Eucalyptus leaves have demonstrated, since 1865, when the first eucalyptus trees were introduced in Peru from Oceania, their incredible properties to treat respiratory ailments. From there, its planting spread rapidly in the Mantaro Valley in Junin and became part of traditional medicine in the Peruvian Andes to treat flu, asthma, tonsillitis, bronchitis, sinusitis, congestion and as an expectorant.
Of the 800 species that exist in Peru there are at least 10, but the best known is Eucalyptus globulus. In second and third place are Eucalyptus urograndis and Eucalyptus citriodorus. All these species are used for medicinal purposes.
