Synopsis

Source of validity: Traditional
Rating (out of 5): 1

Fennel (Foeniculum vulgare) has a long history of use in traditional medicine systems, including Ayurveda and Traditional Chinese Medicine. Traditionally, fennel seeds and extracts have been used to alleviate a variety of ailments, including digestive issues, respiratory conditions, and mild fevers. In folk medicine, fennel is sometimes combined with other herbs as part of remedies intended to "cool" the body or help reduce feverish symptoms, likely due to its perceived anti-inflammatory or soothing properties.

However, scientific evidence specifically supporting fennel’s efficacy in treating or reducing fever is very limited. Most modern research on fennel focuses on its antioxidant, antimicrobial, and anti-inflammatory activities, as well as its use in digestive and respiratory complaints. While these properties could theoretically have some indirect benefit in fever management—such as reducing inflammation or fighting infection—there are no robust clinical studies demonstrating that fennel directly reduces fever in humans. As such, its use for fever is primarily justified by traditional practice rather than scientific validation, and the overall strength of evidence is weak (rated 1 out of 5).

In summary, fennel's use for fever is rooted in traditional medicine, with minimal scientific backing. Anyone considering using fennel for fever should consult a healthcare professional, especially in the context of persistent or high fever.
