Cajeput essential oil is made from distilled leaves and branches of cajeput trees. Cajeput also goes by the names of cajuput, kajuput, melaleuca cajuputi, and minyak kayu putih. The oil is primarily known for its antiseptic and analgesic qualities. It’s also considered an anti-inflammatory, which is sometimes used to help treat minor skin wounds, colds, and inflammatory skin diseases. Despite its use as a natural product, cajeput oil can be as strong as traditional medication.
