are:

 

Formula Class: Moisten Dryness; Moisten LU Dryness dt Yinxu

 

Ingredients: Formula is a MODIFICATION of Zhuye Shigao Tang

(Lophatherus & Gypsum Dec) (w Maimendong increased & Zhuye & Shigao

omitted); is better Nourish ST Yin formula than Zhuye Shigao Tang;

 

Inclusion Rates (Mean & Range, %) in 5 separate formulas were:
