Throughout North America, you can find small patches of purple flowering plants commonly known as blue vervain. However, the scientific name of this well-known herb is Verbena hastata and is also known by the name swamp verbena. These plants are quite robust and are able to resist drought, making them very reliable sources of this powerful herb.The organic constituents in the leaves, roots, and flowers possess certain qualities that are beneficial for human health. Blue vervain has been used for thousands of years and is not limited to North America. Even the Romans used verbena (another common name) to treat a variety of medical conditions, and the flowering herb was also a popular remedy among the Native Americans. The herb is primarily used now by herbalists and traditional medicine practitioners.
