with known allergy to Toxicodendron spp. or Lithraea caustica and in guinea pigs sensitized to 3-n-pentadecylcatechol. These results suggest that the active principles of MP are probably chemically related to, but not identical to, those of Toxicodendron.
