Eucalyptus (Eucalyptus globulus Myrtaceae)

Other Names: Blue Eucalyptus, Rounded Eucalyptus, Southern Blue Gum

Eucalyptus, native to Australia, is a large tree with smooth gray-blue bark, typically growing 30 to 100 feet tall. The German botanist Ferdinand von Müller was the first European to recognize the healing properties of the fragrant oil derived from its narrow, leathery leaves, which grow on branches older than five years.

Parts for Use

Leaves

1. Fragrant leaves are harvested from older branches, typically in summer.
2. Leaves are dried or distilled for their essential oil.
3. Dried leaves are ground into powder or used for infusions and tinctures, while the oil is used in syrups, balms, and ointments.

Ingredients

The leaves contain flavonoids and a significant amount of essential oil rich in cineole and eucalyptol.

Use in Treatment

Numerous studies have demonstrated that eucalyptus has antibacterial, antifungal, and antiviral properties. Its antiseptic action, combined with its ability to improve blood oxygen saturation, is attributed to eucalyptol in the essential oil. This makes eucalyptus effective for treating respiratory conditions such as coughs and colds. Its antiseptic properties also make it useful for cuts, wounds, and burns. The flavonoids in eucalyptus help lower blood sugar, as confirmed by clinical trials. Additionally, eucalyptus can enhance blood flow, which aids in relieving muscle pain.

Cultivation

Eucalyptus prefers a warm climate but can tolerate temperatures as low as minus fifteen degrees Celsius. It is grown from seeds in a sunny location with well-drained, nutrient-rich, acidic to neutral soil.
