Native to the swampy areas of northeastern Australia, tea tree was long known to Aboriginal peoples, who crushed its leaves to breathe in their scent or applied them to the skin. Introduced to the West in the twentieth century under the name "tea tree," it owes its renown to its essential oil, reputed for its purifying properties.
Fresh crushed leaves or the essential oil were traditionally inhaled to clear the airways during seasonal chills.
Applied locally and diluted, tea tree essential oil was used by Aboriginal Australians to soothe minor skin irritations and superficial wounds.
Recognized for its characteristic scent and purifying properties, it went into traditional preparations for scalp and skin hygiene.
Carefully diluted, it could be used as a traditional mouth rinse for freshness and oral hygiene, never swallowed.
Never ingest tea tree essential oil, even diluted: it is toxic when taken orally, particularly for children. Always dilute the essential oil in a vegetable oil before skin application, or risk irritation or allergic reactions. Avoid any use during pregnancy or breastfeeding, and in young children, without the advice of a health professional. Perform a preliminary skin test and consult a professional in case of doubt, ongoing medication, or sensitive skin.
