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

Betel leaf (Piper betle) has a long history of traditional use for managing halitosis (bad breath), particularly in South and Southeast Asian cultures. Chewing betel leaves, often combined with areca nut and other ingredients, is a customary practice believed to freshen breath and promote oral hygiene. Historical texts and Ayurvedic literature frequently mention betel as a remedy for mouth odor, attributing its efficacy to its aromatic properties and antimicrobial activity.

Scientifically, some studies have identified that betel leaf contains essential oils and phenolic compounds, such as chavicol and eugenol, which exhibit antimicrobial activity against oral pathogens linked to halitosis. However, direct clinical trials evaluating betel leaf's effectiveness specifically for halitosis are limited. While in vitro studies support its potential to reduce bacterial load in the mouth, robust, controlled human studies are lacking. Thus, the evidence rating is moderate but not strong.

It is important to note that traditional betel chewing often involves the addition of areca nut and slaked lime, both of which have been linked to oral health risks, including oral submucous fibrosis and increased cancer risk. Therefore, while the traditional use of betel for halitosis is well-established, its safety profile in the context of habitual chewing is a concern.
