Ledum
Ledum in the heather family belongs to evergreen shrubs. There are 10 known varieties of it, growing in cold and temperate zones in coniferous forests and wetlands. Can enter into symbiosis with mushrooms. Common names for the plant include bogwort, wild rosemary, bug grass, and swamp stupor.
Marsh wild rosemary as an ornamental plant is attractive with its lush flowers during the flowering period. Branched branches in an abundance of delicate white flowers look very impressive, but decorative gardening is not too fond of this shrub.
Ledum flowers spread around themselves a rather strong, even intoxicating smell, which can lead to dizziness and headaches, so you should not bring them into the house. The small glands of the plant contain essential oils with a pungent odor and burning taste, rich in ice - this is a poison that affects the nervous system.
Infusions from wild rosemary are medicinal, used for dysentery, diabetes, and help as an expectorant for whooping cough and bronchitis. In small doses, essential oil is used in perfumery and medicine.
