Geraniol is a monoterpenoid with the molecular formula C10H18O. It is also known by other names such as lemonol, beta-geraniol and Guainol. It is a plant oil extracted from Geraniums and lemongrass. Cannabis strains that are rich in linalool, which is another major terpene, are usually also high in geraniol. These strains include Afghan, Amnesia Haze and Skunk genetics. Geraniol is the main constituent of rose oil, citronella oil and palmarosa oil. It is a phytonutrient present in lemon, bergamot, carrot, coriander, geranium oil, lavender oil, ylang ylang oil, nutmeg, orange, blueberries and black berries.
Geraniol contains anti-inflammatory properties that have been found to exert anti-inflammatory effects in a study with rats with diet-induced atherogenesis. The study reported that Tissue Remodeling (which plays a significant part in the inflammation and oxidative stress phase) is greatly reduced and even prevented by the anti-inflammatory and free radical scavenging effects of geraniol. Geraniol is a pale yellow oily liquid. Pure Geraniol is a colorless liquid. It has sweet rose aroma. Because of its aroma, it is mainly used in perfumes, lotions, creams, detergents, after shave lotions and soaps and bathing products. Geraniol is used as an analgesic to relieve pain and is also an effective topical drug enhancer.
Geraniol is also used in flavors such as pineapple, peach, raspberry, grapefruit, red apple, plum, lime, orange, lemon, watermelon and blueberry. It is also used as a flavor enhancer in candies, ice creams and baked goods. . It is also used as an aroma additive in foods to enhance the smell of the foods. Thus, it serves as an important flavoring agent in food industries.
The strong antiseptic properties of geraniol have been found to be 7 times stronger than that of phenol. The natural antioxidant activities of geraniol essential oils are effective at preventing certain types of cancer. In human cell culture studies, it has been found to inhibit the growth of cancer cells and has been successfully used in the treatment of lung, breast, skin, prostate, colon, hepatic, and pancreatic cancers. A study has found that geraniol inhibits the growth of cancer cells and the polyamine biosynthesis in colon cancer. The study found that geraniol reduced the growth of cancer cells by 70% and also inhibited the synthesis of DNA.
A 2005 study published in Biochemical Pharmacology showed how geraniol inhibited the proliferation of MCF-7 breast cancer cells. A published in 2016 in the Journal Cancer Medicine showed that geraniol was able to inhibit the growth of prostate cancer cells by altering the expression of master genes involved in cell proliferation. This prevented cancer cells from spreading to other parts of the body.
Geraniol is very effective in assisting in pain reduction. Its anti-inflammatory properties reduce tissue swelling and reduce pain caused by acute and chronic conditions. It is highly effective in treating the discomfort and pain experienced during menstruation. A few drops of geranium essential oils in the bath will calm and relax the nervous system and improve blood flow to reduce inflammation that causes pain. A study in the Journal of Neuroscience Research showed that geraniol also works as a neuroprotectant, which means it helps preserve the structure and function of nerve cells. This would make geraniol particularly useful for the treatment of neuropathy in people with diabetes. Neuropathy is a condition where damage to the nerves can cause pain, numbness, and weakness in the limbs.
