I started getting into essential oils as my kid refused to take traditional medicine (i.e. childrens tylenol, or cold medicine). If we forced it she would just throw it up.
So I got into the essential oils, and know take them everywhere. Great for traveling.
Peppermint ( helps for headaches, clearing sinus, pep in your step)
Lavender (relaxes you, helps you fall asleep)
Lemon ( add to your water to help detox, and clean surfaces)
On guard ( helps prevent sickness, and keep your immune system healthy, as well as clean surfaces)
