[16] Ascaridole, camphor and eucalyptol are monoterpenes that have pharmaceutical use. [18] [19]

It would be like saying that citronella oil is the same citronellal - which they are not. So I have seperated "Eucalyptus oil" and "Eucalyptol" into seperate ...

Besides terpin hydrate, other expectorants lacking evidence of efficacy include ammonium chloride, beechwood creosote, benzoin preparations, camphor, eucalyptol/eucalyptus oil, iodines, ipecac syrup, menthol/peppermint oil, pine tar preparations, potassium guaiacolsulfonate, sodium citrate, squill preparations, tolu and turpentine oil.
