Poria is a commonly used ingredient in both food and traditional Chinese medicine. According to traditional Chinese medical theory, it has functions including promoting diuresis to remove dampness, strengthening the spleen, and calming the mind. For conditions such as edema, abdominal distension, and loose stools caused by internal accumulation of dampness, appropriate use of Poria can help expel dampness and relieve discomfort caused by dampness. Whether used alone in decoctions, soups, or combined with other dampness-resolving ingredients such as coix seed and red beans, Poria can exert certain dampness-removing effects.

However, the effectiveness of Poria in removing dampness varies among individuals and mainly targets mild cases of dampness accumulation. When internal dampness is severe, relying solely on Poria may not be sufficient to fully resolve the issue; comprehensive regulation through dietary adjustments and physical activity is also necessary. Additionally, as Poria has a mild nature, it should be used in moderation to avoid long-term excessive consumption that may affect spleen and stomach function.

When using Poria for dampness removal in daily life, it can be stewed together with spleen-strengthening ingredients such as Chinese yam and lotus seeds to enhance the effects of strengthening the spleen and removing dampness. It is also advisable to reduce intake of raw, cold, and greasy foods to prevent exacerbation of dampness.
