What does camphol mean?
Camphol is a crystalline bicyclic terpene alcohol with the formula C10H18O, produced by the chemical reduction of camphor. It exists in two stereoisomeric forms: the naturally occurring dextrorotatory variety known as borneol, found in the resin of trees such as Dryobalanops aromatica, and a synthetic racemic form known as isoborneol. The name derives from 'camphor' plus the '-ol' ending characteristic of alcohols, marking it as the reduced, alcohol-bearing counterpart of camphor itself. Although once a familiar entry in chemistry and pharmacology texts, camphol has largely fallen out of common use, and contemporary chemists typically refer to borneol or isoborneol directly. It remains a useful example of how a single carbon framework — the bornane skeleton — can yield distinct compounds depending on whether the functional group is a ketone or an alcohol.
nounA crystalline bicyclic terpene alcohol, C10H18O, obtained by the reduction of camphor and occurring in two stereoisomeric forms (borneol and isoborneol); it is closely associated with camphor in both source and chemistry.
- A crystalline bicyclic terpene alcohol, C10H18O, obtained by reducing camphor, existing as borneol and isoborneol stereoisomers.
- Specifically, dextrorotatory borneol derived from natural camphor sources such as Dryobalanops aromatica (Bornean camphor).
"The chemist reduced the camphor to camphol and confirmed the product's melting point."
"When camphor is reduced with sodium in ethanol, the principal product is camphol."
"Older pharmacological texts list camphol among the constituents distilled from Bornean camphor oil."
Rarely pluralised in practice; when referring to the two stereoisomers collectively, writers more often say 'the camphols' or simply name borneol and isoborneol separately.
"Both stereoisomeric camphols were isolated from the reaction mixture."
Camphol is essentially camphor that took on a hydrogen or two — same carbon skeleton, but chemically a different compound entirely.

Etymology of camphol
Camphol was formed in the nineteenth century from 'camphor', which entered English through Latin 'camphora' from Arabic kāfūr, ultimately traced to Malay kapur barus ('Barus chalk'), referring to the camphor-producing trees of Sumatra and Borneo. The '-ol' suffix marks it as an alcohol, following the systematic nomenclature adopted by organic chemists for reduced forms of carbonyl compounds.
How camphol is actually used
A technical term of organic chemistry, now largely historical; modern literature usually refers directly to borneol or isoborneol rather than using the name camphol.
Easily confused with camphol
Camphor is a ketone (C10H16O) with a penetrating medicinal odour used as a plasticiser and moth repellent, whereas camphol is its corresponding reduced alcohol form.
