Lemongrass essential oil may help reduce anxiety by influencing levels of gamma-aminobutyric acid in the brain, according to About.com. Preliminary research also shows that lemongrass oil may slow the growth of certain types of fungi, such as Alternaria alternata, a fungus associated with infections in the upper respiratory tract. The essential oil may help prevent the growth of certain yeast and bacteria.

How to properly store essential oils:
Avoid heat and direct sunlight
Too much heat or sunlight can impact the quality of the oil.
Both heat and sunlight can change the chemical composition of the oil.
Too much heat can cause the oil to evaporate more quickly, making it less effective.
Too much sun can deteriorate the oil.
