I'm just learning about aromatherapy atm.
Rosmarinus officinalis ct *camphor (1)
Rosmarinus officinalis ct cineole (2)
Rosmarinus officinalis ct verbenone (3)
Book I have ("Aromatherapy and A-Z" by Patricia Davis) states:
"Rosemary oil may be distilled from the flowering tips or the leaves, though an inferior oil is sometimes extracted from the whole plant".
"Like Thyme, this is a plant with quite variable chemistry, but typical examples would include camphor (1), borneol, pinene and cineole (2)...Some samples or wild Rosemary...there is a chemotype with mainly verbenone (3)"
So its referring to the chemical composition of the plant. All are Rosemary and all have the stimulating effect on the central nervous system.
It all suggests that the "verbenone variety is most effective for clearing catarrh, it is less stimulating than the others so is suitable to use in the evening".
Hope that helps.
