Eighteen plant extracts from nine traditional Mexican medicinal plants were tested for antifungal activity against two dermatophyte fungal species (Trichophyton mentagrophytes and Trichophyton rubrum), one non-dermatophyte (Aspergillus niger), and one yeast (Candida albicans). The strongest effect was manifested by the hexane extracts from Eupatorium aschenbornianum and Sedum oxypetalum, as well as the methanol extracts from Lysiloma acapulcensis and Annona cherimolia.
