Limonene


Limonene

Limonene is an organic compound responsible for creating the uplifting and energizing aroma of citrus.  It occurs naturally in many things like balsam fir, black pepper, parsley, spearmint, and it is the major component in the oil of citrus fruit peels.  In fact, limonene is often extracted from dried fruit peels for use in the redistillation process of gin.  It is also present in lavender essential oil, which has a wide range of health benefits.
A 2017 study examined the vital signs of patients in open heart surgery ICU before and after inhalation of lavender essential oil.  The results showed significant differences in systolic blood pressure, diastolic blood pressure, as well as heart rate before and after aromatherapy.  This means aromatherapy using lavender essential oil could effectively relieve stress, as well as reduce blood pressure and heart rate. 1
A 2016 triple-blind randomized clinical trial investigated the effect of lavender aromatherapy on pain severity in primary dysmenorrhea, the most common complaint in adolescents and adult young women that disturbs their daily life performance.  Students in the treatment group reported significantly less pain severity after using lavender aromatherapy for 2 months. 1
