camphor oil
C2Technical/Specialised
Definition
Meaning
A volatile essential oil distilled from the wood of the camphor tree, used for its medicinal and aromatic properties.
The term can also refer to a specific fraction of crude camphor oil (like white, brown, or blue camphor oil) with distinct properties, or to a synthetic oil with a similar scent and chemical composition. It is a central ingredient in traditional remedies, insecticides, and industrial applications like plastics manufacturing.

Semantic Notes
Refers specifically to the extracted oil, not to solid camphor. Its primary associations are medicinal, aromatic, and industrial. In everyday contexts, people are more likely to refer to 'camphor' (the solid) or products like 'camphorated oil' (a liniment).

Frequently Asked Questions
Not exactly. 'Camphor oil' typically refers to the essential oil distilled from the tree. 'Camphorated oil' is usually a preparation where solid camphor is dissolved in a carrier oil (like olive oil) to make a liniment.
No, it is highly concentrated and can cause skin irritation or systemic toxicity. It must be significantly diluted in a carrier oil or used as an ingredient in a prepared product.
It has a very strong, penetrating, medicinal, and woody aroma that is sharp, cooling, and somewhat mothball-like.
Products containing camphor (including oils) are generally not recommended for young children, especially infants, due to the risk of serious side effects like seizures if ingested or absorbed through the skin in high concentrations.
