This formula is a combination of Dan Zhi Xiao Yao San (Moutan & Gardenia Rambling Powder), Suan Zao Ren Tang (Zizyphus Spinosa Decoction), and Gan Mai Da Zao Tang (Licorice, Wheat & Red Dates Decoction) with additions and subtractions. Xiao Yao San comes from the Song dynasty Tai Ping Hui Min He Ji Ju Fang (Imperial Grace Formula of the Tai Ping [Era]), while Dan Zhi Xiao Yao San dates from the mid-19th century and is first found in Wen Sheng's Nei Ke Zhai Yao (Selected Essentials of Internal Medicine). The latter two formulas both date from the late Han dynasty and come from Zhang Zhong-jing's Jin Gui Yao Lue (Essentials from the Golden Cabinet). This combination is based on research carried out in China by Zhang Guo-bin of the Ping Ding Shan Municipal Chinese Medical Hospital in Henan over a five year period from 1995-2003. Blue Poppy's version is a 9:1 extract, 500mg capsules.
