Rating (out of 5): 2

Chamomile has been traditionally used for the relief of canker sores (aphthous ulcers) due to its purported anti-inflammatory, soothing, and antimicrobial properties. Historical use is documented in various traditional medicine systems, particularly in Europe and the Middle East, where chamomile infusions and topical rinses have been recommended for oral mucosal conditions, including canker sores. The mechanism is believed to involve the reduction of inflammation and promotion of mucosal healing.

Scientific evidence for chamomile’s efficacy in treating canker sores is limited but does exist. Some small clinical studies and case reports suggest that chamomile preparations (typically mouth rinses or topical applications) may help reduce pain, inflammation, and healing time of canker sores compared to placebo or conventional mouthwashes. For example, a few randomized controlled trials have shown that chamomile mouthwashes are as effective as some standard treatments in reducing lesion size and discomfort. However, these studies often have small sample sizes, methodological limitations, or lack replication, so the overall quality of evidence is considered low to moderate.

In summary, chamomile’s use for canker sores is primarily rooted in traditional medicine, with some preliminary scientific support but insufficient high-quality evidence to fully validate its effectiveness. Its safety profile is generally favorable, making it a commonly used home remedy despite limited robust clinical data.
