The so-called hay flowers are a composition of various plants that blossom during harvest time, such as grass blossoms, lych, bog-grass or trespe. Hay flowers are a by-product of hay production and consist of flowers, seeds, stems and leaves. Hay flowers are ideal as a bath additive or as a moist hot bag. They are especially recommended by midwives for pregnant women in the late weeks of pregnancy. Kneipp also appreciated the use of hay flowers.
