Cajeput oil is widely used in aromatherapy for its refreshing and invigorating scent, which helps alleviate stress and promote mental clarity. It is also applied topically as a natural remedy to relieve muscle pain, joint discomfort, and inflammation due to its analgesic and anti-inflammatory properties. In respiratory care, it is often inhaled or used in steam treatments to ease symptoms of colds, coughs, and sinus congestion. Additionally, cajeput oil serves as an antiseptic for minor cuts, wounds, and skin infections, helping to prevent bacterial growth. It is sometimes incorporated into oral care products like mouthwashes for its antimicrobial effects and ability to freshen breath.
