The basis for this formula is Su He Sheng Di Tang (Perilla, Mentha & Uncooked Rehmannia Decoction) as found in the Qing dynasty book, Yan Fang Xin Bian (A New Compilation of Tested Formulas) published in 1846. This has then been modified based on a combination of Heiner Fruehauf's published research and Bob Flaws's clinical experience. This formula is also based, in part, on the rationales for Ban Xia Xie Xin Tang (Pinellia Drain the Heart Decoction), Xiao Chai Hu Tang (Minor Bupleurum Decoction), Bu Zhong Yi Qi Tang (Supplement the Center and Boost the Qi), and Xiao Yao San (Rambling Powder). Blue Poppy's version is a 10:1 extract.
