Oil of Geranium.
It is necessary to distinguish clearly between oil of true geranium distilled in Southern France and Algiers from species of Pelargonium; and Turkish oil of geranium, also known as Palmarosa oil, oil of geranium grass, oil of Rusa grass, etc., which is distilled in India from ginger grass. (See above, p. 33.)
The first-mentioned oil has a much finer aroma than the second. The two oils are frequently confounded, even in prominent works of reference.
When oil of geranium or of rose geranium is directed to be used, the French (or Algerian, or Spanish) oil should be employed. These cost more than twice as much as the so-called Turkish or palmarosa oil.
