Geranium Oil

Geranium Oil (Pelargonium graveolens)

By Hwaa Irfan

The Geranium essential oil that is commonly used within the practice of aromatherapy is Pelargonium graveolens although there are over 200 species of this group. It bears no similarity with the hardy geraniums of Europe.

Pelargonium graveolens is native to South tropical Africa, (Mozambique, South Africa, and Zimbabwe), and is a member of the Geraniaceae family of the plant kingdom. Its scented petals are used on a large scale in the perfume industry being one of the top 20 globally in perfumery, though the scent of different varieties range from citrus, rose, mint, and even nutmeg.

This delicate perennial plant is a flower producing shrub that from its woody beginning produces tender shoots. It is covered in fine hairs from the stem to the pink flowers in some varieties. The flowers have four petals and appear in clusters that extend from a long stalk making it vulnerable to strong winds. The pink petals are streaked with purple. The triangular leaves have variegated lobes with distinct veins emit a fragrance on being robbed. The scent of the rose geranium as it is sometimes called is like that Damask rose.

The essential oil of Pelargonium graveolens is extracted through steam distillation of the flowers, leaves, and stems of the plant.  When looking to buy, look out for a yellowish-green color, which becomes stronger in the following order Reunion, Bourbon, Egyptian, i.e. country of production.

There are three distinctive types of Geranium essential oil: Bourbon, Reunion, and Egyptian. The best organic geranium oil is distilled in Egypt (Bourbon variety), with the conventional type produced in China, Madagascar (Bourbon variety), and Russia. Of course with such a popular oil to the perfume industry, adulteration is bound to occur. In the Chinese blend one can find the oil has been adulterated with Indian geranium oil which contains diphenyl oxide. In the Chinese and Bourbon blends one can find adulteration using monoterpene alcohols and esters, especially formats, copper, chlorophyll (for colour), and sometimes dibutyl sulphides. Some oils are adulterated with citronella oil, and/or palmarosa.

Chemical Properties

Some of the bioactive constituents of Geranium essential oil are:

  • 6,9-guaidiene (very high in Reunion variety, but low in Bourbon)
  • 10-epi-γ-eudesmol (not present in the Reunion oil, but high content in Egyptian variety)
  • Citronellol
  • Citronellyl formate (not present in Egyptian variety)
  • Citronellyl propionate
  • Eugeneol
  • Geraniol
  • Geranyl formate (not present in Egyptian variety)
  • Geranyl tiglate
  • Geranyl propionate
  • Isomenthone (high content in Bourbon and Egyptian variety)
  • Ketone
  • Linalool (high content in Reunion variety)
  • Menthone (in some varieties, not all)
  • Myrtenol
  •  Methylhexaneamine
  • Terpineol
  • Sabinene (terpene)

Geraniol and Citronellol in the main are responsible for the rose scent that is loved by many.

Studies at the Shanghai Institute of Technology found the antioxidant qualities of Pelargonium graveolens was present in the buds, the stems and the leaves, and that leaves collected in the afternoon had the strongest antioxidant properties. Antioxidants are naturally occurring molecules capable of counteracting the damaging effects of oxidation in the body, which can take the form of vitamins or minerals. Antioxidants help to neutralized free radicals than can damage various cellular structures.
