Pelargonium Graveolens (Geranium) for Hormonal Balance

Research suggests that Pelargonium graveolens (rose geranium) may have relevance to hormonal balance, though the evidence base is limited and draws from diverse study types. An animal study found that geranium essential oil helped restore disrupted sex hormone levels and related gene expression in male rats exposed to titanium nanoparticles, while two studies in climacteric (menopausal) women — including one randomized controlled trial — found that aromatherapy massage incorporating rose geranium reduced menopausal symptoms and improved cardiovascular markers associated with hormonal changes. A cell-based assay study produced mixed findings, notably identifying geranium-containing combinations as non-estrogenic or minimally estrogenic, which may be relevant to safety considerations around hormonal claims but does not confirm a direct hormonal effect. Overall, while the available studies lean in a supportive direction, they are few in number, rely heavily on animal models and aromatherapy delivery rather than direct supplementation, and are not sufficient to draw firm conclusions about geranium's role in hormonal regulation in humans.
