Tannins are a group of polyphenolic compounds commonly found in various plants, including tea, oak bark, and certain fruits. Their use in treating canker sores (aphthous ulcers) primarily stems from traditional medicine practices. Historically, tannin-rich plant extracts have been applied topically or used as mouth rinses to alleviate oral ulcers due to their astringent properties, which can help dry out and contract tissues, potentially reducing pain and inflammation.

There is some low-level scientific support for tannins' astringent and antimicrobial effects, which may contribute to symptomatic relief and possible reduction of healing time for canker sores. However, robust clinical trials specifically evaluating the efficacy of tannins for this condition are lacking. Some small studies and case reports suggest a beneficial effect, but the evidence remains limited and largely anecdotal.

Overall, the use of tannins for canker sores is rooted in traditional herbal medicine, with modest scientific rationale but insufficient high-quality clinical validation. Therefore, while tannin-containing remedies may offer some symptomatic relief for minor oral ulcers, they should be considered adjunctive at best, and not a primary evidence-based intervention.
