Traditional Benefits
Native to Australia and long used in Aboriginal medicine, eucalyptus leaf has traditionally been brewed as a tea or applied as a steam inhalation to clear the lungs, ease fever, and purify the air. It is a staple herb for respiratory complaints and immune defense in traditional Western and folk medicine.

A Natural Allergy Ally
Eucalyptus leaf helps open airways, clear mucus, and reduce sinus inflammation—making it a powerful ally during allergy season or when facing respiratory irritation from dust, pollen, or pollution.

A Herb for Seasonal Support
Especially useful in colder months or during times of seasonal colds and flus, eucalyptus supports clear breathing, eases congestion, and invigorates the body when energy is low.

How It Works
Rich in eucalyptol (cineole), eucalyptus leaf helps loosen phlegm, reduce inflammation in the respiratory tract, and fight microbial overgrowth. Its cooling, penetrating nature helps open blocked nasal passages and ease muscle aches when used externally or as a tea or steam.

Best Ways to Use It
Tinctures/Extracts: Used in low doses for respiratory support or immune defense.
Herbal teas: Brew with other respiratory herbs like thyme, peppermint, or licorice to relieve congestion and soothe coughs.
Topical applications: Infused in oils, salves, or used in steam inhalation to support sinus relief, sore muscles, or chest congestion.

Fun Fact
Koalas eat eucalyptus leaves as their primary diet, thanks to their ability to detoxify the strong essential oils—though these same oils are what make eucalyptus so effective for humans externally.

A Herb for Modern Use
Eucalyptus leaf is a go-to herb for stuffy sinuses, chest colds, and immune support. From herbal steams to bath blends, it clears the airways and the mind—helping you breathe easy and stay resilient through seasonal shifts.
