L like Lavender essential oil (Lavandula angustifolia)

It prevents and repairs the effects of dehydration.

This is an essential oil that we should all have at home. It is with it that modern aromatherapy is born: the story goes back to Dr. Gatefossé, chemist, who accidentally discovered his healing properties. Thanks to its relaxing, soothing, inhaling or massage power, the everyday tensions are over.
Beware though, some may develop an allergy with this essential oil. It is rather rare, but place a drop in the elbow crease and wait 15 min to evaluate the skin tolerance.
