Lemongrass essential oil is extracted through the process of steam distillation of dried lemongrass. Lemongrass is known by the scientific names Cymbopogon Citratus or Andropogon Citratus. The main constituents of its essential oil are Myrcene, Citronellal, Geranyl Acetate, Nerol, Geraniol, Neral, Limonene and Citral.

As the name implies, lemongrass smells just like lemon but it is milder, sweeter, and far less sour.

Lemongrass oil is also known for its ability to repel insects, such as mosquitoes and ants, due to its high citral and geraniol content. Spray it around your home, diffuse it, or rub a diluted mixture on your skin.

Lemongrass oil's refreshing scent makes it a valuable aromatherapeutic oil. Its clean and calming aroma helps relieve stress, anxiety, irritability, and insomnia, and prevent drowsiness.^7, Lemongrass oil can also help relax and tone your muscles, as well as relieve muscle pain, rheumatism, period cramps, stomachache, toothache, migraines, and headaches.

Make a refreshing foot bath. Add two drops to a bowl of warm water, and soak your feet for 10 minutes. If your feet are aching, add two tablespoons of Epsom salts.
Make a massage oil by mixing it withsweet almond or jojoba oil.
Is Lemongrass Oil Safe?

Lemongrass oil is generally safe as long as it is used in small quantities (it is one of the strongest-smelling oils in aromatherapy) and properly blended with a carrier oil. Undiluted lemongrass can actually burn and injure your skin due to its high citral content, so it's best to mix it with a carrier oil. Some of the best carrier oils you can use with lemongrass oil are basil, palmarosa, vetiver oil, lavender, rose, clary sage, patchouli, ginger, fennel, geranium, sandalwood, and cedarwood.

I advise doing a patch test before applying lemongrass oil on your skin, to see if you have any adverse reactions to this essential oil.
