Lemongrass Oil is a great addition to various skin care and cosmetic products, such as soaps, deodorants, shampoos, lotions, and tonics. It also works as an air freshener and deodorizer, especially when blended with other essential oils like geranium or bergamot. Simply put it in an oil burner, diffuser, or vaporizer. Lemongrass oil is also known for its ability to repel insects, such as mosquitoes and ants, due to its high citral and geraniol content. Spray it around your home, diffuse it, or rub a diluted mixture on your skin.
