Herbs that Drain Dampness 利水渗湿药《神农本草经》

Overview

The herb of choice when the urine runs cloudy: bitter and neutral, it separates the clear from the turbid in the lower burner, and it frees the channels of wind-damp besides. It is the chief of Bi Xie Fen Qing Yin. Processing steers it — wine-frying toward painful obstruction in the limbs, salt-frying toward the Kidney and turbid urination, and plain dry-frying to soften its draining edge.

Contraindications

Cautions

Draining in nature: not appropriate for frequent copious urination from Kidney-yang deficiency, nor for yin deficiency without damp, and prolonged use depletes fluids. Cloudy urine should be assessed medically before it is treated as a pattern alone — urinary infection, chyluria and proteinuria are distinct problems with distinct workups.

Contraindicated in pregnancy: Use with caution in pregnancy — practitioner supervision required
