Roman chamomile, botanically known as Chamaemelum nobile, is a perennial flowering herb in the Asteraceae family native to western Europe. It forms a low, spreading mat of finely divided leaves and daisy-like flowers with a sweet apple-like scent. The flower heads are the part most commonly used in traditional herbal preparations.

In traditional herbal practice, Roman chamomile has long been associated with calming teas, aromatic infusions, and gentle topical preparations for skin comfort. It is especially valued for its pleasant fragrance, mild character, and historic use in relaxation blends, bath preparations, and soothing evening herbal rituals.
