Anamu (Petiveria alliacea), also known as guinea hen weed or mucura, has a long history of traditional use in Central and South America and the Caribbean for treating colds, flu, and other respiratory infections. Folk medicine practitioners often prepare teas or decoctions from the leaves and roots, relying on anamu’s reputed antiviral and immune-boosting properties. The rationale is based on its use in indigenous and rural herbal medicine systems rather than on robust clinical evidence.

Scientifically, some in vitro studies have demonstrated that extracts of anamu possess activity against viruses such as herpes simplex virus and influenza. These effects are thought to be due to the presence of sulfur-containing compounds and flavonoids. However, there are no published clinical trials directly evaluating anamu’s efficacy for colds or its antiviral effects in humans. Most available evidence is preclinical, involving cell cultures or animal models, and cannot be directly extrapolated to human health outcomes.

In summary, the use of anamu for colds is primarily based on traditional practices, with weak supporting evidence from laboratory studies. There is a lack of high-quality clinical research to validate its effectiveness for this purpose in humans.
