Synopsis

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

Bioflavonoids, a diverse group of plant-derived polyphenolic compounds, have a long history of traditional use in supporting respiratory health, including the management of allergy symptoms. Historically, they were derived from citrus fruits and used in folk medicine for their purported anti-inflammatory and capillary-strengthening effects. The most commonly referenced bioflavonoids in the context of allergies include quercetin, hesperidin, and rutin. Traditional use stems from observations of their potential to reduce symptoms such as sneezing, nasal congestion, and watery eyes, which are common in allergic rhinitis and other respiratory allergies.

Scientific research on bioflavonoids for allergies shows some promise, particularly for quercetin, which has been studied for its mast cell-stabilizing and antihistamine effects in vitro and in animal models. However, robust clinical trials in humans are limited, and results are mixed. Most studies are small, not well controlled, or use isolated compounds rather than mixtures of unspecified bioflavonoids. Therefore, while there is a rationale for their use and some historical and limited scientific support, bioflavonoids as a class (especially when unspecified) lack strong, high-quality evidence for efficacy in treating or preventing respiratory allergies.

In summary, the use of bioflavonoids for respiratory allergies is primarily justified by traditional use and limited preliminary scientific data, but not by definitive clinical evidence.
