Camphor essential oil, apart from having a cool, penetrating and lasting aroma, has many medicinal properties as well. Camphor essential oil is an effective stimulant, which boosts the activity of the circulatory system, metabolism digestion secretion, and excretion. Camphor oil is an excellent disinfectant, insecticide, and germicide. It can be added to drinking water to disinfect it, particularly during the summer and in rainy seasons when there is a higher chance of water becoming infected. An open bottle or container of camphor oil, or burning a piece of cloth soaked in camphor oil, drives away insects and kills germs. A drop or two of camphor oil, mixed with plenty of food grains helps in keeping them safe from insects.
