Geraniol Molecule

Geraniol has a sweet, floral, fruity, rosy, waxy, citrus smell to it. The terpene has been known as a good mosquito repellent, but unfortunately attracts bees. Geraniol is toxic to bacteria and certain fugi. Further uses for the terpene include anti-inflammatory action. Also as a topical drug enhancer and anti-inflammatory, geraniol has proven useful.

The effects of Geraniol on relieving pain were investigated in mice. Upon administration, geraniol significantly affected the number of Fos-positive cells in pain neuron sites in the brain, signifying an analgesic outcome.


Geraniol was examined as a fungicide for Candida albicans. Administration of the compound inhibited pseudohyphae and chlamydoconidia formation of the fungus. In the time-dependent kill curve assay, fungicidal activity for MIC × 2 started at 2 h for the ATCC 76485 strain, and at 4 h for the LM-70 strain..


Geraniol has been confirmed to be toxic against several bacteria species, Escherichia coli O157 : H7(VT(-)), Clostridium difficile DSM1296, Clostridium perfringens DSM11780, Salmonella typhimurium 3530 Salmonella enteritidis S1400, and Staphylococcus aureus

Topical drug enhancer

Geraniol co-application with a couple topical drugs was concluded to enhance the skin penetration in delivering these medicines in mice.


BALB/c mice were induced to have an inflammatory response by treating with
aminobisphosphonate alendronate and bacterial muramyldipeptide. Geraniol, and geranylgeraniol were effective in preventing the inflammation induced by alendronate-muramyldipeptide. This could be an effective treatment for mevalonate kinase deficiency.
