A special extract from the leaves, flowers and/or fruit of Crataegus monogyna or Crataegus oxyacantha is produced by extraction with a prior art extraction agent, making an aqueous solution of the extract, heating the aqueous solution to form high-molecular condensable flavanes and filtering the components thrown down on heating. The extract thus produced is particularly pharmaceutically effective and is suitable in particular of the treatment of allergic diseases and even non-allergic asthma.

L'invention concerne un extrait spécial de feuilles, de fleurs et/ou de fruits de Crataegus monogyna ou de Crataegus oxyacantha, dont la préparation comprend les étapes suivantes: extraction à l'aide d'un agent d'extraction classique, préparation d'une solution aqueuse de l'extrait, chauffage de la solution aqueuse pour obtenir des flavanes condensables à très haute masse moléculaire, filtration des constituants séparés au cours du chauffage. L'extrait ainsi préparé présente une efficacité pharmaceutique particulière et s'utilise notamment pour le traitement de maladies allergiques, ainsi que pour celui de l'asthme d'origine non allergique.
