Lemon Essential Oil

Lemon essential oil, cold-pressed from the peel of Citrus limon, has a long history of household and folk use for its bright, uplifting scent and practical cleaning applications. Research suggests that inhaling lemon oil aroma may support mood and promote a sense of alertness, with some studies indicating positive effects on focus, mental fatigue, and feelings of tension. Preliminary laboratory research has also explored its antimicrobial properties, showing potential activity against certain bacteria and fungi on surfaces, which aligns with its traditional use as a natural household freshener. A small number of studies have looked at its role in easing mild nausea, particularly through aromatherapy. As with all essential oils, lemon oil is typically diffused or applied topically in diluted form, and it may increase skin sensitivity to sunlight.
