The leaves are the part of the tree that is used. They contains essential oil (1,8-cineole or eucalyptol, globulol, trans-pinocarveol, α-terpineol, cymen, α-pinene and β-pinene), hydrocyanic acid, tannins, terpenes, flavonoids and phenolic acids (phytotherapy.net).

At the date of the last update, the authors did not find any published data on its excretion in breast milk.
Various components of eucalyptus are excreted in breast milk and confer a characteristic odor and flavor to milk that could be perceived by the infant. (Debong 2020, Spahn 2019, Kirsch 2012)
Eucalyptol has no suppressive activity on breast epithelial cells. (Suzuki 2020)
Eucalyptol is neurotoxic and convulsive (Burkhard 1999). Overdosing of essential oil can cause severe neurological depression in adults and children. (Hale, Waldman 2011, Halicioglu 2011, Darben 1998, Webb 1993, Patel 1980)
The European Medicines Agency contraindicated it in children with a history of seizures and in children under 30 months and did not recommend it in children under 4 years and during breastfeeding. (EMA 2014)
Due to the toxicity of its essential oil, it is not prudent to use it during breastfeeding outside of occasional and moderate use.
Topical use is compatible with breast-feeding as long as it is not applied to the breast.
