Marsh Tea (Ledum palustre), also called wild rosemary, has a history of traditional use in folk medicine for respiratory ailments, including spastic cough. In various northern European and Siberian traditions, preparations of marsh tea—such as infusions or decoctions from its leaves—were used to alleviate symptoms of cough, bronchitis, and other respiratory tract irritations. The plant contains essential oils (notably ledol) and flavonoids, which were thought to provide expectorant and antitussive effects. However, scientific studies directly supporting its efficacy in treating cough—especially spastic cough—are sparse. Most references in modern herbal compendia and ethnobotanical sources cite only anecdotal or traditional use, with little or no clinical research or controlled trials confirming its effectiveness or safety for this indication. Furthermore, marsh tea is considered potentially toxic due to the presence of ledol and other volatile oils, and its use is not recommended in modern herbal medicine due to risks of poisoning, especially in children. In summary, while marsh tea has a well-documented traditional use for spastic cough, there is limited scientific validation, and safety concerns outweigh potential benefits.
