Lemongrass oil is believed to relieve jet lag, headaches, nervous exhaustion, and stress. It boosts the parasympathetic nervous system, for faster recovery from an illness, and stimulates glandular secretions. It helps tone muscles and tissue, hence relieving muscle pain.
It's useful for treating sore throat, laryngitis, and fever, and helps stop the spreading of infection. It helps with colitis, indigestion, and gastroenteritis. It clears oily skin and reduces excessive perspiration. It can irritate the skin, however, so care must be taken when used on skin. Avoid use during pregnancy.
