Rose geranium oil is a wonderful rose-scented essential oil that has been used in herbal medicines for centuries. The potential benefits of rose geranium oil include its ability to act as a natural anti-depressant, an analgesic for arthritic and nerve pain, and an anti-inflammatory for skin conditions. It is a popular choice for a soothing oil in aromatherapy.
What is Rose Geranium Oil?
Rose geranium oil is extracted from the leaves and stem of the rose geranium plant by steam distillation. Rose geraniums are small pink or lavender flowers, quite unlike the big blooming geraniums. Rose geraniums belong to the Pelargonium genus, commonly known as scented geraniums. These pretty flowers have a light scent reminiscent of rose, with tones of lilac, citrus, and lemongrass; however, the maximum scent comes from the leaves of the plant. This rose-like fragrance of the leaves is why rose geranium is used to infuse flavor into tea, sugar, baked goods, preserves, syrups, essential oils, and cosmetics. 
Rose geranium oil, leaves, and flower extracts also have antifungal, antibacterial, antiviral, and pesticidal properties, according to research studies. The essential oil and extract are also used in natural pesticides, herbal medicines, and aromatherapy. 
Benefits & Uses
Unlike many essential oils, rose geranium oil is also considered highly safe for ingestion. Geranium oils are given the GRAS status (Generally Recognized As Safe) and approved by the USFDA for food use. Let us look at the science-backed benefits and uses of rose geranium oil in detail.  
The main constituents of the oil – citronellol, geraniol, and linalool – are known to possess anti-inflammatory activities. A 2013 animal model showed that the topical application of rose geranium oil helped reduce the inflammation in rat paws and ears. The research study concluded that the essential oil may have good potential for the development of anti-inflammatory drugs.   
How To Use: A few drops, diluted with a carrier oil, can be topically applied to reduce inflammation and pain in the case of rheumatoid arthritis, canker sores, and bacterial or fungal skin infections.

Rose geranium oil is often used in aromatherapy to calm anxiety and other nervous conditions. Anecdotal evidence shows that the oil works as an anti-depressant and helps lift the spirits. It can be useful during mood swings related to hormonal shifts as it both soothing and energizing. While there are no studies that can back this claim, a 2017 study concluded that the fragrance of rose oil helped in physiological and psychological relaxation, and had analgesic and anti-anxiety effects. Rose geranium oil has a lighter but similar fragrance notes as rose oil. 
How to Use: Use 5-6 drops in a diffuser with citrus-like neroli, bergamot, or sweet orange to create an uplifting fragrant space.
Rose geranium oil is often used to treat skin conditions due to its astringent, antiseptic, antibacterial, and anti-inflammatory properties.

How to Use: Human studies are required to fully understand the therapeutic potential of this oil for people with diabetes. While the antioxidant-rich oil has proven to reduce oxidative stress related to diabetes, professional medical advice should be sought on the exact dosage as a safe alternative antihyperglycemic drug.
