Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Smartweed (Polygonum pensylvanicum and related species) has a history of use in traditional herbal medicine, particularly in North America and Europe. Indigenous peoples and early settlers have employed smartweed for a variety of ailments, including fevers and colds. The traditional use primarily involves making infusions or decoctions of the aerial parts of the plant, which are then consumed to "break" fevers or to support the body during colds. The rationale for its use is largely based on its purported diaphoretic (sweat-inducing) properties, which were believed to help the body expel illness through perspiration.

However, scientific evidence supporting smartweed's efficacy for colds with fever is very limited. Few, if any, clinical trials have investigated its effects on fever or upper respiratory tract infections in humans. Some laboratory studies indicate that smartweed contains various phytochemicals, such as flavonoids and tannins, which possess mild anti-inflammatory or antimicrobial effects, but these findings have not been directly linked to relief from fever or cold symptoms in a clinical context.

In summary, the use of smartweed for colds with fever is justified by tradition rather than robust scientific validation. The evidence rating of 2 reflects the presence of longstanding traditional use and some basic phytochemical rationale, but a lack of controlled studies or strong scientific confirmation of efficacy for this particular indication.
