Abstract

Two essential oils derived from Lavandula angustifolia and Lavandula × intermedia were investigated for any antiparasitic activity against the human protozoal pathogens Giardia duodenalis and Trichomonas vaginalis and the fish pathogen Hexamita inflata: all of which have significant infection and economic impacts. The study has demonstrated that low (≤1%) concentrations of L. angustifolia and L. × intermedia oil can completely eliminate T. vaginalis, G. duodenalis and H. inflata in vitro. At 0.1% concentration, L. angustifolia oil was found to be slightly more effective than L × intermedia oil against G. duodenalis and H. inflata. The potential applications are discussed.
