Rating (out of 5): 1

Rue (Ruta graveolens) has a long history of use in traditional medicine, including European and Mediterranean folk practices. It has been used for a variety of ailments, such as inflammation, pain, and infections. In the context of canker sores (aphthous ulcers), Rue has been applied topically or used as a rinse, based on the belief that its purported anti-inflammatory, analgesic, and antimicrobial properties may aid in healing oral lesions. However, the rationale for its use is grounded primarily in traditional and anecdotal evidence rather than rigorous scientific validation.

There are very few, if any, published clinical studies or robust scientific investigations evaluating Rue specifically for the treatment of canker sores. Most of the references to its use for oral ulcers are found in herbal compendiums or ethnobotanical surveys rather than peer-reviewed medical literature. The limited evidence available is largely indirect, relying on the general pharmacological effects of Rue rather than direct demonstration of efficacy for oral ulcers. Additionally, Rue can be toxic if ingested in large amounts or used improperly, and its use is discouraged in some modern herbal texts due to potential side effects.

In conclusion, Rue’s application for canker sores is justified by tradition rather than scientific evidence, and its effectiveness for this purpose remains unproven in contemporary research.
