Geranium essential oil (Pelargonium roseum) is frequently used in perfumes, cosmetics, and aromatherapy products, largely due to the pleasant scent created by its constituents, including citronellol and geraniol. The two powerful constituents also play a powerful role in the health and beauty benefits associated with geranium essential oil. Here’s a quick look at just a few of geranium oil’s top benefits.
Citronellol has been used as an antibacterial, antimicrobial,and anti-inflammatory agent since the Middle Ages. Today, numerous research studies have confirmed these properties, as well as its antiviral and antimalarial properties, in geranium oil’s most prevalent constituent . In particular, citronellol’s anti-inflammatory abilities have been extensively studied. A 2013 study found that geranium oil is safer and more effective at relieving inflammation than anti-inflammatory medications because it has significantly fewer side effects . It has also been shown to help reduce pain, although further research is needed to determine exactly how the citronellol in geranium oil does this.
Geraniol is a known natural antioxidant that shows promise in helping to fight and prevent cancer. A study published in 2016, researchers indicated that geraniol is able to control signaling pathways and molecules in the body that are involved in various biological processes associated with cancer . This leads them to believe that geraniol’s ability to inhibit tumor growth, which has already been proven in pancreatic cancer, is something that should be studied further .
In addition, as an antioxidant, geraniol has the potential to slow down the signs of aging by minimizing the appearance of wrinkles and tightening the skin, which can also extends to the gum line, thus reducing the loosening and loos of teeth.
