Eucalyptus plantations are often used to drain swampy areas due to their drying action on the soil. In the same way, taking into account the phytosociology of trees and plants, we can observe that the essential oil of eucalyptus radiata has a drying action on the humidity of our organism. Also, since ancient times, eucalyptus radiata leaf plasters have been used to "dry the lungs" when congestion was observed.
