iStock_000047822080LargeRose geranium (Pelargonium graveolens) is probably most famous for its traditional uses regarding skin health and uplifting mood.1 Recently, I began using it for skin health and noticed a little application could help maintain a healthy glow!

So, my mind started to wonder, “what else can geranium do?” You know where that led me…straight to PubMed.


1. Of Mice & Fungus

In an in vitro and rodent study, geranium essential oil and geraniol application, “suppressed Candida cell growth in the vagina and its local inflammation when combined with vaginal washing.” Interestingly, growth inhibition of this fungus was only seen if washing and the use of the essential oil were combined.2


2. In Vitro Inhibition of Certain Microbes

Several studies have demonstrated in vitro inhospitable activity of geranium to certain microbes.3-5 One study concluded that when adding geranium to microbe infested quiche, which was done in order to determine its effect on food spoilage, “At 500 ppm, there was a greatly increased inhibition of microbial growth using the Pelargonium essential oils, which was comparable with that of commercial thyme, clove, geranium and coriander oils. As there is no evidence for the toxicity of any of these novel Pelargonium oils, and their odour does not make the delicately flavoured quiche filling unpalatable, there is a strong potential for their use in food processing.”6

Any nutrition geniuses out there want to try this geranium-flavored quiche and report back?


3. Immune Supportive

An Asian study reported that pharmacological experiments with citronellol, citronellyl formate, geraniol and citronellyl acetate demonstrated that geranium could support immune modulation.7 Furthermore, in a few rodent studies, geranium was shown to have inflammation modulating activity. 8-9


4. May Repel Unwanted Critters

In a study using “biological tests with a vertical filter paper bioassay,” where ticks must cross an area of the paper treated with repellent to reach their model victims, the authors concluded, “Most repellents are marketed with much higher concentrations of active ingredient than the concentrations of the natural repellents tested herein; therefore, effective compounds, such as (-)-10-epi-?-eudesmol, found in geranium oil, have the potential for commercial development.”10


5. Temporary Relief of Nerve Discomfort

A study reported on temporary relief from nervous system discomfort with the use of topical geranium.11


6. May Help With Modulating Nose Bleeds

In a small human cohort trial, it was reported that, “A sesame/rose geranium oil compound can significantly reduce the epistaxis severity scores of patients with hereditary hemorrhagic telangiectasia-related epistaxis.” 12



All this diversity in a little drop of oil, the power of synergism exhibited again! Geranium’s suggested use is applying 1-2 drops topically or to be used aromatically. It hasn’t been added to the list of secrete ingredients in world-renowned quiches yet!
