Introduction
In general, it is acceptable to consume an appropriate amount of fruit while taking traditional Chinese medicine (TCM), but the choice should be based on the properties of the herbal medicine, individual constitution, and characteristics of the fruit to avoid affecting the medicine's effectiveness or causing discomfort. It is best to wait 1–2 hours after taking the medicine, allowing partial digestion before eating fruit. This approach both supplies vitamins and dietary fiber and minimizes interference with the therapeutic effects. In daily life, it is also important to maintain a light diet while undergoing TCM treatment.

Generally, it is acceptable to consume fruits in moderation while taking traditional Chinese medicine (TCM), but the choice should be based on the properties of the herbal medicine, individual constitution, and the characteristics of the fruits, to avoid affecting the efficacy of the medicine or causing discomfort. Detailed explanation is as follows:

When taking TCM, if the medicine has a warming nature, it is advisable to avoid consuming large amounts of cold-natured fruits such as watermelon, pear, and pomelo. These fruits may weaken the effectiveness of warming herbal medicines and could also irritate the gastrointestinal tract, leading to discomfort such as bloating and diarrhea. Conversely, if the medicine has a cooling nature, intake of heat-producing fruits such as lychee, longan, and mango should be reduced to prevent exacerbating internal heat and affecting the medicine's efficacy. Fruits with neutral properties, such as apples and grapes, generally have minimal impact on the medicine's effectiveness and can be consumed in moderation. The timing of fruit consumption also requires attention; eating fruits within one hour before or after taking the medicine is not recommended, as it may cause the fruit to mix with the medicinal liquid in the gastrointestinal tract, potentially affecting drug absorption.

It is better to wait 1–2 hours, allowing partial digestion of the medicine before eating fruit. This approach both replenishes vitamins and dietary fiber and minimizes interference with the medicine's efficacy. In daily life, while taking TCM, it is also important to maintain a light diet and avoid spicy and greasy foods to enhance the therapeutic effects of the herbal treatment.
