Geranium Essential Oil (E.O.) is derived through steam distillation of the leaves and stems of the Pelargonium graveolens plant, which is native to South Africa. The oil has a distinct aromatic profile, often described as rosy, sweet, and floral, with subtle herbaceous undertones. This fragrance has made it a popular ingredient in perfumery and cosmetic products for centuries. Historically, the plant was used in traditional South African wellness practices before its introduction to the West in the 17th century, where its use in aromatherapy and skincare began.
Methods of Application
The aroma of Geranium E.O. makes it a favored choice for inhalation. A common method is adding several drops to an electric diffuser, which disperses the oil into the air for passive inhalation. For more direct effects, a few drops can be placed on a cotton ball or tissue for personal inhalation, or the oil can be incorporated into a hot water bowl for a steam treatment. These aromatic methods are useful for influencing mood and creating a desired atmosphere.
Topical application is also effective but requires dilution before skin contact. Geranium E.O. must be blended with a carrier oil, such as jojoba, coconut, or almond oil, to prevent irritation. This mixture can be used as a massage oil or applied as a spot treatment for specific skin concerns. Diluted oil can also be added to bathwater to combine its properties with warm water immersion.
Specific Therapeutic Uses
Geranium E.O. is widely incorporated into skincare routines due to its benefits for the skin. The oil exhibits antimicrobial, antiseptic, and astringent properties, which help balance oil production, soothe minor irritation, and promote a clearer complexion. These actions are attributed to its chemical composition, which includes monoterpenoid alcohols like citronellol and geraniol. Using it diluted in a moisturizer or serum can help manage both oily and dry skin conditions.
The oil is also frequently used to support emotional balance and reduce feelings of stress. Studies suggest that the aromatic inhalation of Geranium E.O. can have a calming influence on the nervous system, which may help alleviate anxiety. This mood-uplifting and harmonizing effect is a primary reason it is employed in aromatherapy for psychological well-being.
Geranium E.O. also has utility in natural pest management. The monoterpenes citronellol and geraniol are recognized for their insect-repellent qualities. When applied topically in a diluted form, the oil can act as a deterrent against certain insects, including mosquitoes. The oil has also demonstrated insecticidal properties and has been used to reduce populations of pests like head lice.
Essential Safety and Dilution Guidelines
Because Geranium E.O. is highly concentrated, proper dilution is necessary for topical use to prevent sensitization or irritation. For general use on the body in adults, a dilution rate of 1% to 3% is recommended (approximately 6 to 18 drops per 30 ml of carrier oil). For sensitive areas like the face or for use on children, a lower concentration of 1% or less is advised.
Before applying any new essential oil blend extensively, perform a skin patch test. Apply a small amount of the diluted oil to a discreet area of skin, such as the inner forearm, and observe it for 24 hours for any signs of reaction, including redness or burning. If a reaction occurs, discontinue use immediately.
Geranium E.O. should never be ingested internally unless under the supervision of a qualified professional, as essential oils can be toxic. Caution is also advised for certain populations, including pregnant or breastfeeding individuals, because the oil may potentially stimulate hormonal activity. Individuals with existing medical conditions, such as high blood pressure or hormone-sensitive cancers, should consult a healthcare provider before using the oil.
