Synopsis

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

Fennel (Foeniculum vulgare) has been used traditionally in various systems of medicine, such as Ayurveda and Traditional Persian Medicine, to address respiratory ailments, including symptoms associated with rhinitis (such as nasal congestion and runny nose). The rationale behind its use is primarily attributed to its anti-inflammatory, antispasmodic, and mild expectorant properties. These effects are largely due to its essential oils, particularly anethole, fenchone, and estragole, which can help soothe mucous membranes and potentially reduce irritation in the upper respiratory tract.

However, direct clinical evidence supporting fennel’s effectiveness specifically for rhinitis (allergic or non-allergic) is limited. Most of the available data are either in vitro, animal studies, or extrapolated from its broader use for respiratory tract conditions. There are a few small studies and herbal medicine reviews suggesting fennel may have some benefit in reducing symptoms like nasal congestion due to its anti-inflammatory and antioxidant actions, but these are neither robust nor specific to rhinitis.

In summary, fennel’s use for rhinitis is rooted in traditional practice rather than strong scientific validation. While its properties suggest potential benefit, especially for mild symptoms, more rigorous, rhinitis-specific clinical trials would be required to elevate the evidence rating.
