Eucalyptus honey

Jarrah honey in particular demonstrates significant antibacterial effects against both Gram-positive and Gram-negative bacteria, with minimum inhibitory concentrations (MICs) ranging from 6.7% to 28.0% (w/v).

Application of jarrah honey to existing biofilms decreased bacterial metabolic activity and viability, indicating potential for treating biofilm-associated infections in wound care.

Jarrah honey (Eucalyptus marginata) is effective in inhibiting dermatophyte fungi responsible for skin infections such as athlete's foot and ringworm.

Scanning electron microscopy showed structural deformities in mature T. rubrum hyphae, including bulging and collapsed regions, after treatment with the jarrah honey.

Despite the evident structural damage to fungal cells, internal oxidative stress was not detected, suggesting that Jarrah honey's antifungal effects are primarily surface-active, possibly due to the localized production of hydrogen peroxide and other bioactive compounds.
