Can ginger slices treat oral ulcers?

Generally, ginger slices are not recommended for directly treating oral ulcers, but they may help alleviate symptoms under specific usage methods. The detailed analysis is as follows:

Fresh ginger contains pungent and irritating components that can aggravate damaged mucosal tissue when applied directly to ulcer sites, causing severe pain and potentially worsening the injury or delaying healing. However, drying ginger slices, grinding them into powder, and mixing with a small amount of warm water to form a mild paste—or boiling dried ginger slices in water, cooling it, and using it as a mouth rinse—may provide some relief. The drying process reduces ginger's irritancy, while its active ingredients may help inhibit oral bacteria to some extent, reducing the risk of wound infection. Gentle rinsing or application may also help ease discomfort.

When using ginger-based methods to relieve oral ulcers, start with a small test application and monitor whether pain worsens; discontinue immediately if any discomfort occurs. Avoid applying fresh ginger slices directly to the affected area, and do not frequently use ginger paste or ginger water rinse to prevent excessive irritation. If an oral ulcer lasts longer than one week, increases in size, or is accompanied by fever, seek medical attention promptly. Do not rely on ginger treatments, as this may delay proper diagnosis and therapy. Maintain good oral hygiene and consume foods rich in vitamins to support ulcer recovery.
