Antifungal activity of essential oils and their volatile constituents against respiratory tract pathogens causing Aspergilloma and Aspergillosis by gaseous contact
Journal Title: Journal of Applied and Natural Science - Year 2012, Vol 4, Issue 1
Abstract
Aspergillosis is an acute chronic and rapidly fatal disease which is not contagious. Invasive Aspergillosisis often found in severely immuno-suppressed patients, and is characterized by invasion of blood vessels which can result into dissemination to other organs. Aspergilloma is a fungal ball that develops in previous cavitary lung lesions. Essential oils and their volatile constituents have been used as antifungal, anti-infectious and antimicrobial agents. Inhalation of vapours of the essential oils kill invaders attached to the inner respiratory lining and work synergistically with the body defences. In this study, 16 essential oils were used against Aspergillus niger and A. fumigatus of which about 14 oils proved to be effective. Results showed that the most effective oils against both Aspergillus species were found to be of Cinnamomum zeylanicum (Cinnamon), Syzygium aromaticum (Clove), Carum carvi (Caraway), Cymbopogon citrates (Lemongrass), Foeniculum vulgare (Fennel) and Myristica fragrans (Nutmeg). Moderately effective oils were of Gaultheria procumbens (Wintergreen), Pinus palustris (Turpentine), Sesamum indicum (Sesame), Trachyspermum ammi (Ajowain) and Origanum vulgare (Oregano). The oils of Lavandula augustifolia (Lavender), Elletaria cardamomum (Cardamon) and Cymbopogon nardus (Citronella) showed minimum activity. Azadirachta indica (Neem) and Linum usitatissimum (Linseed) showed no activity giving no inhibition zones.
