The history of the use of Laminaria digitata is presented. Economically, laminaria has primarily been used as a source of algin. During the 19th century, laminaria were used as an aid in cervical dilatation. Their use persisted in France, Germany, and Japan, but in England, problems of infection associated with laminaria led English physicians to adopt steel dilating instruments. Recently, the liberalization of abortion laws has revived interest in laminaria tents for second trimester aboriton. The primary advantages of laminaria tents for cervical dilatation are that they save time, are efficient, and improve patient comfort.
