According to a study published in the International Journal of Food Microbiology last year, lemon oil may be the most powerful anti-microbial agent of all the essential oils.
Another study published in Experimental Biology and Medicine found that breathing in the scent of lemon essential oils improved neurological activity that promotes the breakdown of body fat. It is also an essential ingredient for natural skin care.
Ayurvedic medicine too has been using both lemons and lemon essential oil to treat a wide spectrum of health conditions for at least 1,000 years. The health benefits of lemon essential oil have been well established scientifically.
