This article is about organic essential oils to calm yourself emotionally. And as emotions at times turn into physical sensations like nausea I also mention one to solve that.
When I was the caretaker of my mother I often rubbed her hands with lavender oil. Probably the touching did just as much as the oil. Nevertheless, we both enjoyed this habit and it calmed her considerably.
It would have been better to rub her neck and shoulders with the lavender oil but she didn’t like that. Our compromise worked fine because the scent got into her nose anyway. Essential oils work so well because they act directly on the olfactory system in the brain when inhaled.
