Cramp bark, also known as Viburnum opulus, is a deciduous shrub native to Europe, Asia, and North America. It is commonly used in traditional herbal medicine for its purported relaxing and sedative properties. The bark and berries of the cramp bark plant are used to make herbal teas, tinctures, and extracts. It is believed to help alleviate muscle spasms and cramps, as well as reduce anxiety and promote sleep.
Cramp bark is also used in cosmetics and skin care products due to its astringent and toning properties. It should be noted that while cramp bark is often used in traditional medicine, there is limited scientific evidence to support its effectiveness and it should not be used as a replacement for professional medical care.
