Can longan seed boiled water really cure stomach pain?
Generally, lychee seed boiled water may help alleviate mild stomach pain caused by Qi stagnation, but it is unlikely to treat stomach pain caused by organic diseases or cold-type stomach pain. If there are any concerns, it is advisable to seek medical advice in advance. The detailed explanation is as follows:

If the stomach pain is caused by emotional distress leading to Qi stagnation, characterized by mild distending pain, drinking lychee seed boiled water may help relieve discomfort by promoting Qi circulation.
If the stomach pain is caused by organic diseases such as gastric ulcer or gastritis, or by exposure to cold resulting in cold-type stomach pain, accompanied by severe pain, acid reflux, vomiting, and other symptoms, lychee seed boiled water cannot repair the gastric mucosa or dispel cold, thus being ineffective in treating the pain and potentially delaying proper treatment.
Before boiling, lychee seeds should be crushed and boiled for about 20 minutes. If the stomach pain does not improve or recurs after consumption, timely medical evaluation is necessary to identify the underlying cause for targeted treatment. Do not rely on this method to mask the symptoms.
