Lemongrass oil can be extracted, and it's been used by healthcare providers to treat digestive problems and high blood pressure. It has many other potential health benefits, too. In fact, lemongrass essential oil is a popular tool in aromatherapy to help relieve stress, anxiety, and depression.
Essential oils of peppermint, orange or lemongrass kill most strains of fungal and bacterial infections.
People can add lemongrass essential oil to a carrier oil, such as jojoba or coconut oil, and massage it into the skin. Adding several drops of the essential oil to boiling water and inhaling the steam through the nose, keeping the eyes closed, and covering the head with a towel is another way to use it.
