Lycopus is a genus of flowering plants commonly known as water horehound. These plants typically grow in wetland areas, such as marshes and along riverbanks. They are characterized by their small, mint-like leaves and tiny white or pale purple flowers that bloom in clusters. Lycopus species are often used in traditional medicine for their potential health benefits, including treating respiratory issues and promoting relaxation. In addition to their medicinal uses, Lycopus plants play an important role in their ecosystems. They provide habitat and food for various wildlife, including insects and birds. Their presence helps maintain the health of wetland environments, making them valuable for biodiversity and water quality.
