The yellow-flowered yellow loosestrife (Lysimachia vulgaris) is a common shore plant that flowers in late summer. This plant has many uses. The leaves and flowers of yellow loosestrifes have traditionally been used in poultices to treat wounds. The cosmetics industry uses the plant to make lotion, and a decoction of yellow loosestrife flowers can be used to bleach one’s hair.
Its roots are used to make brown dye, while the flowers are used to produce yellow dye. Fresh and dried yellow loosestrife shoots repel insects, as a result of which the plant is also used to make mosquito repelling incense. It is also used as an ornamental garden species alongside or instead of the dotted loosestrife.
