Betel (Piper betle) leaves have been used traditionally in various Asian cultures as a home remedy for sore throat and other minor throat ailments. The use is particularly common in South and Southeast Asia, where betel leaves are chewed alone or with other ingredients for their perceived medicinal properties. The traditional rationale is that betel leaves possess antimicrobial, anti-inflammatory, and soothing properties, which could help reduce throat discomfort and fight infection. Historical texts in Ayurveda and folk medicine sources often mention the use of betel leaf preparations (such as decoctions or gargles) for soothing sore throats and coughs.

However, scientific studies specifically investigating the effectiveness of betel leaf for sore throat in humans are limited. Some laboratory research points to antimicrobial activity of betel leaf extracts against a range of bacteria and fungi, suggesting a plausible mechanism for its traditional use. Additionally, certain studies have documented the anti-inflammatory and analgesic effects of betel leaves in vitro or in animal models. Despite these promising findings, there is a lack of robust clinical evidence in human subjects directly linking betel leaf use to symptomatic relief of sore throat.

In summary, while the use of betel for sore throat is well-rooted in traditional medicine and supported by some preliminary scientific findings, there is insufficient high-quality clinical evidence to strongly endorse its efficacy for this specific condition.
