Vervain (Verbena officinalis) has a long history of traditional use in herbal medicine, particularly in Europe, where it has been employed as a folk remedy for various respiratory complaints, including bronchial congestion. Herbalists historically used vervain as an expectorant—an agent that helps to clear mucus from the airways—often preparing it as a tea or syrup. Texts from the 19th and early 20th centuries, as well as references in traditional Western herbalism, describe vervain as helpful for coughs, colds, and bronchitis. The plant contains several bioactive compounds, such as iridoid glycosides and flavonoids, which have been suggested to have mild anti-inflammatory and antispasmodic effects, but these claims are largely based on traditional knowledge and anecdotal reports.

Scientific studies specifically examining vervain’s efficacy for bronchial congestion are limited. While some laboratory research has explored the general anti-inflammatory and antimicrobial properties of vervain extracts, there is a lack of robust clinical evidence to support its use for bronchial congestion in humans. As such, the justification for using vervain for this purpose is primarily rooted in traditional herbalism rather than modern scientific validation.
