Bermuda Grass (Cynodon dactylon) has been used in various traditional medicine systems, particularly in Ayurveda and folk remedies, for the management of canker sores (aphthous ulcers). Its use is based on anecdotal reports and traditional beliefs that the plant possesses anti-inflammatory, cooling, and wound-healing properties. Practitioners have recommended chewing the grass, making a paste for topical application, or using its juice as a mouth rinse to soothe oral ulcers.

However, scientific validation for these uses is limited. There are a few in vitro and animal studies that suggest Cynodon dactylon extracts may exhibit anti-inflammatory and antimicrobial properties, which could theoretically be beneficial for minor oral lesions. Despite this, there is a lack of robust clinical trials or well-controlled studies directly assessing the efficacy of Bermuda Grass in the treatment or prevention of canker sores in humans.

In summary, while Bermuda Grass is cited in traditional medicine for supporting canker sore relief, the evidence is predominantly anecdotal and supported by tradition rather than rigorous scientific studies. Its use for this purpose should be considered with caution, given the absence of strong scientific evidence.
