Eucalyptus oil is derived from the leaves of the eucalyptus tree, which is native to Australia but is now grown in many parts of the world. The oil has been used for centuries by Indigenous Australians for its medicinal properties.   Eucalyptus oil has a strong, fresh, and invigorating aroma that is often used in aromatherapy and as a natural insect repellent. The oil contains compounds called cineole and terpenes, which have anti-inflammatory and antiseptic properties. Eucalyptus oil is also commonly used in cleaning products and as a flavouring agent in food and beverages.  Eucalyptus oil is commonly used in Ayurvedic medicine for its cooling and calming properties. It is often used to treat respiratory issues, muscle and joint pain, and skin conditions.
