Synopsis

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

Fennel (Foeniculum vulgare) has a longstanding history of use in traditional medicine systems, particularly in the Mediterranean, Middle Eastern, and South Asian cultures. It is employed for its anti-inflammatory, antimicrobial, and expectorant properties, which are believed to help relieve symptoms associated with respiratory conditions, including sinus infections (sinusitis). In folk medicine, fennel seeds are often prepared as teas or infusions to help clear nasal passages and reduce congestion. The essential oils in fennel, particularly anethole, have demonstrated some antimicrobial and anti-inflammatory activity in laboratory studies, which may provide a theoretical basis for its traditional use in sinus complaints.

However, there is a lack of robust clinical studies directly evaluating fennel’s efficacy in treating or alleviating symptoms of sinus infections in humans. Most evidence remains anecdotal or is derived from its generalized use for respiratory complaints. The rating of 2 reflects that while there is a strong tradition and plausible mechanism, high-quality scientific validation is limited. Thus, fennel’s use for sinus infections is justified primarily by traditional knowledge rather than rigorous scientific research. Individuals interested in using fennel for sinus infection should do so as a complementary measure and consult healthcare professionals, especially if symptoms persist or worsen.
