Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Japanese camphor (Cinnamomum camphora) has a documented history of use as an insect repellent, and its use is supported by both traditional practices and scientific studies. Camphor has been employed in East Asia for centuries to deter insects, particularly in the form of camphor blocks or balls placed in closets and storage to protect textiles from moths and other pests. The scientific basis for camphor’s insect-repellent properties lies in its volatile compounds. Laboratory studies have demonstrated that camphor vapor can repel certain insects, including mosquitoes and moths. For instance, research has shown reduced mosquito landings and feeding in environments where camphor is present compared to control environments. The mechanism is thought to involve interference with the insects’ olfactory receptors, making it harder for them to locate hosts or suitable environments.

However, while in vitro and small-scale studies confirm some efficacy, there is limited large-scale field research or comparative trials with standard synthetic repellents such as DEET. Thus, while the tradition is validated by some scientific evidence, the overall strength of the evidence is moderate (rated 3/5). More rigorous, standardized studies would be necessary to fully confirm camphor’s efficacy, optimal concentrations, and safety profiles for widespread use as an insect repellent.
