There is no such thing as “the best match” for Poria in water. Clinically, Poria can be combined with yam and atractylodes to make water. Poria is sweet, light and flat in nature, belonging to the heart, lungs, spleen and kidney meridians, with the effect of diuresis and elimination of edema, seepage of dampness, strengthening the spleen, and tranquilizing the heart. The drug is used to treat edema, spleen deficiency and diarrhea (diarrhea caused by a weak spleen), insomnia, loose stools and diarrhea, and insomnia and restlessness. The adverse effects of Poria are not clear, but it should be noted that it should not be taken by patients with yin deficiency without dampness-heat. In clinical practice, Poria can be combined with yam and atractylodes to make water. If Poria is paired with Chinese yam, it can benefit qi and tonify blood (replenish qi and blood in the body), and diuretically nourish yin. Poria and Rhizoma Atractylodis Macrocephalae are good for tonifying the center of the body (by replenishing the spleen to treat qi deficiency) and diuretic effect, which can improve the symptoms of dizziness and edema caused by spleen deficiency. It should be noted that the efficacy of taking it in water is limited and cannot be used to treat diseases. If you need to use this medicine, it is recommended to go to a regular hospital for consultation and treatment under the guidance of a professional physician for evidence-based treatment.
