The elder tree held a magical reputation in Western European folklore, deeply intertwined with goddess cults such as those of Venus and the Norse fertility goddess Freya. In Scandinavia, planting an elder near your house, especially by the kitchen, was believed to protect the home and fill it with love. Elders were thought to be immune to lightning strikes, offering further protection. The tree was also seen as a portal to the spirit realm; standing under an elder on midsummer eve supposedly enabled one to see the king of the elves.

Elder was highly valued in folk medicine despite its mild toxicity. The plant contains prussic acid, which can cause vomiting or diarrhea in small doses. It was believed that elder bark cut from the bottom upwards acted as an emetic, while bark cut from the top downwards served as a laxative. The flowers and berries were used to treat colds and flus. To ward off evil spirits and relieve toothache, people would put a twig from an elder tree in their mouths.

However, one couldn’t just take from an elder tree without consequences. The tree was believed to be inhabited by an Elder Mother or Elder Woman, a protective spirit (some say she originated as a localised version of Freya) who would avenge any harm done to the tree. People would ask her for permission three times before picking out cutting anything from the tree. Cutting down an elder without planting a new one was considered bad luck, with folk stories recounting the deaths of those who did so, presumably at the hands of a vengeful Elder Mother.

The Elder Mother also disapproved of using elder wood for furniture or tools. Stories tell of her disturbing babies who slept in cots made from elder wood or in rooms with elder paneling by pulling their legs. However, if treated with respect, the Elder Mother, and sometimes an entire elder family with elder women, men, and children, would help busy housewives by churning butter or polishing copperware at night.

Some stories even tell of the elder tree itself being sentient and animate, with one story from Copenhagen telling of how the elder tree in a courtyard would move to a new position every night and look through the windows of the rooms inside.

The Elder Mother exemplifies traditional Germanic belief in wights, collective spirits or deities connected to a locality like a landscape, river, or farmhouse, and sometimes to families or bloodlines. Wights are neither good nor evil but are forces of nature to be reckoned with. Respect them, and they will help you; disrespect them, and they can destroy you.
