Eucalyptus is antibacterial, anti inflammatory and anti microbial making it a versatile plant. In lozenges or as an inhalant, eucalyptus is great at fighting colds and respiratory issues by acting as a decongestant and expectorant. In a gargle, eucalyptus can soothe a sore throat and relieve symptoms from sinusitis in addition to fighting tooth decay and oral bacteria. Topically eucalyptus can treat fungal infections and soothe sore muscles and joints from injury, overuse, or arthritis. The cool, refreshing scent of eucalyptus makes it ideal for aromatherapy to reduce stress and encourage mental clarity by increasing blood flow to the brain. Eucalyptus should never be taken orally (it is poisonous) or applied near the eyes. Eucalyptus can interact with medications so always check with your doctor or a clinical herbalist.
