Dui Yao — Core Herb Pairs
The classical two-herb combinations at the heart of this formula, as recorded on the herbs' own pages — each pair has an action neither herb has alone.
The kidney is warmed and urine astringed while cold is dispersed from the bladder, reducing frequent urination and enuresis.
Energetics dose-weighted
