Synopsis

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

The use of Banyan (Ficus benghalensis) for canker sores (aphthous ulcers) is primarily rooted in traditional medicine, particularly in Ayurveda and other South Asian folk systems. Historical texts and ethnobotanical surveys mention the use of various parts of the banyan tree—such as its bark, latex, or aerial roots—for oral health, including the treatment of mouth ulcers and sores. The latex is sometimes applied directly to affected areas, and decoctions of the bark have been used as a mouth rinse. The rationale is based on the purported anti-inflammatory, astringent, and antimicrobial properties of the plant, which are believed to soothe irritation and promote healing. However, direct scientific validation for Banyan's efficacy against canker sores is very limited. While some laboratory studies have reported antibacterial and anti-inflammatory effects of Ficus benghalensis extracts, these studies are mostly in vitro or use animal models and do not specifically address canker sores in humans. There are no well-controlled clinical trials supporting its use for this condition. As such, while Banyan's use for canker sores is supported by tradition and some plausible biological mechanisms, the overall quality and quantity of evidence are low. Anyone considering its use should consult with a healthcare professional.
