It is widely used in food, pharmaceutical and as general household remedies for colds, throat irritation, pain, headache, etc.

Cajeput Oil Composition vs. Tea Tree Oil
Tea tree oils are extracted from Melaleuca alternifolia while cajeput is from Melaleuca Cajuputi or Melaleuca Leucadendra ( var. cajuputi).

Cajeput contains higher concentrations of 1,8 Cineole (Eucalyptol), limonene and alpha-Terpineol. Tea tree oil contains more Terpinen-4-ol and gamma-Terpinene. Therefore, cajeput has some properties similar to those found in Eucalyptus (from the Eucalyptol) and Lemon (from the limonene).
