For mosquitoes exposed to 0.250 g/cm 3 geraniol and anisaldehyde, >70% did not finish normal blood engorgement. Additionally, studies have found that it it can be used in mouthwashes to kill harmful bacteria in the mouth, and it has a lower cytotoxic effect and higher action compared to some other commercial solutions. Plus, this study showed off the terps ability to reduce oxidative stress responsible for tissue damage (12). You can also inhale the oil directly by sniffing it. The site is secure. (1999) Incorporation of 1- 1-C-13 deoxy-D-xylulose in chamomile sesquiterpenes. This is why there are anti-barking collars that contain citronella. In citronellol-rich lines, GDP, GP and CP were detected in nearly equimolar amounts, while citronellyl diphosphate was absent, suggesting that citronellol biosynthesis may proceed by reduction of GP to CP in this species. doi:10.1016/j.phymed.04.007.2007, PubMed Geraniol - an overview | ScienceDirect Topics The data underlying this article are available in the article and in its online supplementary material.
