Lavender
Other plantsThe Accident That Led to Aromatherapy

On 25 July 1910, an explosion badly burned the hands and head of Lyon chemist René-Maurice Gattefossé. When his wounds began to become infected, he removed the dressings and applied lavender essence, whose use on burns had been described to him by growers. The episode redirected his research toward essential oils. In 1937, he published Aromathérapie, the book that gave the modern practice its name.
