Citral


Citral

Citral is an organic compound that creates the sweet, tart aroma of lemons.  Citral occurs naturally in many plants, such lemon myrtle, lemongrass, lemon verbena, and orange. But most importantly, it is one of the compounds present in lemon essential oil, which has been found to have many health benefits.
Lemon oil has been found to have anti-inflammatory properties, so it can help boost your immune system and fight respiratory conditions.  It benefits the lymphatic system, which protects you from harmful pathogens and reduces swelling in your lymph nodes. 1 
If you are looking for a way to get rid of nausea, especially if you are pregnant and experiencing morning sickness, lemon essential oil can serve as a natural and effective remedy.  A 2014 clinical trial investigated the effect of lemon inhalation on nausea and vomiting during pregnancy.  Researchers found that there was a statistically significant difference between the control and intervention groups in the mean scores of nausea and vomiting, with the lemon oil group having much lower scores. 1
