How long should you hold Xigua Shuang spray in your mouth?

The duration of using Xigua Shuang spray depends on the severity of the condition. Generally, as a medication intended to be dissolved in the mouth, the recommended dissolving time for Xigua Shuang spray is typically between 2 to 4 hours. For milder conditions, such as small oral ulcers, the dissolving time may only need to be around 2 hours. However, for more severe cases—such as larger ulcer areas or intense pain—the dissolving time may need to be relatively longer, approximately 4 hours or more. During the dissolving process, the medication gradually dissolves and adheres to areas under the tongue and in the pharynx, where it is absorbed through the oral mucosa to exert effects of clearing heat, detoxifying, reducing swelling, and relieving pain. It is important to note that the dissolving time should not be too short, as the medication may not fully take effect; at the same time, excessively long dissolving times should be avoided to prevent bacterial growth, which could hinder recovery. When using Xigua Shuang spray, the dissolving time should be reasonably controlled according to individual conditions and medical advice.
