Quince (Cydonia oblonga) has been traditionally used in some cultures for various medicinal purposes, including the treatment of skin conditions such as boils. The traditional use of quince for boils is primarily rooted in folk medicine, where different parts of the plant—such as the fruit, seeds, and leaves—are sometimes applied topically or used in poultices. Historical texts and anecdotal reports suggest that quince was valued for its purported anti-inflammatory and soothing properties, which were believed to help reduce swelling and promote healing of skin lesions like boils.

However, there is very limited scientific research supporting the efficacy of quince specifically for the treatment of boils. Some laboratory studies have identified mild antimicrobial and anti-inflammatory properties in quince extracts, but these findings are preliminary and not directly linked to clinical outcomes for boils. No controlled clinical trials have evaluated quince as a treatment for this condition. As a result, the use of quince for boils remains primarily justified by historical and traditional practices rather than by modern scientific validation.

In summary, while quince has a history of traditional use for boils, current evidence supporting its effectiveness is weak and largely anecdotal, meriting a low evidence rating.
