Spearmint Essential Oil: Spearmint essential oil is the gentler than peppermint oil, especially for children. Although the oils possess similar properties, spearmint contains lower amounts of menthol compared to peppermint oil. Because spearmint oil has antiseptic properties (due to the presence of menthol, myrcene, and caryophyllene), it can protect wounds, burns,  and ulcers from infection and even help them heal faster. This perennial herb originated from the Mediterranean region.
