Eucalyptus is a popular ingredient used in ancient systems of medicine all over the world, especially in China, India, Greece, and Europe. Leaves of the evergreen eucalyptus tree that is native to Australia are used to treat several conditions due to its antioxidant and antiseptic properties.
The leaves are good for overall health since they contain flavonoids, the largest group of phytonutrients that are filled with antioxidants. They also contain tannins, which are known for antimicrobial activities.
The flavonoid compounds found in the leaves are quercetin, phloretin, catechins, luteolin, and kaempferol. All of which prevent cancer, heart disease, and dementia.
The best way to derive the benefits of eucalyptus leaves, not in oil form, is by making use of one dry leaf to prepare tea.
