Why is eucalyptus oil antibacterial?

Eucalyptus oil is antibacterial primarily due to its high concentration of compounds such as eucalyptol (1,8-cineole), which possess antimicrobial properties. These compounds can disrupt the cell membranes of bacteria, inhibiting their growth and reproduction. Additionally, eucalyptus oil has been shown to enhance the immune response, further contributing to its antibacterial effects. Its natural properties make it a popular choice for use in various health and cleaning products.
