Essential oils ; 29 compounds isolated that correspond with those found in P. colorata ( Briggs et al, 1975).

The name 'horopito' refers to both P.axillaris and the closely related P. colorata. The medicinal notes probably refer to both species. Horopito is perhaps more commonly used these days for P. colorata - which has blotchy coloured leaves,  is more peppery and is more easily recognised.  Both species hybridise.
