Legends, Myths and Stories

According to the old-timers, eating too many hazelnuts can cause gas, stomach ache, and headache. They claimed if a snake was struck with a hazel wand, it became stunned, because it is pliable and will wind closer around the snake to limit its motion. Country folk claim if the hazel nuts have thick shells, the winter will be bleak; if their shells are thin, the winter will be mild.

Uses

Native Americans historically prepared a tea from hazelnut bark to address hives and fevers, and applied bark poultices to cuts and old sores. Traditional herbalists compared the plant to hawthorn, recommending it to support the heart and the arteries, while also attributing aphrodisiac properties to it. Additionally, Native Americans and historical physicians utilized the twig hairs in traditional remedies intended to expel worms.
