It is native to Europe, Northern Africa, and Western Asia but has been introduced to other parts of the world for its medicinal properties. The plant has a long history of use in traditional medicine for its anti-inflammatory, analgesic, and diuretic properties. It has a tuberous root that can grow up to 1 meter long and is used to extract the plant’s active ingredients.

Its fruit is a greenish-yellow berry that turns red as it matures. The tuberous root is usually white on the inside and brown on the outside, with a rough, scaly texture. The plant’s stem is thin and twines around other plants for support.
