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.
Kidney is tonified and the Chong and Ren secured, calming the fetus.
Together they tonify the liver and kidneys, strengthen the lower back and calm the fetus.
Threatened miscarriage from kidney deficiency; Tu Si Zi is chief in the formula with these two as deputies.
