When Katie was a kid, she would mix “potions” with her cousin on the stovetop, sometimes with disastrous results. (Aunts generally love when you clean out their make-up cabinet making potions.) The childhood obsession took on an entirely new meaning later in life, when she suffered from brutal chronic migraines. Like ones that sent her in and out of the hospital. Scents triggered many of her headaches—especially heavy artificial fragrances—so she used her old penchant for making beauty products to heal herself. A line of products with natural botanicals and essential oils was born, many of them relying on methods that have been used for centuries, like her delectable salves.
