Studies
• Antibacterial Activity of Three Medicinal Plants: Eucalyptus Globulus, Aristolochial Latas and Vitex Negundo against Enteric Pathogens: The medicinal plants tested showed varying degrees of antibacterial activity with the maximum zone of inhibition obtained with E. globulus.
• Antihyperglycemic Actions of Eucalyptus globulus (Eucalyptus) are Associated with Pancreatic and Extra-Pancreatic Effects in Mice: The study suggests that E. globulus may be an effective antihyperglycemic dietary supplement for the treatment of diabetes. The study also showed pancreatic protection or regeneration following exposure to streptozotocin.
• Antibacterial activity of leaf essential oils of Eucalyptus globulus and Eucalyptus camaldulensis: Study suggested the potential usefulness of the two Eucalyptus species as a micobiostatis, antiseptic or as a disinfectant agent.
