Cautions
Though, there are no side effects of lemongrass oil. One still needs to follow certain guidelines while using essential oil. Never use concentrated essential oil on your skin. Mix it with a cream, gel or a light carrier oil, then only use it. If using it as a bug repellent, then mix it with a cream or oil and then use it, or spray few drops on your clothes to repel bugs. I mix lemongrass oil with aloe gel, and use it as a natural insect repellent.
