 Description 
Balsam herb is an ancient, perennial, edible wild spice, aromatic and medicinal plant from the temperate latitudes of Asia and North America. The plant, also known as St. Mary's herb, has been cultivated in the southern regions of Europe since ancient times. In the early Middle Ages, the medicinal plant was used as a helpful remedy for fever, liver weakness and menstrual problems.
