History
Confusingly, "rose geranium" is also the common name of members of the genus Pelargonium, which are also in the Geraniaceae family and are widely grown as horticultural bedding plants. Linnaeus originally included all the species in one genus, Geranium, but they were later separated into two genera by Charles L'Heritier in 1789. Other former members of the genus are now classified in Erodium, including the plants known as filarees in North America.
Harvesting/Extraction Information
The essential oil of Rose Geranium is extracted through steam distillation of stems and leaves of the Rose Geranium plant, bearing the scientific name Pelargonium odorantissimum. The main components of this oil are alpha pinene, myrcene, limonene, menthone, linalool, geranyl acetate, citronellol, geraniol, and geranyl butyrate.

Organ-specific effects
Adverse skin reactions In a mouse local lymph node assay, Rose geranium oil was an extremely weak sensitizer. Undiluted Moroccan geranium oil was slightly irritating to rabbit and guinea pig skin, but was not irritating to mouse skin; tested at 10% on 25 healthy volunteers it was neither irritating nor sensitizing. It is non-phototoxic. Undiluted Reunion geranium oil was moderately irritating to rabbit skin, but was not irritating to mouse skin; tested at 0% on 25 healthy volunteers it was neither irritating nor sensitizing. It is non-phototoxic.
Cardiovascular effects When a laboratory-distilled Tunisian Rose geranium oil was given to alloxan-induced diabetic male rats at 75 and 150 mg/kg/day po for 30 days, blood glucose was reduced by an amount comparable with that elicited by glibenclamide, while hepatic glycogen concentration increased.
Systemic effects
Comments
In addition to China, Egypt and Morocco, Rose geranium oil is produced on a large scale in Crimea, Ukraine, Georgia, India, Madagascar and South Africa. The name ‘rose geranium’ was originally reserved for geranium oil from Reunion, which derived from a particular cultivar known as geranium Bourbon. However, the Bourbon oil from Reunion is now only produced in very small quantities, and is no longer sold on the open market. ‘Rose geranium’ oils are now offered from other sources. There is some confusion concerning the precise botanical species from which geranium oils are derived. The binomials P. capitatumand P. roseum are sometimes seen, and P. graveolens is frequently cited in aromatherapy literature. According to Tucker & Debaggio Pelargonium x asperum is a cross between P. capitatum and P. radens, while P. graveolens, the oil from which contains 30–83% isomenthone, is not in fact the source of commercial Rose geranium oil.
