Eucalyptus oil, particularly Eucalyptus globulus, has been traditionally used for its antimicrobial properties, but there is also some scientific evidence supporting its use against fungal infections like Athlete’s Foot (tinea pedis). Several in vitro studies have demonstrated that eucalyptus oil exhibits antifungal activity against dermatophytes—the fungi responsible for Athlete’s Foot. For example, research published in the Journal of Ethnopharmacology (2002) and other studies have shown that eucalyptus oil can inhibit the growth of Trichophyton species, which are common causes of this condition. The primary active component, 1,8-cineole (eucalyptol), is thought to disrupt fungal cell membranes, leading to their death.

However, while laboratory studies are promising, there is a lack of robust clinical trials in humans directly evaluating the effectiveness of eucalyptus oil for treating Athlete’s Foot. Most evidence is derived from laboratory (in vitro) studies or animal models. Traditional use and anecdotal reports further support its application, often in combination with other essential oils, but this does not substitute for high-quality clinical evidence. As such, eucalyptus oil’s use for Athlete’s Foot is supported by preliminary scientific evidence but is not considered a first-line or fully validated treatment. It may be used as a complementary approach but should not replace established antifungal therapies without consulting a healthcare professional.
