Natrapel Lemon Eucalyptus is made with oil of lemon eucalyptus. The oil of lemon eucalyptus used in Natrapel is a non-GMO substance made solely from eucalyptus citriodora oil. This carbon-negative process starts with ethically and sustainably sourced lemon eucalyptus trees (also called eucalyptus citriodora trees). The trees are grown on small plantations and tended by hand. Leaves and twigs are selectively cut to maintain the health of the tree and distilled by passing steam through a holding vessel. As the steam cools, the oil is separated. Waste leaves are removed and used as fuel or to maintain the health of the soil. The resulting essential oil is then modified through a simple conversion process to transform the high cintronellal content into PMD, the repelling agent found in oil of lemon eucalyptus.
