Antifungal activity of the bark and leaf oils of Cinnamomum verum J.S. Presl. alone and in combination against Various Fungi

The leaf and bark oils of Cinnamomum verum J.S. Presl. were examined for their antifungal activity against 6 dermatophytes (Trichophyton rubrum, T. mentagrophytes, T. tonsurans, Microsporum canis, M. gypseum and M. audouini), one filamentous fungi(Aspergillus fumigatus) and 5 strains of yeasts (Can...
