Can eating pomelo quickly reduce internal heat when you have excessive internal heat?
Generally speaking, eating pomelo when experiencing excessive internal heat (commonly known as "fireiness") may have a certain auxiliary effect in reducing heat, but it cannot rapidly alleviate the symptoms. Detailed explanation is as follows:

Pomelo is a common fruit rich in water, vitamin C, dietary fiber, and various minerals. It is considered to have a cooling nature in traditional Chinese medicine. It is believed to help clear heat, reduce internal fire, stimulate saliva production, and quench thirst. Moderate consumption of pomelo can help hydrate the body, supply essential nutrients, promote intestinal motility, and aid in the elimination of metabolic waste, thus providing some relief from discomforts caused by excessive internal heat such as dry mouth and sore throat. However, excessive consumption of pomelo may irritate the gastrointestinal tract due to its cold nature, potentially causing abdominal pain, diarrhea, and other discomforts—especially for individuals with cold deficiency of the spleen and stomach. Therefore, it's important to control the amount consumed.
Pomelo can be ideally combined with other heat-clearing fruits such as pears and sugarcane to better assist in alleviating symptoms of excessive internal heat. In daily life, maintaining a light diet, drinking plenty of water, and avoiding late nights are more effective ways to reduce symptoms of internal heat and maintain physical well-being.
