Actions: Moves qì and transforms dampness; disinhibits water and disperses swelling.
Indications: Water swelling marked by pitting edema of the extremities,
Method: Decoct with water.
Rationale: Fú líng is a bland-sweet dampness-percolating medicinal, while Bái zhú is a warm bitter dampness-drying agent. Together they fortify the spleen, thereby promoting the movement and transformation of water-damp. Zé xiè percolates water-damp, while Bīng láng and husk move qì and disinhibit water. These three agents abduct the water-damp out of the body. Sāng bái pí drains the lung (the upper source of water
) and moves water. Zǐ sū, Chén pí, Shā rén, and Mù xiāng move qì and abduct stagnation, helping the movement and transformation of water-damp. Mù guā helps the elimination of dampness, while Dēng xīn cǎo helps the Fú líng to percolate water-damp. Finally, Mài dōng is added to prevent damage to yīn humor by the water-disinhibiting agents.
