Introduction
If the Chinese herbal medicine is primarily used to strengthen the spleen and stomach, and nourish qi and blood—containing ingredients such as ginseng, astragalus, and angelica—it can be taken on an empty stomach. However, if the herbal formula is strongly stimulating and contains herbs like aconite root (fuzi), dried ginger, rhubarb, or gallnut, it should not be taken on an empty stomach. These herbs contain components such as tannic acid and alkaloids, which may irritate the gastric mucosa and cause gastrointestinal discomfort when taken without food.

Generally, whether traditional Chinese medicine (TCM) can be taken on an empty stomach depends on the nature of the herbal formula. If the TCM has minimal irritancy, it is usually safe to take on an empty stomach. However, if the TCM is highly irritating, taking it on an empty stomach is not recommended. The specific analysis is as follows:

If the TCM is primarily used for strengthening the spleen and regulating the stomach, or for replenishing qi and nourishing blood—containing herbs such as ginseng, astragalus, and angelica—it can generally be taken on an empty stomach. These types of herbs have little gastrointestinal irritation and help nourish the spleen and stomach, so taking them before meals typically causes no adverse effects.

However, if the TCM is strongly irritating and contains ingredients such as aconite root (fuzi), dried ginger, rhubarb, or gallnut, it should not be taken on an empty stomach. These herbs contain components like tannic acid and alkaloids that may irritate the gastric mucosa when ingested without food, potentially causing stomach discomfort.

During TCM treatment, it is important to maintain a light diet and avoid excessive fatigue, both of which support the body's recovery process.
