This lemongrass essential oil is obtained from Cymbopogon citratus (also known as 'oil grass') from fresh or partially dried leaves by steam distillation. This oil is believed to combat fatigue and help refresh a tired body and mind. It is also a pleasant-smelling way to keep a pet free from fleas and ticks. Lemongrass contains citral, which gives lemon peel its main flavor. 

Lemongrass oil is believed to relieve jet lag, headaches, nervous exhaustion, and stress. It stimulates the parasympathetic nervous system for faster recovery from illness and stimulates glandular secretion. It helps strengthen muscles and tissues, thereby relieving muscle pain. It is useful for the treatment of sore throat, throat inflammation, and fever, and helps stop the spread of infections. It helps with colitis, indigestion, and gastroenteritis. It helps with oily skin and reduces excessive perspiration. However, it can irritate the skin, so be careful when using it on the skin. Avoid use during pregnancy. 

Lemongrass is a perennial aromatic grass that used to grow wild in India, where it is known as choomana poolu. It is also known as Indian Verbena or Indian Melissa oil and is used in Ayurveda, the ancient traditional medicine, to reduce fever and treat infectious diseases. It is therefore also called 'fever grass'.
