Description

Cajeput essential oil, often called White Tea Tree Oil or Cajeputi Oil, is distilled from the leaves and twigs of the Melaleuca cajuputi tree — a close botanical relative of tea tree (Melaleuca alternifolia) and niaouli (Melaleuca quinquenervia). Native to Southeast Asia and northern Australia, the cajeput tree thrives in warm, humid environments and produces an essential oil long valued for its fresh, camphorous aroma and purifying effects.

The oil’s scent is immediately recognizable: crisp, penetrating, and slightly fruity, combining the sharp clarity of eucalyptus with the softness of a light floral note. It’s often described as “cleaner and sweeter” than eucalyptus oil. This distinctive fragrance comes from its high content of 1,8-cineole (eucalyptol) and α-terpineol, compounds known for their respiratory, immune-supporting, and mentally clarifying benefits.

Historically, Cajeput oil was distilled and traded widely in Southeast Asia, where it became a household remedy for colds, sore muscles, and insect bites. Its name is derived from the Malay kayu putih, meaning “white wood.” The oil was prized in traditional medicine for its ability to clear congestion, ease pain, and purify the air — a reputation it still holds today.

In aromatherapy, Cajeput is recognized for its invigorating yet balancing energy. It helps clear mental fog, uplift the mood, and open the breath. Its fresh and slightly warming scent makes it ideal for blends supporting respiratory comfort, immune defense, and focus. Topically, when diluted, it offers a soothing warmth that can ease muscular tension and stimulate circulation.

Cajeput’s unique quality lies in its balance between clarity and calm. It stimulates without overwhelming, refreshes without harshness, and restores alertness while promoting steadiness. It’s a quintessential oil for restoring both physical energy and mental clarity — a breath of fresh air distilled from the tropical forests.

The cajeput tree has a long history in Malay and Indonesian traditional medicine. Its oil was used in poultices, massage balms, and steams for colds and fevers. Early European traders brought it westward, where it became a key ingredient in liniments and “cough balsams.” Today, it remains a staple in both Eastern and Western herbal traditions for its purifying, protective qualities.
