Poria Peel Classic Formulas … Natural Herb Library

Primary Actions

Promotes urination and reduces edema - Fu Ling Pi specializes in moving superficial and generalized water swelling downward, especially puffy skin and edema of the face or limbs.
Opens the water pathways more directly than the inner sclerotium - compared with whole Fu Ling, the peel is less about digestion and Shen support and more about visible edema and damp retention.
Supports qi-moving edema formulas - it is often combined with other peels and damp-draining herbs when swelling, distention, and sluggish water movement predominate.

Wu Pi San - classic five-peel formula in which Fu Ling Pi helps reduce generalized edema and promote urination.
Fu Ling Pi with Da Fu Pi and Sheng Jiang Pi - common edema-focused pairing for puffy swelling and damp water retention.
Formulas for ascitic or abdominal water distention often use Fu Ling Pi when the skin and body surface look visibly burdened with retained fluid.

Official Chinese references describe Fu Ling Pi as sweet, bland, and neutral, entering the Lung, Spleen, and Kidney to promote urination and reduce edema.
Traditional explanation consistently contrasts it with the inner Poria body: the peel is more edema-directed, while the interior has broader Spleen and Shen actions.
Its main indications are edema, puffiness, and difficult water movement rather than palpitations or insomnia.
