The uses of lemon essential oil include easing stress, elevating mood, stimulating the immune system, alleviating pain, and promoting weight loss. In addition, lemon essential oil might be used to address conditions such as acne, athlete's foot, and warts.

Although research on the health effects of the aromatherapeutic use of lemon essential oil is limited, there's some evidence that lemon essential oil may offer certain benefits:

• Anxiety: Lemon essential oil is known to be a natural stress reliever. Inhaling this aromatic oil has been shown to stimulate serotonin and dopamine production, which contributes to decreased anxiety.
• Mood: Preliminary research indicates that lemon essential oil can act as a mood enhancer. Researchers have found that inhaling the aroma of lemon essential oil improves mood and promotes relaxation.3
• Weight loss: Lemon essential oil has been shown to suppress weight gain and improve metabolic markers, such as cholesterol and triglycerides.4 However, due to a lack of clinical trials testing the effects of lemon essential oil on fat breakdown, it's too soon to recommend it as a weight-loss aid.
