Yes Essential oils mainly contain terpenoids, esters, aldehydes, alcohols and organic acids. These substances are easily dissolved in oil, and there is a lot of oil in the stomach. If the user has oily skin, rubbing his stomach with essential oil for a long time will lead to hair follicle blockage and skin diseases such as acne, folliculitis and furuncle, so rubbing his stomach with essential oil for a long time is harmful.
